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

The warm top layer of the ocean water. It can extend to 300 M below sea. sunlight heats the top 100m to the surface zone. surface currents mix the heated water with cooler water below.

Question 8

thermocline

Answer 8

the second layer of ocean. it can extend from 300m below sea level to about 700m below sea level. in the thermocline, temperature drops with increased depth faster than is dose in the other two zones.

Question 9

deep zone

Answer 9

the bottom layer that extends from the base of the thermocline to the bottom of the ocean, the temperature in this zone can range from 1 degree c to 3 degrees c

Question 10

water cycle

Answer 10

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

Question 11

evaporation

Answer 11

the sun heats liquid water, causing it to rise into the atmosphere as the water vapor. this physical change from a liquid to a gas is called evaporation. water evaporation directly from oceans, lakes, rivers, falling rain, plants, animals, and other sources.

Question 12

condensation

Answer 12

as water vapor rises into the atmosphere. it cools and interacts with dust particles. eventually, the water vapor turns to liquids water. this change form a gas liquid is called condensation.

Question 13

precipitation

Answer 13

when water droplets become heavy enough, they fall back to earths surface as precipitation. precipitation is solid or liquid water that falls to earth. most precipitation falls directly back into the ocean.

Question 14

continental shelf

Answer 14

the gently sloping section of the continental margin located between the shoreline the continental slope

Question 15

continental slope

Answer 15

the steeply inclined section of the continental margin located between the continental rise and the continental shelf

Question 16

continental rise

Answer 16

the gently sloping section of the continental margin located between the continental slope and the abyssal plain

Question 17

abyssal plain

Answer 17

a large flat, almost level area of the deep-ocean basin

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 separate

Question 20

seamount

Answer 20

a submerged mountain on the ocean floor that is at least 1,000 m high and that has volcanic origin

Question 21

ocean teach

Answer 21

a steep, long depletion in the deep-sea floor that runs parallel to chain of volcanic islands or a continental margin

Question 22

plankton

Answer 22

the mass of mostly microscopic organisms that float or drift freely in freshwater and marine environments

Question 23

nekton

Answer 23

all organisms that swim actively in open water independent or currents

Question 24

benthos

Answer 24

the organisms that live at the bottom of the sea or the ocean

Question 25
