The Global Positioning System (GPS):network of satellites used to find places on the Earth. Longitude: the distance in degree east or west of the prime meridian. A hemisphere is half of a sphere.ġ1 Longitude Prime Meridian: imaginary line stretching from North Pole to South Pole. Latitude: distance in degrees north or south of the equator. They form an imaginary grid over the Earth’s surface.ġ0 Latitude Equator: imaginary line dividing the Earth into northern and southern hemispheres.

How would a traveler benefit from using a relief map vs a globe?Ĥ Mountains Mountain range :group of mountains connected in aĥ Plateaus and Plains Plateaus have fairly leveled surfaces but stand above sea level, usually found near large mountain ranges. Mapmaker uses satellites and photo images to build a 3D view of Earth’s surface. Shows 3 main land features: mountains, plains, and plateaus. Globes have a sphere shape showing relative sizes and shapes of earth’s land features and waters.ģ Land features on a map Relief maps show high and low features.
