When two rocks rub up against each other, pieces of the rock wear away. This is called abrasion.
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.
The other cause of mechanical weathering is abrasion, which occurs when rocks are worn down by friction from other rocks or sediments. It involves the breaking and wearing away of rock surfaces through the mechanical action of other rock or sand particles.
The breakdown of rocks due to wind is an example of physical weathering. As the wind blows sand and other particles against the rocks, it can cause them to erode and break apart over time. This process of mechanical weathering contributes to the gradual reshaping of the Earth's surface.
Physical weathering, such as frost wedging or abrasion, can cause a reduction in the size of bedrock regolith mineral particles without changing their chemical composition. This type of weathering does not alter the minerals themselves, but only breaks them down into smaller fragments.
it cracks a rock by the roots reaching it and the longer you wait, the more it will crack until it finally just brakes
Earthworms tunnel through the soil and move soil particles around. The motion breaks some particles into smaller particles. It also exposes fresh surfaces to continued weathering.

No, acids cause chemical weathering.
Yes, mechanical weathering.
Temperature changes, such as freezing and thawing, is NOT a cause of mechanical weathering.
Mechanical.

It is the digging, scurrying, clawing, tunneling, walking, scratching. They are enough to cause the breaking of rock into smaller particles.
