Weathering and Soil TEST UNIT

Water chemically breaks down rock because 

• water expands when it freezes
• materials in the water are deposited
• acides in water react with chemicals in the rock
• water is not affected by wind 

Which of the following areas would experience the most weathering?

• an area with heavy rains, constant temperatures, and gentle winds
• an area with constant heat, minimal rain, and high winds
• an area with high winds, heavy rain, hot summers, and freezing winters
• all areas generally have the same amounts of weathering 

which of the following is a type of frost action?

• abrasion
• oxidation
• ice wedging
• gravity
