Chemical - solution
water dissolves minerals then removed in solution
1 of 9
Chemical - oxidation
oxygen dissolved in water and reacts with minerals
2 of 9
Chemical - hydration
rocks expand due to water entering, causing stress
3 of 9
Mechanical (physical) - hydration
rocks expand due to water entering, causing stress
4 of 9
Mechanical (physical) - wetting and drying
the expanding and contraction causes rock to disintegrate
5 of 9
Mechanical (physical) - frost shattering
cycles of freezing and thawing cause rocks to shatter
6 of 9
Mechanical (physical) - insolation weathering
expansion from heat and contraction from less heat cause peeling
7 of 9
Mechanical (physical) - crystal growth
high temps draw saline groundwater to the surface, the water evaporates, causing salt crystals to grow between pores and joints, thus causing granular and block disintegration
8 of 9
Biological
very little due to few plants/ animals due to aridity
