Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals through natural processes such as wind, water, and temperature changes.
