Erosion And Transportation Flashcards
What is hydraulic action
It is when air and water force open cracks in rocks by pressure
What is attrition
It is when rocks hit against each other creating pebbles and fragments of rocks
What is abrasion
It is when rocks are hurled by the waves at the banks or cliff
What is corrosion
It is when acid mixes with the water and erodes the rocks
What are the four types of transportation
Solution, suspension, traction, saltation
What is suspension
It is when fine material is suspended in the river
What is solution
It is when materials are dissolved in the river
What is saltation
It is when rocks bounce along the river bed
What is traction
It is when rocks are rolled along the river beds
What is longshore drift
It is when the wind and the waves move sand along a beach
What are the four types of erosion
Hydraulic action, corrosion, abrasion, attrition
