it cracks a rock by the roots reaching it and the longer you wait, the more it will crack until it finally just brakes

What type of weathering does plant cause?

Plants can cause mechanical weathering by growing into cracks in rocks and breaking them apart as their roots expand. They can also cause chemical weathering by releasing acids and other compounds that break down the minerals in rocks.


Animal burrows dug in rock that let in water and air chemical or mechanical?

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.


What processes can cause rock to breakapart into sediment?

Weathering processes such as mechanical (physical) weathering, chemical weathering, and biological weathering can cause rocks to break apart into smaller pieces or sediment. Mechanical weathering includes processes like freeze-thaw cycles, abrasion, and root wedging. Chemical weathering involves reactions with water, oxygen, and acids that dissolve or weaken rock minerals. Biological weathering results from the actions of plants, animals, and microorganisms that break down rocks through physical or chemical means.


What are the differences between mechanical weathering and biological weathering?

Mechanical weathering involves the physical breaking down of rocks into smaller pieces without changing their chemical composition, such as through frost wedging or abrasion. Biological weathering, on the other hand, is the breakdown of rocks by living organisms like plants and burrowing animals, which can weaken rocks through root growth and acidic secretions.


What is called when rocks break down without changing in chemical composition?

Mechanical weathering.
