Geo HW Flashcards
What is hydraulic action
it’s is when air gets into the cracks at the base of a cliff causing the cracks to expand fracturing the cliff
What is abrasion
The sandpapering effect when sediment rubs against the base of a cliff
What is traction
a method of transportation as the rocks ROLL along the bottom of the sea or river bead
What is attrition

What is biological weathering
Biological weathering is caused by the movements of plants and animals
What is chemical weathering

What is transportation
The process of transporting sediment from a beach to somewhere else
What is erosion

Solution
Where the water dissolves certain rock
Saltation
