Question

question 4 1 pts which of the following is not an example of physical weathering? oxidation exfoliation frost wedging thermal expansion question 5 1 pts which of the following is the most common end - product of the chemical weathering of feldspars? clay minerals calcite oxidized horizons amphiboles

Explanation:

Physical weathering involves mechanical breakdown of rocks without changing their chemical composition. Oxidation is a chemical - change process where substances react with oxygen, so it's not physical weathering. Feldspars undergo chemical weathering to form clay minerals as a common end - product due to chemical reactions like hydrolysis.

Answer:

Question 4: A. oxidation
Question 5: A. clay minerals
