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 only occur on small surfaces, not large ones.
D) Chemical weathering requires salt, which is provided by salt wedging.
