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