- Capillary waves
- Wave reflection
- a These are the fastest flowing boundary currents.
- b These waves are the first to form when the wind blows.
- c The slowest moving waves.
- d The reflection of progressive waves by a vertical barrier. Reflection occurs with little loss of energy.
- e mature wind waves of one wavelength that form orderly undulations of the ocean surface
5 Multiple choice questions
- A breaking wave in which the upper section topples forward and away from the bottom, forming an air-filled tube.
- These boundary currents move warm water from the equator towards the poles.
- A high, often breaking wave generated by a tide crest that advances rapidly up an estuary or river.
- These waves travel though water deeper than 1/20 but shallower than 1/2 their wavelength
- Tide caused by gravitational and inertial interaction of the moon and Earth.
5 True/False questions
Eastern → These boundary currents move warm water from the equator towards the poles.
Ebb Current → Water rushing out of an enclosed harbor or bay because of the fall in sea level as a tide trough approaches.
1:7 → Maximum ratio of wave height to wavelength seen in the open ocean. Also known as wave steepness.
Spring → These tides are a time of greatest variation between high and low tides.
Neap → These waves move through water greater than 1/2 their wavelength.
