Chemical weathering Flashcards
1
Q

A
Chemical weathering changes the molecular structure of soil and rocks.
2
Q
Agents of Chemical Weathering?
A
Water, Oxygen, Carbon dioxide.
3
Q
What can Weathering occur through?
A
Solutions, Oxidation Carbonation Hydration Hydrolysis
4
Q
What is solution weathering?
A
A process where minerals or soluble chemicals in the rock dissolve directly in water.
5
Q
What is Hydrolysis?
A
A process where the minerals in the rock plus rainwater come in direct contact
6
Q
Hydration?
A
The process where the minerals from the rock absorb water and expand.
7
Q
Oxidation?
A
This process occurs when rock minerals react with dissolved oxygen to produce red or yellow oxides or hydroxides.
8
Q
Carbonation?
A
This process occurs when carbon dioxide dissolves in water to form a weak solution of carbonic acid.
