When water freezes and becomes into ice, it expands. Imagine this inside the crack of a rock. Evidently the crack will only enlarge too. After freezing and thawing so many times bits of the rock break off.

How can trees and other plants cause weathering?

they cause it by their roots growing into rocks and breaking up the rocks. After the rocks have been broken up by trees and plants' roots, water and air will wash it away, and eventually dissolve it.


How do trees and grass weather rock?

What of these does not cause physical weathering?

Chemical weathering does not cause physical weathering. Chemical weathering refers to the breakdown of rocks through chemical reactions, while physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.


What is the main cause of rocks weathering?

How do acids in groundwater cause chemical weathering?

It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.


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.


Why do many rocks become rounded?

Erosion and weathering will cause rocks to become rounded.


Can weathering have an effect of the breaking down of rocks?

Yes, weathering can break down rocks through physical or chemical processes. Physical weathering can occur through freezing and thawing, while chemical weathering can happen through reactions with water, oxygen, or acids. Over time, these processes can cause rocks to crumble or dissolve into smaller fragments.


Do mountain rocks cause chemical or mechanical weathering?

Mountain rocks can undergo both chemical and mechanical weathering. Mechanical weathering breaks rocks into smaller pieces through physical processes like frost wedging and abrasion. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution, which can alter the composition of the rock.


What does weathering cause?

weathering results in the disintegration of rocks on a large scale. then these rocks break-up and forms soil and the soil forms the soil profile.
