ice wedging
frost wedging
Biological hydraulic weathering.
ice wedging/frost wedging, pressure release, plant root growth, abrasion.
Scree or talus would typically be formed by weathering due to ice wedging, plant root growth in rock crevices, pressure release, tensional stress, or compressional stress.
No. Root wedging is a form of mechanical weathering.
physical
The growth of tree roots is chemical, wedging(?), pushing thru the ground(?), would be a physical change.
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.
they are both a type of physical weathering and both may break rock through a crack or a crevice. Frost wedging is when water enters a crack and may freeze causing the crack to expand because when water freezes it contrasts and expands. Root wedging is when a plant grows through a crack causing the roots to expand and break through the rock. -michael yap
The process is called mechanical weathering. It involves the breakdown of rocks into smaller fragments through physical processes such as frost wedging, root action, and abrasion, without altering the chemical composition of the rock.

Frost wedging is classified as mechanical weathering, but does open up rock to further surface attack by chemical weathering.
