100

The name given to the ocean crust.

What is Deep Ocean Basin?

100

This gas is responsible for ocean acidification.

What is carbon dioxide?

100

This much pressure is added every 33 feet in ocean depth.

What is 1 atmosphere or about 15 psi.
100

A measure of the average kinetic energy in a substance.

What is temperature?

100

This type of current is controlled by the wind.

What are surface currents?

200

You visit this part of the continental margin every time you go to the beach.

What is the continental shelf?

200

Phytoplankton use this process to help take out carbon dioxide and put oxygen into the ocean.

What is Photosynthesis?

200

The name of the light zone in which there is light but no photosynthesis.

What is the disphotic or twilight zone?

200

This is an indirect measurement of how much mass is in a unit of volume.

What is density?

200

The major east coast surface current that keeps northern Europe unusually warm.

What is the Gulf Stream?

300

This is where new crust is made.

What is the mid-ocean ridge?

300

This is the acid that carbon dioxide turns into when dissolved in water.

What is carbonic acid?

300

Organisms that live in the deep ocean don't have any of these, allowing them to survive in great water pressure.

What is an air-filled sac or cavity?

300

When amount of salt needed to make 1 liter of ocean water.

What is 35 grams?

300

This controls the movement of deep ocean currents.

What is density?

400

This is not the source of energy for hydrothermal vents. It's the source of energy for everything else on Earth, though.

What is the sun?

400

Name of the compound that organisms of the ocean use to make there shells and exoskeletons with.

What is carbonate or calcium carbonate?

400

This light zone corresponds with the deep water temperature zone.

What is the aphotic or midnight zone?

400

This rises in water when salinity levels rise and/or temperature falls.

What is the density?

400

This current is a mixture of deep and surface currents that circulates throughout the world every millennium.

What is the thermohaline circulation ocean conveyor belt?

500

This process describes organisms that take in hydrogen sulfide, carbon dioxide and water and yielding water and glucose as a byproduct.

What is chemosynthesis?

500

This dissolved gas in the ocean is needed to make amino acids, which is a polymer of proteins.

What is nitrogen?

500

A SCUBA diver cannot surface too fast after a deep dive or this might leach into their brains, causing the bends.

What is nitrogen gas?

500

You lower this to increase the density of water.

What is temperature?

500

This type of ocean current stops every once in a while, resulting in wild weather patterns across the globe.

What is upwelling?
