- Wind Strength
- a The length of time the wind blows, the fetch and this are three factors that affect wind wave development.
- b Which direction do gyres flow in the Northern hemisphere?
- c the regular rise and fall of the ocean's surface influenced by the moon's gravity pulling on earth
- d Eddies do not tend to form in these boundary currents.
- e Nearly friction free transfer of energy from molecule to molecule in a circular path.
5 Multiple choice questions
- a wave in which water oscillates without causing progressive wave forward movement. there is no net transmission of energy in a standing wave
- Maximum ratio of wave height to wavelength seen in the open ocean. Also known as wave steepness.
- Gyres in balance between gravity and the Coriolis Effect.
- Waves transmit _______________.
- These waves tend to be less than 3m high, and have wavelengths between 60 - 150m in the ocean.
5 True/False questions
Eastern → The Gulf Stream is an example of this type of boundary current.
Semidiurnal → Eddies do not tend to form in these boundary currents.
Gyre → Circular flow pattern of water caused by deflection of water by continents and the ocean basin.
Counterclockwise → Which direction do gyres flow in the Southern hemisphere?
Wave Frequency → The reflection of progressive waves by a vertical barrier. Reflection occurs with little loss of energy.
