In its purest sense, topography is a look at features of the Earth and natural and manmade formations on Earth. Topographical maps help us get a true sense of an area. They show height changes and features of any area. These maps show us where land elevates or descends and where water forms come into play. Most contour maps, these days, are generated by satellite images. Many satellites have the capability to self-draw these maps.
The worksheets look at oceanic currents, reading contour and topographical maps, the makeup of river systems, reading all forms of maps, and making your own topographical maps.
