Weathering is a process that helps make soil. Choose the statement that DOES NOT describe how rocks may be weathered.

• Rock pieces are moved from place to place.

• Living things, like moss and lichens, break down rocks.

• Plant roots can grow between cracks in rocks.

• Water fills tiny spaces inside a rock.

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

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

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves

Erosion ________________________.

• breaks down rock

• moves rocks

• deposits rock
