3-5 waves
The energy in waves comes from wind that blows across the water's surface.
DID YOU KNOW... Large ocean waves are the result of powerful thunderstorms out in sea.
When a wave hits land, the sediment wears away rock like sandpaper wearing away wood.
Waves shape the coast through both erosion and deposition.
LONGSHORE DRIFT~~ Angled waves create a current that runs parallel to the coastline. As repeated waves hit the beach, sediment moves down the beach with the current, in a process.
SPIT~~ A beach that projects like a finger out into the water.

key ideasThe energy of ocean waves comes from wind blowing across the water's surface and transferring energy to the water.
Ocean waves hitting land cuase erosion through impact and abrasion. Waves also move and deposit sediment along the shore. |

checkpoint questionsWhat are two of the processes by which waves can cause erosion?
How can waves produce a cliff on a rocky coast? |
section questions1. How do ocean waves form?
2. Desribe two landforms created by wave erosion and two landforms created by wave deposition. 3. Why are headlands eroded faster than the land at the ends of inlets and bays? 4. Thinking Critically Predicting You visit a rocky headland by the ocean that has a sea arch and several sea stacks. How might this area change in the next 500 years? |
