- a These waves move through water shallower than 1/20 their wavelength
- b Number of waves passing a fixed point per second.
- c Maximum ratio of wave height to wavelength seen in the open ocean. Also known as wave steepness.
- d Water rushing out of an enclosed harbor or bay because of the fall in sea level as a tide trough approaches.
- e Low water position corresponding to a tidal trough
5 Multiple choice questions
- These tides result in little variation in the height of tides.
- Surface currents are powered by the sun and ______________
- 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
- These are the fastest flowing boundary currents.
- There are five of these boundary currents. They carry cold water towards the equator.
5 True/False questions
Deep → These waves move through water greater than 1/2 their wavelength.
High Tides → Low water position corresponding to a tidal trough
Counterclockwise → Which direction do gyres flow in the Southern hemisphere?
Long → These waves tend to be less than 3m high, and have wavelengths between 60 - 150m in the ocean.
Wave diffraction → Bending of waves around obstacles.
