Question

question 6 of 32 which of these is an agent of wedging? a. plant roots b. carbon dioxide c. acid rain d. high winds

Explanation:

Wedging is a physical weathering process. Plant roots can grow into cracks in rocks, and as they grow larger, they exert pressure and wedge the rock apart. Carbon - dioxide is more related to chemical weathering (e.g., in the formation of carbonic acid), acid rain is a chemical weathering agent due to its acidic nature reacting with rocks, and high winds are an agent of erosion and abrasion rather than specifically wedging.

Answer:

A. Plant roots
