marine erosion Flashcards
1
Q
Hydraulic action
A
Waves crash rocks and compress the air in cracks - adding pressure.
repeated compression widens the cracks and causes the rocks to shatter
2
Q
Corrosion
A
water dissolves minerals from the rocks and washes it away
3
Q
Abrasion
A
Eroded water particles scrape and rub against the rocks - removing small pieces
4
Q
Attrition
A
Eroded particles in water collide with each other and break into smaller fragments
this causes their edges to become rounded off as they rub together
