The Latitude-Longitude Grid

The video explains the latitude-longitude grid system used to locate places on Earth. Latitude lines run horizontally, with the equator at zero degrees, dividing the Earth into Northern and Southern Hemispheres. The tropics lie between the Tropic of Cancer and Tropic of Capricorn. Longitude lines run vertically, with the Prime Meridian at zero degrees, dividing the Earth into Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England. Latitude and longitude lines form a grid, allowing precise location identification using coordinates, such as New Orleans at 30°N, 90°W.
