B and C E all of the above

Explanation / Answer

9) A- waves are refracted

Waves travel slower in shallower water (just like light travels slower in glass than in air), and so the distance between waves gets shorter when the waves enter shallower water. If the waves enter shallower water at an angle with the beach, then the part of the wave closer to the beach slows down and the rest of the wave catches, turning the wave into the beach.

10) A- exhibites a wide beach berm .

A summer beach has a wide, well-developed berm often with a vegetated dune where American beach grass grows seaward onto the berm. A winter beach is lower, may not have a berm, and often shows signs of loss of beach grass.

11) D

cyclicity and equilibrium or balancing change

12) A- sand is transported parellel

sand carried by the current of longshore drift and deposited at a less turbulent part of the current. Thus, they most commonly occur across artificial bay and river entrances due to the loss of kinetic energy in the current after wave refraction.
