EARTH PROCESSES CONCEPT PROJECT

By Spencer Hackworth

Concepts1. Beaches being made depend on wave

energy, sediment supply, the tides and seasons, and the weather.

2. A jetty, breakwater, and seawalls are all land formations used to lessen erosion and deposition of the beach.

1st Concept Description The energy of the waves push the

deposited soil into the beach therefore expanding the beach. The sediment supply is the deposited soil that expands the beach. The soil is essential to the beach. Depending on how big the tides are is important because the beach will either erode or pile up. The weather effects the tide which means the beach will be eroded. There are many natural processes that effect the beach.

2nd Concept Description Jetties are horizontal breakers made of

rock that lessen erosion and help the beach to grow. Seawalls are not man made and are natural. Somehow mother nature knew that they would help to reduce erosion and deposition. The two landforms really help the beach to live. A seawall is made of rocks and a jetty isn’t but they both seem to work.
