Question 13

Why does sea level rise during a near-shore storm?

Accepted Answer

A) Low atmospheric pressure of the storm permits sea level to rise. 
B) The winds stir the water in circles, so it rises in the center. 
C) High pressure in the storm forces the water up.

A) atmospheric pressure 
B) wind speed 
C) fetch 
D) amount of time the wind blows across water 
E) interaction with other waves of different sizes and speeds

Question 15

What happens to wave energy and erosion when riprap or seawalls are installed?

Accepted Answer

A) Waves striking the riprap are reflected back against the incoming waves to lessen their overall effect. 
B) Wave height rises against the wall, and more erosion occurs at the base of the wall. 
C) Seawalls do not influence wave energy or erosion; they only create separation between the sea and structures. 
D) Waves lose their energy against riprap or seawalls, so erosion is prevented in that area. 
E) Waves pulverize the riprap and seawalls, creating sand that helps maintain the beach.
