Question

choose the correct answer. how does biological weathering occur? by chemically breaking down rocks by gases due to physical factors such as freezing and thawing plants, lichens, and mosses accelerating breakdown

Explanation:

Biological weathering involves living - organisms like plants, lichens, and mosses. They can grow on rocks, secrete substances, or physically penetrate rocks, accelerating rock breakdown. Chemical breakdown by gases is chemical weathering, and physical factors like freezing and thawing are physical weathering.

Answer:

C. plants, lichens, and mosses accelerating breakdown
