Mechanical Weathering
A type of Chemical weathering that happens when water interacts with minerals.
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
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.
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock

The type of weathering that causes Ice Wedging is Mechanical/ Physical Weathering.
Ice wedging is a form of mechanical 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.
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.
If the crack has enlarged as a result of the freezing water, it is an example of a type of physical weathering known as ice wedging.

an example of mechanical weathering is called ice wedging. it is when water gets into a small crack in rock then freeze and expand breaking the rock.
