Tides are caused by
Gravitational force exerted on Earth by the moon and sun.
100
Tide that occurs when sun and moon are aligned to give a maximum tidal range.
Spring Tide

The 3 factors that determine wave size are
Speed, Fetch, Duration
200
A tide just after the first or third quarters of the moon when there is the least difference between high and low water.
Neap Tide
200
Time for one full wave to pass a given point.
Wave Period

Describe a warning sign that a tsunami is approaching at the beach.
Water recedes abnormally
300
What causes deep ocean circulation?
Differences in water density (thermohaline circulation)
300
As a wave travels through water it transfers
Energy
300
A tidal pattern that is characterized by 2 Low Tides and 2 High tides of approximately the same height occurring within a day.
Semi Diurnal
300
The deflection of a moving obect (wind, water) to the right in the N Hemisphere and to the left in the S Hemisphere.

100 ft
400
How long is the wave length of the tidal wave(Bulge)?
1/2 Earth's Circumference
400
The term used to described a tidal pattern where 1 High and 1 Low tide occurs per day.
Diurnal
400
The name of tectonic boundaries where earthquakes are likely to form.
Subduction Zones

How does ocean circulation effect world climate?
Ocean circulation is responsible for moving heat throughout the world and therefore determines climate.
