The process by which rock, soil, and other weathered earth materials are moved from one place to another.

Flood water pounding against a canyon wall and wearing it down

A mudslide flowing down a steep hill

Water getting into cracks, freezing, and breaking the rock apart

Wind blasting sand at rock and carving out arches

Muddy water being carried away by a fast-moving river

Flood waters moving soil from one location to another

The movement of rocks from one location to another

A glacier breaking off pieces of rock in its path

A seed germinates in the crack of a rock

Rain washing away soil from a hillside

A glacier sliding down a hill

Wind blowing sand from one location to another

A glacier dragging rocks across Earth's surface

Rocks being made smooth by tumbling over a stream

The process of breaking down rock into sediments

The freezing and thawing of water cracking pieces off of a rock

Gravity pulling a rock down a hill

Wind smoothing the edges of a large boulder
