How do wetlands protect shorelines from erosion

Why does physical weathering speed up the processes of chemical weathering? a) physical weathering requires abundant water, as does chemical weathering. b) physical weathering produces fresh surfaces for chemical weathering to attack. c) chemical weathering can occur only on small surfaces, not large ones. d) chemical weathering requires salt, which is provided by salt wedging.

Explain: plate tectonics and people.

What is an additional type of erosion found at the coast? what does it mean?
