The size of oceanic waves is a function of the velocity of the wind and of fetch, the length of the surface of the water subject to those winds. The impact of waves against a coastline is a function of the size of the waves and the shape of the sea bottom. The degree of erosion to which a coastline is subject is a function of the average impact of waves and the geologic composition of the coastline.
If these statements are true, which one of the following must also be true?
(A) The degree of erosion to which a coastline is subject is related to the shape of the sea bottom.
(B) The size of oceanic waves will not fluctuate far from an average for any given stretch of ocean.
(C) The fetch of winds is related to the shape of the sea bottom.
(D) The size of oceanic waves is related to the shape of the sea bottom.
(E) The average velocity of the wind in an area plays no role in the degree of erosion to which a coastline is subject.

Given that, size is a function of velocity and fetch, impact is a function of size and shape, erosion is a function of impact and composition.
A. since erosion is a function of impact and impact is a function of shape. So, erosion is a function of shape. True.
B. contradicts size is a function of fetch. False.
C. impact is related to size and consequently to fetch doesnt mean shape will be related to fetch. False
D. impact is related to size and shape doesnt mean size and shape will also be related. False
E. erosion --> impact --> size --> velocity. so the relationship exists. False.

The degree of erosion to which a coastline is subject is related to the shape of the sea bottom, erosion depends on fetch and shape of the sea bottom. so s should be true
