How does wind cause weathering?

• Wind cannot cause the weathering of rocks.

• Wind can blow sand and create new landforms.

• Wind picks up sand or dry soil and carries it from one place to another.

• Blowing sand can wear away a rock's surface and break it into smaller pieces.

Weathering is a process that helps make soil. All but one statement describes how rocks may be weathered. That is:

• Water fills tiny spaces inside a rock.

• Rock pieces are moved from place to place.

• Plant roots can grow between cracks in rocks.

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

How do wind and water change rocks over time?

• They add minerals to the rocks.

• They change the shape of the rocks.

• They increase the mass of the rocks.

• They build up the rocks with small sand particles.

The accompanying diagram shows granite bedrock with cracks. Water has seeped into the cracks and frozen. The arrows represent the directions in which the cracks have widened over time. Which State best describes the type of weathering shown by the diagram?

• Physical weathering - enlargement of the cracks occurs because water expands when it freezes

• Physical weathering - occurs only in bedrock composed of granite

• Chemical weathering - the cracks become wider because of chemical reactions between water and the rock

• Chemical weathering - common in regions of primarily warm and humid climates
