At the equator, the snow line is around 1,000 metres (3,300 ft) lower than on Mount Everest and as much as 2,000 metres (6,600 ft) lower than the highest snow line in the world, near the Tropic of Capricorn on Llullaillaco. Sometimes, latitudes north of the Equator are denoted by a positive sign. 2. the great circle of the earth that is equidistant from the North Pole and South Pole. Learn more. A circle of latitude is an imaginary ring linking all points sharing a parallel. The plane of Earth's equator, when projected outwards to the celestial sphere, defines the celestia… Equinox definition, the time when the sun crosses the plane of the earth's equator, making night and day of approximately equal length all over the earth and occurring about March 21 (vernal equinox, or spring equinox ) and September 22 (autumnal equinox ). Giga-fren. Equator (religion, spiritualism, and occult) The equator is the imaginary line drawn around Earth (and, by extension, other celestial bodies), separating it into northern and southern hemispheres. The Equator is a line that goes around the middle of the Earth. The equator is one of the five notable circles of latitude on Earth; the other four are both polar circles (the Arctic Circle and the Antarctic Circle) and both tropical circles (the Tropic of Cancer and the Tropic of Capricorn). Aviation Week and Space Technology on 9 October 1961 reported that measurements using the Transit IV-A satellite had shown the equatorial diameter from longitude 11° West to 169° East to be 1,000 feet (305 m) greater than its diameter ninety degrees away. The Equator is the parallel line located at 0°00’00”. This also results in a corresponding movement of the equator away from the subsolar point, which is then situated over or near the relevant tropic circle. equator definition: 1. an imaginary line drawn around the middle of the earth an equal distance from the North Pole and…. It is the imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. Lowlands around the equator generally have a tropical rainforest climate, also known as an equatorial climate, though cold ocean currents cause some regions to have tropical monsoon climates with a dry season in the middle of the year, and the Somali Current generated by the Asian monsoon due to continental heating via the high Tibetan Plateau causes Greater Somalia to have an arid climate despite its equatorial location. The Equator is an arbitrary line dividing the Earth between the Northern and Southern Hemisphere. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. The equator divides the Earth into the Northern and Southern hemispheres. DEFINITION. Look it up now! If you could cut the Earth in half, the Equator would be the line where both hemispheres meet. It is one of the lines known as a line of latitude, or circle of latitude. Near the equator, there is little temperature change throughout the year, though there may be dramatic differences in rainfall and humidity. Latitude has three different kinds. This clip is from : Primary Geography , Weather: World Weather The Equator’s covers a distance on the Earth’s surface approximately 24,901 miles long. a equator, from aequare to make equal), in geography, that great circle of the earth, equidistant from the two poles, which divides the northern from the southern hemisphere and lies in a plane perpendicular to the axis of the earth; this is termed the "geographical" or "terrestrial equator." By definition, the latitude of the Earth’s equator is 0 degrees, while the Tropic of Cancer and the Tropic of Capricorn each lie at 23.5 degrees latitude. 3. a circle separating a surface into two congruent parts. On Earth, the Equator, at 0° latitude, divides the Northern and Southern Hemispheres. What is latitude? This effect must be accounted for in detailed geophysical measurements. Hemisphere definition is - a half of the celestial sphere as divided into two halves by the horizon, the celestial equator, or the ecliptic. Here, the prevailing trade winds of the northern hemisphere blow to the southwest and collide with the southern hemisphere’s driving … Definition: Imagine the Earth, with the North Pole at the top and the South Pole at the bottom. See more. [6] It is also the equatorial radius used for the IERS 2003 ellipsoid. The length of daylight (sunrise to sunset) is almost constant throughout the year; it is about 14 minutes longer than nighttime due to atmospheric refraction and the fact that sunrise begins (or sunset ends) as the upper limb, not the center, of the Sun's disk contacts the horizon. The plane of Earth's equator, when projected outwards to the celestial sphere, defines the celestial equator. BSL Geography Glossary - Equator - definition. The earth is commonly modeled as a sphere flattened 0.336% along its axis. