1)What is the direction of the longshore current at A. The waves are coming in to the shore from the southeast, as indicated by the arrow.

a)In this example, no longshore current is created

b)The longshore current is moving from the upper right to the lower left.

c)The longshore current is moving from west to east.

d)The longshore current is moving from the lower right to the upper left

2)Storms on the ocean create huge waves that travel for thousands of miles. What would be the net motion of a particle of water in one of these huge waves, if the wave moves at a speed of 20 meters per second for a time of one minute. The wavelength is 50 meters and the amplitude is 3 meters.

a)600 meter

b)120 meters

c)0 meters

d)60 meters

3)Waves can cause a large amount of erosion as well as abrasion, especially when the water is loaded with sand and other sediments. However, even clean water (no sediments) can cause erpsion through a process called

a)cavitation

b)swash

c)backwash

d)sublimation
