the distance in degrees east or west of the prime meridian. The prime meridian and the 180 degree meridian combine to divide Earth into east or west halves, or hemispheres the eastern or western hemisphere. East of the prime meridian, longitude is measured in degrees west. They both meet at the 180 degrees meridian. All the meridians pass through the North Pole and the South Pole.
the distance in degrees north or south of the equator. Unlike lines of longitude, lines of latitude are parallel. The equator is the largest circle. All the other circles become smaller and smaller the closer they are to Earth's poles.
Imagine a light at the center of a globe. It would throw shadows of the continents and the latitude and longitude lines onto a sheet of paper if it were wrapped around the globe. Because the paper is shaped like a cylinder, this is called a cylindrical projection. The resulting map represents shapes near the poles are enlarged. Notice that in the cylindrical projection, Greenland appears to be larger than South America. However, Greenland is about one-eighth the size of South America.
The shape of the land surface is called topography. A topographic map shows the detailed shapes of Earth's surface, along with its natural and human-made features.
is drawn as if you were looking down on an area from above Earth's surface. Map view can also be referred to as plain view.
is a drawing that shows an object as though you were looking at it from the side. A profile view is like a side view of a house.
is the process of collecting information about an area without coming into physical contact with it. There are many applications for remote sensing. This process produces maps that show detailed information about agriculture, forestry, geology, land use, and many other subjects. Often these maps cover huge areas.
