When a wave breaks on the shore
Pull of a the water rushing back out to the ocean.
A wave formed far below the ocean surface, usually caused by an earthquake beneath the ocean floor.
As waves come into shore, water washes up the beach at an angle, carrying sand grains. The water and sand then run straight back down the beach. The movement of sand along the is called this....
The process of When water breaks through the sandbar and begins to flow back down the sloping ocean bottom.
Wall of rocks or concrete built along a stretch of the beach to reduce Erosion.
The daily rise and fall of Earth's waters on its coastlines.
When water reaches it's highest point

What causes tides?
The interaction of Earth, moon, and sun. (Through gravity)
A bulge of water caused by the moons gravitational pull.
High tides occur..
About every 12 hours and 25 minutes
What affects the heights of the tides during a month?
Changes in the Earth's position, the moon, and the sun.
When the sun and moon (full and new moon)are lined up and their gravitational pull produces the greatest difference between the heights of high and low tide.
One kilogram of ocean water contains how many grams of salts?
35 (35 parts per thousand)
The total amount of dissolved salts in a sample of water.
Table salt is also known as...
Sodium and chloride make up what percent of the ions dissolved in the ocean?
Ocean water is composed of what ions?
Sodium, chloride, sulfate, magnesium, calcium, potassium, and others like nitrogen and phosphorus.
The ocean's salinity is lower where?
On the ocean's surface and near the mouths of large rivers.
Why does salt water have greater buoyancy than fresh water?
Because it's density is greater because of the salt.
Is cold or warm water denser?
Cold because the molecules stay closer together.
What gases do ocean organisms use?
Carbon dioxide and oxygen
Where does oxygen in sea water come from?
The air and algae (as a product of photosynthesis)
Vertical section of the ocean where there are three temperature zones. The surface zone, the translation zone, and the deep zone.
The force exerted by the weight of the water
The arrangement of the first and third quarters of the moon, the sun and moon pull at right angles to each other.
An underwater vehicle built of materials that resist pressure. They are needed because the further you go down in the ocean the more the pressure increases.
Large stream of moving water that flows through the oceans.
Affect water to a depth of several hundred meters and are driven mainly by winds.

In the Southern Hemisphere the Coriolis effect causes currents to curve to the....
The pattern of temperature and precipitation typical of an area over a long period of time.
An abnormal climate event that occurs every two to seven years in the Pacific Ocean.
Deep currents are caused by...
Differences in the density of the ocean water
What do deep currents do?
Move and mix water around the world, carry cold water from the poles toward the equator.
The movement of cold water upward from the deep ocean. As winds blow away the warm surface water, cold water rises to replace it.
