- Destructive interference
- High Tides
- Wave crest
- a The subtraction of wave energy as waves meet producing smaller waves.
- b These boundary currents move warm water from the equator towards the poles.
- c highest part of a progresive wave
- d High water position corresponding to a tidal crest
- e Eddies do not tend to form in these boundary currents.
5 Multiple choice questions
- These waves are the first to form when the wind blows.
- Waves with a ratio greater than 1:7 will do this.
- These waves have a wavelength greater than 1.73cm. The restoring force is gravity and momentum. Wind waves are one example of these waves.
- surface winds drive surface currents, and each layer of water drags the layer below, but the Coriolis Force changes each layer's direction slightly to make a spiral effect
- This type of tidal cycle is found commonly in the Gulf of Mexico.
5 True/False questions
Long → Surface currents are powered by the sun and ______________
Plunging Wave → A wave that surges ashore without breaking.
Western → These are the fastest flowing boundary currents.
Equator → Due to the warmth of the water, the molecules are slightly expanded in this region.
Eastern → There are five of these boundary currents. They carry cold water towards the equator.
