The wearing away of something by different processes.
What are the types of erosion?
Hydraulic action
Abrasion
Attrition
Solution
What is Hydraulic action?
Where waves enter cracks in rocks, air is compressed by the force of the water causing erosion and forming features such as blowholes.
What is abrasion?
The grinding away of rock by other rock particles carried in water, ice, or wind. Like sandpaper.
What is a solution?
A mixture that forms when one substance dissolves another.
What is attrition?
Where rocks are bashed against each other and eventually form round rocks.
What is corrasion?
The effect of rocks being flung at the cliff by powerful waves.
What are the 4 types of sediment Transportations?
Traction
Saltation
Suspension
