No, acids cause chemical weathering.
No, the acids from a plant's roots that break up rock is an example of chemical weathering, not mechanical weathering. Chemical weathering involves the breakdown of rocks through chemical processes, such as acids dissolving minerals in the rock. Mechanical weathering, on the other hand, involves the physical breaking down of rocks into smaller pieces without altering their composition.

Water causes mechanical and chemical weathering.
Factors such as temperature, precipitation, type of rock, vegetation cover, and human activity can influence both chemical weathering (breakdown of rocks through chemical reactions) and mechanical weathering (physical breakdown of rocks into smaller pieces). Temperature can affect the rate of chemical reactions, while precipitation can enhance chemical weathering by providing water for reactions and mechanical weathering by contributing to erosion. Vegetation can impact weathering by producing acids that enhance chemical weathering and by roots that can cause mechanical weathering. Human activity like construction and mining can accelerate both chemical and mechanical weathering processes.
The two main types of weathering are mechanical (physical) weathering and chemical weathering. Mechanical weathering involves the physical breakdown of rocks into smaller pieces, while chemical weathering involves the alteration of rock materials through chemical reactions.
Mechanical weathering breaks down rocks into smaller pieces, increasing their surface area exposed to chemical weathering agents like water and acids. This increased surface area allows for more efficient chemical reactions to occur, accelerating the chemical weathering process. Additionally, mechanical weathering can create fractures and cracks in the rock, providing pathways for chemical weathering agents to penetrate deeper into the rock, further enhancing the weathering process.
Acids in the rain create holes in the rock, which allows water to get inside for ice wedging.
A waterfall is formed by chemical weathering. Chemical weathering is a process by which a decay of rock is caused by oxygen, hydrogen and some mild acids to produce rock formations.
Mechanical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, usually through processes like freeze-thaw cycles or root wedging. Chemical weathering, on the other hand, alters the chemical composition of rocks through reactions with water, oxygen, or acids, resulting in the dissolution or breakdown of minerals. Both processes work together to break down rocks and contribute to the overall weathering of Earth's surface.
The vegetation source of weathering is the organic acids released by plants as they decompose. These acids can break down minerals in rocks, leading to weathering processes such as chemical weathering. The roots of plants can also physically break apart rocks, contributing to mechanical weathering.
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
