Name some of the factors that affect the movement of water within the world's oceans.

Read the following excerpt from the text. Select the sentence that explains why the Coriolis Effect differs how close you are to the equator.

The Coriolis effect is the result of Earth’s rotation. Because Earth rotates on its axis, any free-moving fluid on Earth is unable to travel in a completely straight line. In the Northern Hemisphere, all ocean and wind currents are deflected to the right by this effect. In the Southern Hemisphere, all currents are deflected to the left. This causes the curvature of ocean currents and prevailing winds. The Coriolis Effect is stronger at the equator, because Earth is rotating fastest there. Although the equator and the poles complete a single rotation in the same amount of time, a point on the equator will move a much longer distance in that time than a point near the poles. Because speed equals distance traveled divided by time, the speed at which objects at the poles are rotating is much lower.

Water currents at or near the ocean surfaces are usually generated by _______. These currents move _______ compared to cold, deep ocean currents. Currents deep within Earth's oceans are driven by water _______ differences. Deep ocean currents are also connected and are part of the worldwide oceanic circulation system, often referred to as the global _______, that helps regulate Earth's average surface temperature.

An observer sitting in an anchored boat in a bay is watching waves go by. She notices that there is a distance of 10 meters between wave crests, and that a new wave crest passes her boat every 5 seconds. What is the wave speed?

1

An observer sitting on the shore sees four waves with equal wavelengths travel by. The distance between the first and fourth wave crests is 30 meters. It takes 21 seconds for all four wave crests to pass. What is the wave speed?

As a fishing boat travels through the ocean, crew members watch as they pass two wave crests. The distance between the crests is 15 meters. The time it takes to travel from the first crest to the second is 7.5 seconds. What is the wave speed?

As a wave approaches the edge of the land, drag against the ocean floor causes the side closer to land to slow down while the rest of the wave continues forward. This causes a bend in the wave's overall path and this phenomenon is known as

For this day at Shell Island, in the Gulf of Mexico, the tides are predicted to reach__________ at high tide, and__________ as compared to sea level at low tide. This represents a total change in water level of__________. Tide tables are printed annually for the entire year. The reason tides can be predicted so far in advance is because of known factors affecting the ocean water, such as __________. However, the actual tides on any given day may vary from the predictions. This is due to unpredictable factors, such as __________.

Draggable item		Corresponding Item
wave height		amount of time between two wave crests (from a fixed reference point)
trough		measurement of the vertical distance between the wave's crest and trough
wavelength		horizontal distance between two wave crests, or two wave troughs
wave period		dividing the wavelength by the wave period
crest		lowermost point of a wave
wave speed		uppermost point of a wave