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy.Different factors, including genetics and some viruses, may contribute to type 1 diabetes. Equator definition, the great circle on a sphere or heavenly body whose plane is perpendicular to the axis, equidistant everywhere from the two poles of the sphere or heavenly body. In the past, these ceremonies have been notorious for their brutality, especially in naval practice. At the equinoxes, the Earth's axis is perpendicular to the sun rather than tilted toward or away, meaning that day and night are both about 12 hours long across the whole of the Earth. The geography of Ecuador is quite diverse for a country that only covers a total of 283,560 square kilometers - of which 6,720 square kilometers is made up of water. Starting at the Prime Meridian and heading eastwards, the equator passes through: Passing just south of Baker Island, and just north of Jarvis Island,  United States Minor Outlying Islands. To a person on Earth, the Sun appears to travel above the equator (or along the celestial equator) at these times. Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. Near the equator, this means the variation in strength of solar radiation is different relative to the time of year than it is at higher latitudes: Maximum solar radiation is received during the equinoxes, when a place at the equator is under the subsolar point at high noon, and the intermediate seasons of spring and autumn occur at higher latitudes, and the minimum occurs during both solstices, when either pole is tilted towards or away from the sun, resulting in either summer or winter in both hemispheres. Some of the hottest places on … An imaginary line around the Earth midway between the poles. Although type 1 diabetes usually appears during childhood or adolescence, it can develop in adults.Despite active research, type 1 diabetes has no cure. Is it near the equator? The equator is an imaginary line that runs from east to west on Earth's surface and is exactly halfway between the north and south poles (the northernmost and southernmost points on the Earth). Light rays from the Sun's center are perpendicular to Earth's surface at the point of solar noon on the equator. The International Association of Geodesy (IAG) and the International Astronomical Union (IAU) have chosen to use an equatorial radius of 6,378.1366 km (3,963.1903 mi) (codified as the IAU 2009 value). The deposits by thermal currents are determined by the axis of the earth, which determines solar coverage of the Earth's surface. Despite its name, no part of Equatorial Guinea lies on the equator. Despite high year-round sea level temperatures, some higher altitudes such as the Andes and Mount Kilimanjaro have glaciers. It is identified as the latitude that falls at the point that is equidistant from the North Pole and the South Pole. The equator is important as a reference point for navigation and geography. DEFINITION. … [2], Sites near the equator, such as the Guiana Space Centre in Kourou, French Guiana, are good locations for spaceports as they have a fastest rotational speed of any latitude, 460 m (1,509 ft)/sec. The sun is perpendicular to the Equator twice a … 1. the great circle on a sphere or heavenly body whose plane is perpendicular to the axis and everywhere equidistant from the poles. These lines are known as parallels. The Tropic of Capricorn is the latitude that lies at 23° 26′ South of the Equator. Earth bulges slightly at the equator; the "average" diameter of Earth is 12,750 km (7,922 mi), but the diameter at the equator is about 43 km (27 mi) greater than at the poles. The equator is important as a reference point for navigation and geography. The distance around the Equator is about 24,900 miles (40,000 kilometers). Experts can attempt the prime meridian or the tropic of breast cancer. The Equator is the parallel line located at 0°00’00”. The equator is the only line of latitude which is also a great circle—that is, one whose plane passes through the center of the globe. Latitude is a system of imaginary east-west lines, called parallels, that encircle the Earth parallel to the equator. The equator divides the Earth into the Northern and Southern hemispheres. The circumference, or distance around, the equator is about 24,900 miles (40,000 kilometers). Brush up on your geography and finally learn what countries are in Eastern Europe with our maps.

