Plates move along side each other cracking the Earth's crust.

Water, ice, chemicals, plants break apart rock.

When wind, water, and ice move weathered rock.

Plateaus off the coasts of continents.

Tectonic activity makes cuts in the ocean floors.

Water that filters through soil.

Ground water gathers in layers of rock under the Earth's surface.
