Coastal Processes Flashcards
1
Q
Abrasion/Corrasion
A
Rock fragments thrown against the headland create a sandblasting (abrasive) action, wearing away the rock.
2
Q
Hydraulic Action
A
Pounding waves compress trapped air in the rocks, creating an explosive blast which weakens and loosens rock fragments.
3
Q
Solution/Corrosion
A
Carbonic acid in sea water weathering limestone and chalk.
4
Q
Attrition
A
Rock fragments slowly being ground down by friction from wave action into smaller and rounder pieces to form sand.
