    • abrasion is the action of rocks hitting up against a cliff and breaking bits off
    • solution is small pieces of rock dissolved in water
    • attrition is rocks in the water hitting agaisnt eachother and breaking down
    • hydraulic action is water pushed into cracks in rocks and breaks them apart
    • biological weather is living things weakning rocks
    • chemical weathering is chemicals dissolving in sea water and breaking rocks, like acid rain
    • physical weathering is water falling into cracks of rocks and then it freezes, expands, and then weakens the inside of the rock
    • traction is when rocks are rolled along the sea bed
    • saltation is when rocks are bounced and lifted along the sea bed
    • solution in transportaion is when disolved sediment is carried
    • suspension is when rocks are carried through the water
    • the 4 types of erosion are, abrasion, attrition, solution and hydrauliuc action
    • the 4 types of transportation are , traction, saltation, suspension and solution
    • the types of weathering are biological, chemical and mechanical/physical
