Question

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

Explanation:

Biological weathering occurs when living organisms like plants, lichens, and mosses interact with rocks. These organisms can grow in cracks of rocks, and as they grow, they exert pressure, causing the rocks to break apart. Also, some organisms release chemicals that can react with rocks and contribute to their breakdown.

Answer:

plants, lichens, and mosses accelerating breakdown
