What is a physical process that breaks rocks without changing the make up of the rock?

• chemical weathering
• mechanical weathering
• erosion
• deposition

Oxygen in the air reacts with rocks to produce rust.

• carbonation
• oxidation
• acid rain
• abrasion

Gravity pulls large amounts of soil, rock debris down steep-sided hills and mountains.

• abrasion
• deposition
• canyon
• mass movement

Acid in groundwater dissolves rock.

• mechanical weathering
• chemical weathering

Rocks in a riverbed become smooth from tumbling.

• mechanical weathering
• chemical weathering

Water freezes and expands in cracks in rocks breaking the rock.
