The earth is a huge sphere of rock covered by water and soil, and surrounded by air. About 70% of the Earth’s surface is covered with water, most of it in the oceans. Land makes up about 30%.
Earth’s crust has a very interesting and varied landscape made up of mountains, valleys, plains, deserts, oceans, lakes, rivers and icecaps.
-
1. Mountains are large landforms that rise above the surrounding land.
-
2. Valleys are depressions on the Earth’s surface.
-
3. Plains are areas of relatively level, treeless land.
-
4. Deserts are areas with very little water available.
-
5. Oceans are huge bodies of water that cover most of our Earth.
-
6. Lakes are bodies of water that form in hollows or basins.
-
7. Rivers are streams of water moving across the land.
-
8. Icecaps are huge areas of ice found at the North and South Poles.
Geologists investigate materials of Earth’s crust such as soil, sand, and rocks.
