Coastal Processes Flashcards
What is the process hydraulic action?
Impact of the rocks from the force of water. Results in weakening rock surface.
What is the process of wave quarrying ?
Breaking wave traps air as it hits the cliff face.
Force of water compresses this air in any gap in the rock face.
Results in enormous pressure within the fissure or joint.
As water pulls back, results in explosive effect of air under pressure being released.
Can over time weaken the cliff face.
What is the process of abrasion?
Material being picked up by the sea, hitting off rocks and cliffs causing it to wear away.
What is the process attrition?
The rocks in the sea which carry out abrasion are slowly worn down into smaller and more rounded pieces.
What is the process solution?
The process of solution included the dissolving of calcium based rocks, for example limestone being carried along by the river.
