Waves And Tides Flashcards
Tides are caused by:
The gravitational pull of the moon and the sun
Neap tides are when the tidal range is:
At its lowest.
Neap tides occur at what stage in the lunar cycle?
At quarter moons
Spring tides occur at what stages in the lunar cycle?
At the new moon and the full moon
What celestial body has the greatest effect on tides?
The moon
The Fundamental Equilibrium Tide model is:
A theoretical model in which all landmass is
removed from the earth and friction between
the seafloor and the water is removed.
Spring tides are when the tidal range is:
At its highest.
Waves that move freely on the ocean
surface are called:
Progressive waves
Forces that return the ocean surface
to its normal configuration are called:
Restoring forces
The path of a water molecule in a progressive
wave is best described as:
A circular orbit in the direction of the wave
with only a slight net forward movement.
Waves that are static at intervals and oscillate
vertically in between those points are called:
Standing waves
Standing waves are caused when a
vertical barrier is located at ______.
The crest or trough
Wave height is determined by 3 factors. These are:
Wind speed, wind duration, and fetch
Fetch is defined as:
The distance over water that wind blows
in a single direction.
A point of almost zero tidal fluctuation
on the ocean surface is called:
an Amphidromic point
