What type of weather is water weathers?

If you meant weathering that is caused by water; physical weathering is the answer.


What are 2 factors that affect the rate of weathering?

The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.


One type of physical is caused by the wind?

Which of these type of weathering does not require the presence of water?

Since you did not specify which types of weathering you meant (necessary for this question to properly be answered), I will just summarize a bit of basic information on weathering and try to answer as best as I can in the most general sense.There are three general types of weathering: mechanical (sometimes called physical), chemical, and biological. Chemical weathering entails the alteration of the chemical and mineralogical composition of the weathered material. Physical weathering is the breakdown of mineral or rock material by entirely mechanical methods. Biological weathering involves the disintegration of rock and mineral due to the chemical and/or physical agents of an organism.Chemical types can be caused by processes that require water (such as hydrolysis, or carbonation - when there is formation of carbonic acid from carbon dioxide and water). Physical types contain processes that may not, though. For example, a type of physical weathering is abrasion, which is when there are collisions that can be caused by wind (although it can also be caused by water or ice). Sometimes biological weatheringdoes not require water - such as when particles fracture because of animal burrowing or due to pressure being exerted by growing roots.


Coastal regions are often affected by abrasion what processes would cause increased abrasion along a coastal region?

Rising sea levels and storm force winds would be good examples of processes which would cause increased abrasion along a coastal region.
