1. What area is considered the shore? The shore is the area between high and low tide. Th

e area where the land meets the ocean.

2. Describe the type of area that is required for a beach to form. For a beach to form, there n

eeds to be a sheltered environment, like a bay. A bay forms when rock (relatively soft) is

eroded. There are pieces of land sticking out called the headlands, which are made up o

f harder rocks. Another area is the swash, which is the incoming wave of water, is strong

waves that approach at an angle to the shore but then the swash recedes directly away

6. What artificial barrier do humans use to protect the coast from high tide? Rocks are pl

aced above the high tide limit. These rocks are not natural, they are called a riprap.
