Question 4

Arctic Ocean (Fact)

Answer 4

A lot of its surface is covered with ice.

Question 5

Southern (Fact)

Answer 5

It covers 4% of the Earth’s Surface.

Question 6

Salinity

Answer 6

a measure of the amount of dissolved salts in a given amount of liquid.

Question 7

Surface Zone

Answer 7

known as the sunlight zone because this is where most of the visible light exists. With the light come heat.

Question 8

Thermocline

Answer 8

a steep temperature gradient in a body of water such as a lake, marked by a layer above and below which the water is at different temperatures.

Question 9

Deep Zone

Answer 9

The deep zone is an area of very cold water that extends from the bottom of the thermocline to depths of 4000 meters or more. Within the deep zone, the temperature decreases slightly.

Question 10

Water Cycle

Answer 10

the continuous movement of water from the ocean to the atmosphere to the land and back to the ocean.

Question 11

Evaporation

Answer 11

the process by which water changes from a liquid to a gas or vapor.

Question 12

Condensation

Answer 12

water which collects as droplets on a cold surface when humid air is in contact with it.

Question 13

Precipitation

Answer 13

the action or process of precipitating a substance from a solution.

Question 14

Continental Shelf

Answer 14

the area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean. The continental shelf is geologically part of the continental crust.

Question 15

Continental Slope

Answer 15

the slope between the outer edge of the continental shelf and the deep ocean floor.

Question 16

Continental Rise

Answer 16

a sediment underwater feature found between the continental slope and the abyssal plain. This feature can be found all around the world, and it represents the final stage in the boundary between continents and the deepest part of the ocean.

Question 17

Abyssal Plain

Answer 17

Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface.

Question 18

Mid-Ocean Ridge

Answer 18

a long undersea mountain chain that forms along the floor of the major oceans.

Question 19

Rift Valley

Answer 19

a long narrow valley that forms as tectonic plates separates.

Question 20

Seamount

Answer 20

a submerged mountain on the ocean

Question 21

Ocean Trench

Answer 21

Oceanic trenches are topographic depressions of the sea floor, relatively narrow in width, but very long.

Question 22

Plankton

Answer 22

Plankton

Question 23

Nekton

Answer 23

aquatic animals that are able to swim and move independently of water currents.

Question 24

Benthos

Answer 24

the flora and fauna found on the bottom, or in the bottom sediments, of a sea, lake, or other body of water.

Question 25

Desalination

Answer 25

a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture.
