NREM 301 Exam 1 Questions and Answers Graded A+ What is the difference between physical and chemical weathering? Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, while chemical weathering involves changes to the minerals in the rock due to reactions with water, air, or other chemicals. How does frost wedging contribute to physical weathering? Frost wedging occurs when water enters cracks in rocks, freezes, expands, and breaks the...
