Weathering, Erosion, and Deposition

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.
• makes the rocks last longer.
• expands cracks and breaks rocks.
• causes rocks to fall in landslides.

The process that breaks down rocks and other materials on Earth's surface is called

• Weathering
• Erosion
• Deposition
• Decomposition

Over long periods of time, deposition may change the Earth’s surface by _____.

• forming new land features.
• breaking down large rocks into smaller ones.
• washing away beaches.
• moving topsoil.

A cliff formed near the ocean.  Which statement best describes how this cliff formed?

• Warm air melted the rock.
• Sun rays evaporated the rock.
• Ocean waves washed away rock.
• Plant roots pushed away the rock.

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.

Muddy water being carried away by a fast-moving river is an example of

• Weathering
• Erosion
• Deposition 
• A nice place to swim

How do plants weather rocks?

• During photosynthesis
• 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.
• Plants don't weather rocks.
