A
B
It is a type of sediment movement where grains of sand are bouncing along the river bed.
Solution
Suspension
Traction
Saltation
The outer layer of rocked subsequently peel off from its main mass due to the removal of pressure from the overburden.
Hydration
Exfoliation
Frost Wedging
Thermal Expansion
Which is an example of oxidation?
Some of the minerals get disolved in water.
Rust decomposes rocks completely with passage of time.
The joints enlarge in size and lime is removed in solution.
Due to absorption of water by rock, its volume increases and grains lose their shape.
It is a process that breaks down rocks and eventually transformed into sediments.

What type of weathering involves when trees put down roots through joints or cracks in the rock in order to find moisture. As the tree grows, the roots gradually prize the rock apart?
Biological Weathering
Abiotic Weathering
Chemical Weathering
Mechanical Weathering
Its a type of erosion that commonly occurs in flat, bare areas or dry, sandy, and loose soils.
