| Question | Answer |
|---|---|
| What are the main two parts of waves? | Crests and troughs. |
| What is the highest part of the wave? | Crest. |
| What is the lowest part of the wave? | Trough. |
| What is the distance between two adjacent wave crests or troughs? | Wavelength. |
| What is the vertical distance between the crest and the trough of a wave? | Wave Height. |
| What type of movements to ocean waves make? | Circular. |
| What is the time between the passage of two wave crests? | Wave Period. |
| wavelength (m) = wave speed (m/s) wave period (s) |
Formula for calculating wave speed. |
| What are some examples of things that cause waves? | Wind, earthquakes, landslides, and impacts of cosmic bodies. |
| What are waves that move in water deeper than one half their wavelength? | Deep Water Waves. |
| When waves reach water shallower than one half their wavelength and then begin to interact with ocean floor, they are called? | Shallow Water Waves. |
| What are the stages of the life span of a wave? | Deep Water Waves Shallow Water Waves. Breakers in the break zone. Surf on the shore. |
| Gravity eventually pulls high wave crest down, which causes waves to tumble downward forming ___________________. | Breakers |
| The area where wave first break is called the _______________________. | Break Zone. |
| What is the area between the breaker zone and the shore? | Surf |
| What is a subsurface current that is near shore and pulls objects back out to sea? | Undertow. |
| What is the water current that travels near and parallel to shoreline? | Longshore Current. |
| What are white foaming waves with very steep crests that break in the open ocean before the waves get close to shore? | White Caps. |
| What are rolling waves that move steadily across the ocean. They have longer wavelengths than white caps and can travel further? | Swells. |
| What are waves that form when a large volume of ocean water is suddenly moved up and down such as by earthquake? | Tsunamis. |
| What is a local rise in sea level near the shore that is caused by strong winds from a storm or hurricane? | Storm Surge. |
