Waves form when wind blows over open stretches of water, causing water particles to move up and down in orbit rather than the water itself moving. When waves reach the coast, they can have either constructive or destructive impacts. The document instructs students to define key terms like fetch, beach, and crest; diagram what happens when waves reach the coast; and create a guide for surfers explaining how waves form and the different types of waves.

4. How do waves form and how do they
impact the coastline?
• Waves form when the wind blows over a
stretch of water.
• It is important to remember that the water
itself does not move from one side of the
ocean to the other, with the waves, but
water particles just move up and down in an
orbit.
