Flashcards in The Sea Deck (8):
When the water runs out of speed it stops and it flows back down the beach towards the sea.
-have a strong swash = transports and deposites material on the beach
-weak backwash = doesnt carry much material back to sea
-add material to the beach
-strong backwash = wears away & carries material from the beach
- -> a lot of erosion & destroy/destruct the coastline
This is the power of the watter hitting the coastline
The waves trap air in cracks in the rocks. As the waves retreat the trapped air expands quickly and can crack the rock.
Is the erosion caused by small rocks carried in the sea water hitting against the coastline
Is the erosion caused by the small stones hitting eachother breacking themselves into smaller pieces
