Physical (mechanical) weathering occurs when a rock is broken into smaller pieces without a change in chemical structure. Abrasion, fracture by freezing, plant root growth expansion of fractures, rock falls; these are forms of physical weathering.

∙ 11y agoThe most common type of mechanical weathering takes place when water freezes to ice in a crack in the rock. Because water expands when it freezes, the ice widens the crack and eventually splits the rock. This process is known as frost wedging.

In what type of weathering does salt wedging occur?
mechanical weathering
How does weathering change minerals?
Physical or 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.
Can you give me some notes about weathering?
There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.

When does weathering occur?
There are two types of weathering that occur: chemical weathering and physical weathering. One example of physical weathering is crushing a rock with a hammer. An example of chemical weathering is acid rain where the material is chemically broken down because of the rain's acidity.
