Latitude is the measure up of street north or southern of the Equator. That is measured v 180 imaginary lines that type circles about the planet east-west, parallel come the Equator. This lines are well-known as parallels. A circle of latitude is an imagine ring linking all points sharing a parallel.The Equator is the heat of 0 degrees latitude. Each parallel procedures one degree north or southern of the Equator, v 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude the the north Pole is 90 degrees N, and also the latitude the the southern Pole is 90 levels S. Choose the poles, some circles that latitude room named. The Tropic of Cancer, for instance, is 23 degrees 26 minute 21 seconds N—23° 26" 21"" N. That twin, the Tropic that Capricorn, is 23° 26" 21"" S. The tropics are crucial geographic areas that note the northernmost and also southernmost latitudes where the sun have the right to be seen directly overhead during a solstice.One degree of latitude, dubbed an arcdegree, covers about 111 kilometers (69 miles). Due to the fact that of the Earth"s curvature, the farther the circles room from the Equator, the smaller they are. At the North and South Poles, arcdegrees are simply points.Degrees of latitude are separated into 60 minutes. To it is in even much more precise, those minute are divided into 60 seconds. One minute that latitude covers around 1.8 kilometers (1.1 miles) and also one second of latitude covers about 32 meters (105 feet).For example, the latitude for Cairo, Egypt, in degrees and minutes would be written as 29° 52" N, since the city is 29 degrees, 52 minutes phibìc of the Equator. The latitude for Cape Town, south Africa, would be 33° 56" S, since the city is 33 degrees, 56 minutes south of the Equator. Using secs of latitude, global positioning device (GPS) devices can decide schools, houses, also rooms in one of two people of these towns.Similar to latitude, the equivalent measurement of distance roughly the planet is dubbed longitude. The imaginary lines the latitude and also longitude intersect each other, creating a grid that covers the Earth. The points of latitude and longitude are called coordinates, and can be used together to locate any allude on Earth.
