Frost shattering:
Water enters ( cracks, burrows, structures ), joints and bedding planes.
In climates where daily ( temperatures, pressures, windspeeds ) fluctuate above and below ( 0oC, 5oC, -2oC ), water freezes and expands by ( 9%, 7%, 12% ).
This exerts ( pressure, force, tension ) on rocks, producing a residue of angular fragments called ( scree, shards, breccia ).

Pressure Release:
Atmospheric at the Earth's surface is much lower than pressures within the Earth.
Pressure is released from rock due to of the rocks above them.
Rocks expand, producing which are more widely the they are from the surface.
Rocks that are well or have many bedding planes are affected.

Carbonation:
❌ gas in the atmosphere reacts with rainwater and ❌ water in the soil to form ❌ acid.
The air in pore spaces is rich in carbon dioxide due to decomposing ❌ litter.
This makes groundwater more acidic than rainwater which then reacts with ❌ minerals in the rock.

Clay particles require high velocities for erosion because they are ( flat, round ), ( platy, sheety, buldgey ) and ( cohesive, repellent ) so tend to stick together.
Clay particles remain in ( suspension, saltation, traction, solution ) even at low current velocities because they are ( small, medium, big ), have a ( low, high ) mass and are ( buoyant, gaseous ).
