No. That is mechanical weathering. Weathering by sand or other matter carried in the wind is a special kind of mechanical weathering called aolean weathering. Weathering by acid rain is an example of chemial weathering. Limestone is particularly subject to this. Illegibility of tombstones in old garveyards provide a good illustration of this.
Chemical weathering involves the breakdown of rocks through chemical processes like oxidation, dissolution, and hydrolysis, rather than physical forces like wind, frost, and roots. Physical weathering, on the other hand, causes rocks to break apart through mechanical forces like temperature changes, ice formation, and plant roots.

Is freezing and thawing classified as chemical weathering or mechanical weathering?
Freezing and thawing is classified as a type of mechanical weathering, specifically known as frost wedging. This process occurs when water seeps into cracks in rocks, freezes and expands, causing the rock to break apart over time.
What process is not related to chemical weathering?
frost wedging
Is frost wedging an example of erosion?
Yes, frost wedging is a form of erosion. It occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart over time. This process is a common form of mechanical weathering that contributes to the breakdown of rocks.
How does chemical weathering promote mechanical weathering?
Chemical weathering weakens the minerals and rock materials, making them more susceptible to mechanical weathering processes like frost wedging or root growth. As the chemical bonds are broken down, the rock becomes more brittle and easily broken apart by physical forces. This combination of chemical and mechanical weathering can accelerate the breakdown of rocks and minerals.
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.
Is frost action mechanical or chemical weathering?
Frost action is a type of mechanical weathering. It occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.
Is frost wedging chemical weathering?
No, frost wedging is a physical weathering process, not a chemical one. It occurs when water seeps into rocks, freezes, and expands, leading to cracks and fractures in the rock. This repeated freeze-thaw cycle causes the rock to break apart over time.
How do mountains and rocks break apart?
They erode by the effects of wind and water
What weathering occurs when rocks are broken apart by physical processes?
Mechanical weathering occurs when rocks are broken apart by physical processes such as frost wedging, root wedging, or abrasion. These processes break down rocks into smaller fragments without altering their chemical composition.
What type of weathering is mountains?
Mountains are mainly shaped by mechanical weathering processes such as frost wedging, where water freezes and expands in cracks, causing rocks to break apart. Chemical weathering also plays a role, as rainwater and oxygen can react with minerals in rocks to break them down. Over time, these weathering processes contribute to the erosion of mountains.
What is a form of mechanical weathering?
Frost wedging is a form of mechanical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.
What is one weathering process that break rocks apart?
One weathering process that breaks rocks apart is mechanical weathering, which occurs when rocks are physically broken down into smaller pieces without any change in their chemical composition. This can happen through processes such as frost wedging, root wedging, and abrasion.
Is freezing and thawing classified as chemical weathering or mechanical weathering?
Freezing and thawing is classified as a type of mechanical weathering, specifically known as frost wedging. This process occurs when water seeps into cracks in rocks, freezes and expands, causing the rock to break apart over time.
Is frost wedging related to chemical weathering?
No, frost wedging is a physical weathering process caused by the expansion of freezing water in cracks and crevices of rocks. Chemical weathering involves the breakdown of rocks through chemical reactions rather than physical forces like frost.
What type of physical weathering is caused by the expansion of?
Frost wedging
What do you call a particular frost action which is an example of mechanical weathering?
The particular frost action that is an example of mechanical weathering is called frost wedging. This occurs when water seeps into cracks in rocks, freezes, expands, and ultimately causes the rock to break apart.
Frost wedging is an example of what?
Frost wedging is a type of physical weathering caused by repeated freezing and thawing of water in cracks of rocks. The expansion of water as it freezes helps to break apart the rock into smaller pieces over time.
