What is the process that picks up and moves weathered rocks?

• Deposition

• Landslide

• Weathering

• Erosion

Deposition changes the Earth’s surface because bits of broken rock and soil _____

• stop rivers from flowing.

• make rich farmlands.

• are dropped in new places.

• move very slowly.

• When roots grow into cracks of rocks and expand the rock breaks.

• When the plant moves water from the roots to the leaves, the rock breaks.
