TIDES
GRAVITY from the MOON'S INFLUENCE
What do researchers say are responsible for TIDES?
Measurement of a wave's height.
What is the vertical distance between a wave's CREST and its TROUGH?
Ocean navigation
What types of things do CURRENTS affect?
Lunar Tides
What are the larger types of tides produced by?
Thermohaline currents
Two Lows and Two Highs
How often do TIDES happen in a 24 hour period?
Wave HEIGHT
What is affected by WIND SPEED, FETCH, and WATER DEPTH?
The climate of large areas of the world
What do the currents in the ocean have an effect on?
High and Low Tides
What is produced by the earth moving under a TIDAL BULGE?
Surface currents
What runs in the SAME direction as global winds?
Small projects and virtually waste free.
What are TIDAL POWER PLANT GENERATION PROJECTS?
Wave BASE
What is the deepest point of a wave below the surface of the water?
Currents that move eastward and westward
What is the CORIOLIS effect?
Coastal Stacks
What are the LAST REMNANTS of a SEA ARCH called?
Water moves in very short distances.
How far do WAVES make water move?
Tides
What do we NOT see or observe in the open ocean?
Wave PERIOD of time.
What is the time it takes for two successive crests (one wavelength) to pass a specified point?
Water forced downward has more oxygen but less nutrients.
What does DOWNWELLING do to the ocean water?
Beaches with coarser sand
What kind of beach has a very steep angle?
Building "groins or jetties" type of structures capture sand that is transported by the longshore current.
How can WAVE EROSION be reduced?
Solar Tides
What type of tide produces the smallest obersvable tides?
Wave SPEED
What is most directly related to the WAVE TIME PERIOD?
What does DOWNWELLING, EKMAN SPIRAL EFFECT, and DENSITY DIFFERENCES have the MOST effect on?
Tidal power generation
What kind of energy or power source is plentiful and potentially driven by gravity?
Ekman Spiral
What explains the deepest current changes in the ocean?
