• a fast moving river carries rocks down stream

• the soil from a hillside is washed away by rain

• Rainwater enters the cracks of a rock, it freezes and causes the rock to break apart

• wind blowing sand from one location to another

• Plant roots grow in a rock and cause it to split

• fast running water causes rocks to hit each other breaking them down into smaller rocks

• when glaciers melt, they drop the rocks they were carrying

• flood water pounds against a wall and wears it down

• layers of sediment forming at the bottom of the ocean

• sand is dropped when the wind stops blowing and forms sand dunes

• waves dropping sand on the beach

• a mudslide flowing down a steep hill

The process where rock is dissolved, worn away, or broken down into smaller pieces
