Salinity
Is the force of water pressing against an object under water.
Water pressure
What percent of all the Earth's water is salt water? What percent of all the Earth's water is freshwater?

Name the three ocean zones from closest to the shore to furthest in the ocean.
1. Intertidal Zone
2. Near Shore Zone
3. Open Ocean Zone
A structure in the ocean that the ocean current cannot move.
Jetty
A continuous flow of water that flows in regular patterns.
Current
When scientists are exploring the depths of the ocean, they can only go so far before needing special equipment. What three factors limit science exploration?
Temperature, Darkness, Water Pressure
Which zone is the area between high and low tide? Because of the tide some can be underwater and some can be exposed.
Intertidal Zone
This is the very large, flat part of the ocean floor. The average depth is 15,000 feet.
Abyssal Plain
A group of microscopic organisms that are drifting in the ocean.
Plankton
How is the moon and the ocean tides related to one another?
Tides are caused by the "pull" of the sun and moon on Earth's oceans.
Open Ocean Zone
This is water that flows outward from the shore against the direction of incoming waves.
Rip Current
A submerged feature underwater that was eroded away by waves.
Guyot
What does it mean when an ocean wave breaks?
As waves approach the shoreline the bottom of the wave drags on the sea floor and slows. The top of the wave continues to move forward and "breaks."
Hydrothermal Vents are found here
Open Ocean Zone
This is the steeply sloping part of the ocean where the ocean rapidly starts to get deeper and deeper.
Continental Slope
Each continent is bordered by land. This vocabulary term is the scientific name for the underwater border of each continent.
Continental Shelf
List the five oceans in order from largest to smallest.
1. Pacific 2. Atlantic 3. Indian 4. Southern 5. Arctic
This is the zone nicknamed "The Underwater Buffet."
Near Shore Zone
A wave doesn't actually care water, but it carries something else. What is it?
