Question 3

Why does the beach slope under water become steeper near shore?

Accepted Answer

A) The sand grains are finer near shore. 
B) The bottom has to rise rapidly to merge with the sand of the barrier island. 
C) Sand from the onshore part of the beach has to drop abruptly because offshore the sand is under water. 
D) Waves in shallow water drag on the bottom, so they lose energy and need a steeper slope to move the sand. 
E) The waves are bigger near shore.

Question 10

Why can non-native plantings on dunes be counterproductive in protecting beaches?

Accepted Answer

A) Non-native plants rarely survive in beach environments. 
B) Non-native plants can require artificial watering, leading to a rise in the water table and gully formation. 
C) Non-native plants can block the wind from moving the sand to and from the dunes. 
D) Non-native plants can overtake the dunes, covering most of the sand, and require frequent cut-back. 
E) Non-native plantings can change the soil acidity, making the sand more likely to blow away.
