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.
Physical weathering can enhance chemical weathering by increasing the surface area available for chemical reactions to occur. This is because physical weathering breaks down rocks into smaller pieces, exposing more surface area to chemical processes like oxidation and hydrolysis. So, physical weathering does not inhibit chemical weathering; instead, it can actually facilitate it.
The process of breaking igneous rocks into smaller pieces is called weathering. This can occur through physical weathering (such as frost wedging or abrasion) or chemical weathering (such as dissolution or hydrolysis).
Is chemicals from plants chemical weathering or physical weathering
Mechanical weathering. It refers to the breakdown of rocks into smaller pieces without altering their chemical composition. This can occur through processes such as frost wedging, abrasion, and root wedging.
Physical or mechanical weathering
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.
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.
Physical weathering is most likely to occur in climates with frequent temperature changes, such as in deserts and mountainous regions. These areas experience daily temperature fluctuations that contribute to the expansion and contraction of rocks, leading to physical weathering processes like freeze-thaw cycles and exfoliation.

Physical weathering can occur at varying speeds depending on factors such as the type of rock, climate, and environmental conditions. In general, physical weathering tends to be a slow process compared to chemical weathering, as it involves physical forces like wind, water, and temperature changes breaking down rocks over time.
it is physical weathering
No weathering is not the same as physical weathering.Kayla
Four types of weathering that can occur without water include mechanical weathering caused by temperature changes, chemical weathering due to oxygen in the air, biological weathering from plant roots and burrowing animals, and physical weathering caused by wind abrasion.
how are physical weathering and chenical weathering alike and different
Physical weathering breaks big rocks into little rocks and increases the surface area exposed to chemical agents, such as carbonic acid. The more the surface area, the faster the weathering.

physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
