Plains form in many different ways. Some plains form as ice and water erodes or wears away the dirt and rock on higher land.

How did the rock of the Great Plains form?

The plate motion that occurred near the Great Plains and Rocky Mountains uplifted igneous rock that formed underground.

Why do mountains and plains experience different weather?

This happens because as altitude increases air becomes thinner and is less able to absorb and retain heat. The cooler the temperature the less evaporation there is meaning that there is more moisture in the air. Air pressure decreases with altitude.