The equator is a line which is not real drawn around a sphere or planet, such as the Earth.It is one of the lines known as a line of latitude, or circle of latitude.The name "equator" is Latin for "even-maker"; at equator the day and night are exactly the same length around the year.. During Saturn's equinoxes, the rings (and Saturn's equator) line up perfectly with the sun. In the cycle of Earth's seasons, the equatorial plane runs through the Sun twice per year: on the equinoxes in March and September. The Equator’s covers a distance on the Earth’s surface approximately 24,901 miles long. Latitude and longitude, coordinate system by means of which the position or location of any place on Earth’s surface can be determined and described. Earth's Equator (spelled with capital E) is a specific case of a planetary equator. The sun is perpendicular to the Equator twice a … It's an imaginary line that divides the Earth into two equal halves, and it forms the halfway point between the South Pole and the North Pole at 0 degrees latitude, according to National Geographic. The equator is defined as an imaginary line drawn on the Earth and spaced equally between the North and South Pole. The Equator is the line of 0 degrees latitude. For both GRS 80 and WGS 84, this results in a length for the equator of 40,075.0167 km (24,901.4609 mi). In geography, latitude is the distance on the earth’s surface, north or south of the Equator, expressed in angular measurements from 0° at the Equator to 90° (North or South). Locations on the equator experience the shortest sunrises and sunsets because the Sun's daily path is nearly perpendicular to the horizon for most of the year. The equator is a line which is not real drawn around a sphere or planet, such as the Earth. The latitude of the Earth's equator is, by definition, 0° (zero degrees) of arc. The Atlantic Ocean (at the Gulf of Guinea and the Perigoso Canal) 2. It is identified as the latitude that falls at the point that is equidistant from the North Pole and the South Pole. It is one of the lines known as a line of latitude, or circle of latitude. See more. [3], The precise location of the equator is not truly fixed; the true equatorial plane is perpendicular to the Earth's rotation axis, which drifts about 9 metres (30 ft) during a year. [citation needed], Intersection of a sphere's surface with the plane perpendicular to the sphere's axis of rotation and midway between the poles, "Moonport: A History of Apollo Launch Facilities and Operations", https://www.discovermagazine.com/environment/millions-of-years-ago-the-poles-moved-and-it-could-have-triggered-an-ice-age, "The IAU 2009 system of astronomical constants: the report of the IAU working group on numerical standards for Fundamental Astronomy", "General definitions and numerical standards", "Memoria Técnica de la Determinación de la Latitud Cero", https://en.wikipedia.org/w/index.php?title=Equator&oldid=995778585, Wikipedia indefinitely move-protected pages, Articles with unsourced statements from October 2020, Articles with unsourced statements from April 2017, Articles with unsourced statements from March 2012, Articles with unsourced statements from January 2015, Wikipedia articles with WorldCat-VIAF identifiers, Creative Commons Attribution-ShareAlike License, Passing 4.3 km (2.7 mi) north of the border with, This page was last edited on 22 December 2020, at 21:07.

When you are fucking a girl and when you are about to cum, pull out, tell the girl to spin like a top, and you leave a nice trail around her waist. The Earth is widest at its Equator. At the equator there is a tropical climate, and travelling south of the equator it gets cooler again before reaching the Antarctic. The GRS 80 (Geodetic Reference System 1980) as approved and adopted by the IUGG at its Canberra, Australia meeting of 1979 has an equatorial radius of 6,378.137 km (3,963.191 mi). These statistics include the Galapagos Islands which form part of Ecuador. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. When the Sun is directly above the Earth's Equator (on the equinoxes of approximately March 20 and September 23), sunlight shines perpendicular to the Earth's axis of rotation, and all latitudes have a 12-hour day and 12-hour night. Saturn's spectacular ring system orbits in the same plane as the planet's equator. [5] This equatorial radius is also in the 2003 and 2010 IERS Conventions. The Indian Ocean (between the Huvadhu … Although the rings extend thousands of kilometers into space, they are actually very thin, only about a kilometer wide.

