- High Tides
- Slack Water
- a Gyres in balance between gravity and the Coriolis Effect.
- b There are five of these boundary currents. They carry cold water towards the equator.
- c lowest part of a progressive trough
- d High water position corresponding to a tidal crest
- e a time of no current, occurs at high and low tides when current change direction
5 Multiple choice questions
- This type of tidal cycle is found commonly in the Atlantic and Pacific Oceans.
- is the difference in height between successive high and low tides
- mature wind waves of one wavelength that form orderly undulations of the ocean surface
- A wave that surges ashore without breaking.
- A result of constructive and destructive interference that is seen on shore when waves do not all appear with a uniform size. Some are larger, some are smaller.
5 True/False questions
Clockwise → Which direction do gyres flow in the Northern hemisphere?
Capillary → Waves with a tiny wavelength less than 1.73cm. The restoring force is surface tension.
Neap → These tides occur when the earth, moon and sun are at right angles.
Wind Strength → lowest part of a progressive trough
Flood Current → Water rushing out of an enclosed harbor or bay because of the fall in sea level as a tide trough approaches.
