Alternating wetting and drying, causing continuous heating and cooling of rock surfaces, due to change in weather conditions by rainfall and sunshine periods, which leads to uneven expansion within rock layers. This eventually results in cracking and peeling off of rock surfaces (exfolliation).
frost action, hydrolysis, thermal expansion or unloading
It exposes bedrock to the forces of chemical weathering.
Abrasion
Frost action
water
Frost wedging.
The mechanical weathering involves erosion,wind pressure.
frost wedging ?
it is found in a desert

Frost wedging.
Freezing and thawing.
well it is very hard to break up bedrock, but the main process that does is weathering. You have two seperit kinds of weathering. The first one is Chemical Weathering. Chemical weathering is when weathering effects the exterior. two examples are rust and leaching. The second type of weathering is Mechanical Weathering. This effects rocks physically. two examples are abrasion and erosion.SO THE MAIN ANSWER WOULD BE WEATHERING. THE TYPE OF WEATHERING, MECHANICAL WEATHERING, THE PROCESS, ABRASION (well there is more than that but that is the most common situation)
The mechanical weathering involves erosion,wind pressure.
Climate & Moisture
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
Mechanical weathering
Colder climates can help this process. It can also depends if it is a wet or dry climate.
Chemical weathering in the warm, wet season and mechanical weathering in the cool, dry season.
