Despite its name, no part of Equatorial Guinea lies on the equator. Learner's definition of EQUATOR. At the equator there is a tropical climate, and travelling south of the equator it gets cooler again before reaching the Antarctic. Temperate climates are found a bit further south, and as you approach the equator you find Mediterranean and desert climates. 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 ). 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. Changes in Earth axis can also be observed in the geographic layout of volcanic island chains, which are created by shifting hot spots under the Earth's crust as the axis and crust move. This is slightly above the snow line and is the only place on the equator where snow lies on the ground. Although the rings extend thousands of kilometers into space, they are actually very thin, only about a kilometer wide. There are about 200 rainy days per year and average annual sunshine hours are around 2,000. The Tropic of Capricorn is the latitude that lies at 23° 26′ South of the Equator. This clip is from : Primary Geography , Weather: World Weather ... Morocco’s location near the geographic equator makes it an interesting site for ionospheric measurements. 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 equator is a line which is not real drawn around a sphere or planet, such as the Earth. Despite high year-round sea level temperatures, some higher altitudes such as the Andes and Mount Kilimanjaro have glaciers. The equator is important as a reference point for navigation and geography. 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. Equatorial definition, of, relating to, or near an equator, especially the equator of the earth. The north pole is north of the Equator and the south pole is south of the Equator. Southern latitudes can also be expressed as negative number where -90° is at the South Pole. [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. The equator is important as a reference point for navigation and geography. However, its island of Annobón is 155 km (96 mi) south of the equator, and the rest of the country lies to the north. [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. Average annual temperatures in equatorial lowlands are around 31 °C (88 °F) during the afternoon and 23 °C (73 °F) around sunrise. equator definition: 1. an imaginary line drawn around the middle of the earth an equal distance from the North Pole and…. The Equator is the parallel line located at 0°00’00”. Near the equator, there is little temperature change throughout the year, though there may be dramatic differences in rainfall and humidity. The latitude of the equator is defined as zero degrees. 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. The latitude of the Earth's equator is, by definition, 0° (zero degrees) of arc. 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. An example of the equator is the latitude of 0°. 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). The Indian Ocean (between the Huvadhu … Equator definition is - the great circle of the celestial sphere whose plane is perpendicular to the axis of the earth. 2. the great circle of the earth that is equidistant from the North Pole and South Pole. Latitudes south of the Equator … The IUGG standard meridian is, to the nearest millimetre, 40,007.862917 kilometres (24,859.733480 mi), one arc-minute of which is 1,852.216 metres (6,076.82 ft), explaining the SI standardization of the nautical mile as 1,852 metres (6,076 ft), more than 3 metres (9.8 ft) less than the geographical mile. 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. The sea-level surface of the Earth (the geoid) is irregular, so the actual length of the equator is not so easy to determine. A circle of latitude is an imaginary ring linking all points sharing a parallel. If it were really circular, the length of the equator would then be exactly 2π times the radius, namely 40,075.0142 km (24,901.4594 mi). BSL Geography Glossary - Equator - definition. All lines are parallel to each other and are thus also known as parallels. Some of the hottest places on … 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. 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. 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 distance around the Equator is about 24,900 miles (40,000 kilometers). 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). 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. Equator Pure Nature seeks to improve people's lives by promoting the replacement of chemical cleaning products with natural, healthy cleaning products, which products EPN believes can both decrease rates of allergies and asthma and decrease the contamination of the environment.
