Is mechanical weathering a crack in the sidewalk?
Mechanical weathering refers to the physical breakdown of rocks into smaller fragments without changing their chemical composition. It can indeed contribute to cracks in a sidewalk over time, especially in areas with temperature variations leading to freezing and thawing cycles.
Is water freezing in cracks in rocks physical or chemical weathering?
Water freezing in cracks in rocks is a physical weathering process. As water expands when it freezes, it exerts pressure on the rock, causing the cracks to widen and eventually break apart. This process is known as frost wedging and is a common form of mechanical weathering.
When a tree cracks a sidewalk is it weathering?
No. Weathering is the action of sun, rain, wind altering the color, texture, composition, or form of exposed objects.
Is ice wedging physical weathering or chemical weathering?
Ice wedging is physical weathering. As water freezes it grows, so when water flows into cracks or holes and then freezes it causes the water to expand, which brakes apart whatever it seeped into.
What type of weathering is crack in the sidewalk?
if its near a tree then the roots of the tree make the sidewalk crack. i am in sixth grade and i know this! You are dumb, it would be mechanical weathering.
How does physical weathering make the job easier for chemical weathering?
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.

How does physical weathering cause chemical weathering to be more effective?
by helping each other by breaking down the minerals

Explain whether water is a cause of either chemical weathering physical weathering or both?
Water can cause both chemical and physical weathering. In chemical weathering, water can react with minerals in rocks to break them down into new substances. In physical weathering, water can seep into cracks in rocks, freeze, and expand, creating pressure that breaks the rock apart.
Is moss physical or chemical weathering?
Moss does not directly cause physical or chemical weathering itself. However, moss can indirectly contribute to chemical weathering by producing organic acids that can break down rocks over time. Additionally, moss can also contribute to physical weathering by helping to break apart rocks as their roots grow into cracks and crevices.
How can physical weathering increase the rate of chemical weathering?
Physical weathering breaks rock down into much smaller pieces and gives the original rock a much greater surface area which, when exposed to chemical agents such as carbonic acid, reacts at a much faster rate than it would had the larger rock not undergone physical weathering.
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 are the 2 main types of weathering?
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.
