Detailed explanation-1: -The statement is false. Plants, animals, water, ice, acid, salts and temperature change, all causes weathering of rocks.

Detailed explanation-2: -Biological weathering is caused by the movements of plants and animals. For example, a rabbit can burrow into a crack in a rock making it bigger and eventually splitting the rock, or a plant may grow in a crack in a rock and, as its roots grow, cause the crack to widen.

Detailed explanation-3: -Weathering and People Weathering is a natural process, but human activities can speed it up. For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere.

Detailed explanation-4: -Biological weathering occurs when plants break up rocks with roots or root exudates. The process is slow, but may strongly influence landscape formation.

Detailed explanation-5: -Living organisms such as plant roots, lichens, mosses and others are highly responsible for biological weathering of the rocks.
