Seawater is primarily made up of water and salt.

What are the two compounds that make up seawater?

100

The light that penetrates the deepest in the ocean while the other colors are absorbed.

What is blue light?

100

This is one chemical property of the ocean and total amount of salt dissolved in water.

What is Salinity?

100

This is converted into organic compounds by photosynthesis.

What is Carbon Dioxide?

100

The first layer of the Ocean.

What is the Epipelagic Zone?

200

The attraction of one water molecule to another.

What is hydrogen bonding?

200

Increases dramatically with ocean depth, for every 10 meters of increased depth, another atmosphere of this is added.

What is pressure?

200

Ions such as Sodium and Magnesium come from the weathering of rocks and are carried to the sea by rivers.

What are Positive Ions?

200

These types of atoms move between the atmosphere, oceans, land, and living organisms.

What are Carbon Atoms?

200

The secondary layer of the ocean, also known as the Twilight Zone.

What is the Mesopelagic Zone?

300

The total kinetic energy of all of the particles in a substance or object.

What is heat?

300

The man is recorded to have dived to the deepest depths of the ocean.

Who is Herbert Nitsch?

300

Ions such as Chloride and Sulfide enter the ocean through hydrothermal vents and volcanoes.

What are Negative ions?

300

Average percent of the carbon dioxide emitted into the atmosphere each year into the ocean.

What is 30%

300

The only light produced in this zone, produced by animals such as angler fish.

What is bioluminescent light?

400

The only substance that naturally occurs in all three states on Earth- solid, liquid, and gas.

What is water?

400

A naturally-occurring ocean channel that allows sound to be carried between great distances.

What is SOFAR? (Sound Fixing and Ranging Channel)

400

These are present in tiny amounts in the ocean and enter the ocean through river runoff and human-derived inputs.

What are Trace Elements?

400

This affects the entire food chain, especially organisms with shells or other structures made of calcium carbonate.

What is Ocean Acidification?

400

This quaternary layer of the ocean consists of extremely cold temperatures and includes organisms such as sea pigs, baskets stars, and sea spiders. 

What is the Abyssopelagic Zone?

500

 The measure of the elastic tendency of liquids.

What is surface tension?

500

Animals such as fish, marine mammals, and species of shrimp use sound mainly for this reason. 

What is Echolocation?

500

A continuous shower of marine animal waste, decomposing phytoplankton and microorganisms, mineral dust, and debris.

What is Marine snow?

500

This causes a high mortality rate in marine larvae such as oysters and suppresses the immune system and metabolic rates of animals.

What is greater CO2 concentration?

500

This ocean zone is pitch black and includes the Mariana Trench.

What is the Hadal Zone?
