Today I will write about a few different types of plains such as lake plains, glacial plains, and lava plains.
Lake plains form when water brings and drops sediments into a lake. When that lake dries, it becomes a plain. Sometimes glaciers make the ground around them flat by eroding the rock to a flat surface, carving a plain. The sediments in the ice cover the plain when the ice melts. Another way a plain can form is when a pool of lava dries and hardens. It forms a rock called lava rock, a rock which you might have in your back yard.
Now I will write about plateaus. A plateau is a high, generally flat, piece of land.
A fault plateau is formed when a fault pushes up on the land. It breaks the rock and forms a cliff connecting the land that got pushed up and the land that stayed level. A lava plateau is formed when lava gets laid down in layers and hardens before the next layer comes. Mesas are mini plateaus, and buttes are mini mesas.
