Question

biological weathering is driven by organisms like plants, lichens, and mosses, accelerating rock breakdown by chemically altering rock substances. which of these describes physical weathering? rocks being broken down by freezing and thawing plants, lichens, and mosses breaking down rocks minerals in rocks being broken down chemically

Explanation:

Physical weathering involves physical forces like freezing - thawing cycles that break rocks without changing their chemical composition. Biological weathering is by organisms (plants, lichens, mosses) and chemical weathering is when minerals are chemically broken down.

Answer:

A. rocks being broken down by freezing and thawing
