How does frost wedging cause cracks in rocks to become larger?

• Ice contracts when it freezes, pulling the rocks together.

• Ice melts when it freezes, causing the rocks to slide apart.

• Ice expands when it freezes, pushing the rocks apart.

• Ice sublimates when it freezes, creating gaps in the rocks.

Which type of weathering is more important in a warm or a cold climate?

• Frost wedging in a warm climate.

• Abrasion in a cold climate.

• Pressure release in a warm climate.

• Frost wedging in a cold climate.

What are three different ways that rocks can be worn down by abrasion?

• Glaciers dragging rocks over bedrock, wind carrying sand can wear down rocks, and rocks can be worn away in rivers.

• Rocks can be worn down by animals, plants, and ice.

• Rocks can be worn down by chemical reactions, heat, and pressure.

• Rocks can be worn down by volcanic activity, earthquakes, and landslides.