However, its island of Annobón is 155 km (96 mi) south of the equator, and the rest of the country lies to the north. It also divides the Earth into the northern hemisphere and the southern hemisphere and is an important line of latitude for navigational purposes. Geocentric; Astronomical; Geographic The celestial equator refers to the circle that results when one imaginarily projects the terrestrial equator against the background of the fixed stars. An equator is the intersection of a sphere's surface with the plane perpendicular to the sphere's axis of rotation and midway between the poles. This is a difference of less than one millimetre (0.039 in) over the total distance (approximately 1.86 kilometres or 1.16 miles). Geological samples show the equator significantly changed positions between 12 and 48 million years ago, as sediment deposited by ocean thermal currents at the equator have shifted. Lines of latitude run parallel to the Equator. Nevertheless, temperatures are high year round due to the earth's axial tilt of 23.5° not being enough to create a low minimum midday declination to sufficiently weaken the sun's rays even during the solstices. Seasons result from the tilt of the Earth's axis compared to the plane of its revolution around the Sun. resources for Geography topic covering teaching children about the equator and the oceans of the world The equator is a line which is not real drawn around a sphere or planet, such as the Earth. translation and definition "geographical equator", Dictionary English-English online. 4. celestial equator. Latitude is a system of imaginary east-west lines, called parallels, that encircle the Earth parallel to the equator. The geographical mile is defined as one arc-minute of the equator, so it has different values depending on which radius is assumed. Find more ways to say equator, along with related words, antonyms and example phrases at Thesaurus.com, the world's most trusted free thesaurus. What is latitude? Another word for equator. This makes the equator 0.16% longer than a meridian (a great circle passing through the two poles). Indonesia is the country straddling the greatest length of the equatorial line across both land and sea. All lines are parallel to each other and are thus also known as parallels. How to use hemisphere in a sentence. Equator definition is - the great circle of the celestial sphere whose plane is perpendicular to the axis of the earth. By definition, the latitude of the Earth’s equator is 0 degrees, while the Tropic of Cancer and the Tropic of Capricorn each lie at 23.5 degrees latitude. The city of Quito, Ecuador, lies very close to the equator. The geographic coordinates of New York City, for example, are 40° N, 74° W, meaning that it is located 40 degrees north latitude and 74 degrees west longitude. Because the sun is closer to the equator, than the Tropic of Cancer and Tropic of Capricorn Evidence: Professorial Geography Teacher, currently running my own Geography A-Level Course (like a school) It is the southern-most position on the globe, where the Sun is directly overhead during the December Solstice. An equator is an imaginary line around the middle of a planet or other celestial body.It is halfway between the North Pole and the South Pole, at 0 degrees latitude.An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. It is about 40,075 km (24,901 mi) long, of which 78.8% lies across water and 21.3% over land. The added velocity reduces the fuel needed to launch spacecraft eastward (in the direction of Earth's rotation) to orbit, while simultaneously avoiding costly maneuvers to flatten inclination during missions such as the Apollo moon landings. Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin. M0980 Meteorological equator The annual mean position of the equatorial trough which lies near 5°N rather than on the geographical equator. The terms summer, autumn, winter and spring do not generally apply. Climatology defination nature and scope the study of the earth falls into four broad categories i. Geographical study involves the earth its aspects and formation process causal and spatial relation of humans with their environment also the interaction of humans with the environment around them. The sea-level surface of the Earth (the geoid) is irregular, so the actual length of the equator is not so easy to determine. Average annual temperatures in equatorial lowlands are around 31 °C (88 °F) during the afternoon and 23 °C (73 °F) around sunrise. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. That is the building’s absolute location. On and near the Equator sunlight comes from almost directly above every day year-round, and thus the Equator has a rather stable daytime temperature the whole year. Equator definition is - the great circle of the celestial sphere whose plane is perpendicular to the axis of the earth. Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. Globally, the equator crosses the following bodies of water: 1. Find definitions for: e•qua•tor. The latitude of the equator is defined as zero degrees. https://www.thefreedictionary.com/Equator+(geography), [1350–1400; Middle English < Medieval Latin, two points on the surface of the earth diametrically opposite each other. 4. celestial equator.
