Compare and contrast mechanical weathering and chemical weathering?

Answer 1

Mechanical weathering provides fresh surfaces for attack by chemical processes, and chemical weathering weakens the rock so that it is more susceptible to mechanical weathering.

Answer 2

Physical and chemical weathering all involve the same thing - the wearing down of an object. Physical weathering include wind and sand that works like a sand blaster to wear down rocks. Chemical weathering include corrosion and acid rain.

Answer 3

The differences are that mechanical weathering is the breaking of rock into smaller pieces by forces due to gravity, corrosion, freezing (dilatation of the material) and melting of water, plant roots, or other forces. (The mechanical does it physically)

So then chemical weathering is the changing of materials in a rock by chemical processes, for example acidic rains action, solubility of some components, chemical reactions, thermal decomposition, etc.

Answer 4

Mechanical weathering simply breaks big rocks into smaller rocks. Chemical weathering dissolves rocks and changes them chemically.

Answer 5

mechanical weathering is not changed chemically.

Answer 6

Chemical weathering has acid rain while mechanical weathering doesn't.

Chemical weathering is also called physical weathering. The U.S.A. has mechanical weathering.

Answer 7

that they both brake rocks and minerals into different ones

Answer 8

They both reduce the size of a rock body.
