What are the 4 types of errosion
Attrition
Abraision
Hydrolic action
Solution
What is Attrition
When waves make rocks crash together to make smaller and smoother pebbles
What is abraision
When waves break and sediments are thrown at the cliff
What is hydrolic action
When waves crash against cliffs and water fills in cracks which starts widening the cracks
What is solution
When weak acids slowly dissolve certain rocks because they include calcium carbonate
True or false:Attrition is when rocks clash together to make small smooth pebbles
True
True or false:Hydrolic action is when sediments are throw against the cliff
False
True or false:Solution is when water fills up cracks in the cliff which widens them
