Hydrosphere + Ocean currents (practical)

Question 1

what is hydrosphere

Answer 1

all bodies of water on earth, eg. lakes and seas

Question 2

which two main currents

Answer 2

surface/warm currents and deep/cold currents

Question 3

ocean currents effects for surrounding continents or why do we need ocean currents

Answer 3

ocean currents regulate global climate, helping counteract the uneven distribution of solar radiation reaching earths surface, ocean currents move heat and nutients around world oceans

Question 4

warm currents

Answer 4

warm currents are shallow and less salty, that makes the currents less dense so the water moves to the surface

Question 5

cold currents

Answer 5

cold currents are deep and salty, so currents are very dense and the water sinks down

Question 6

ocean conveyor belt is also known as?

Answer 6

thermohaline circulation

Question 7

the ocean conveyor belt…

Answer 7

is caused by the differencein water temperature and salinity (haline). The conveyor belt is a system in which the water moves between the cold depths amd warm surface in oceans throughout the world

Question 8

where do the currents move

Answer 8

the currents that begin near the equator (warm currents) move to the poles and vice versa

Question 9

what are the importants currents

Answer 9

equatorial current, gulf stream and antarctic circumpolar

Question 10

where does the equatorial current go

Answer 10

it goes towards north and south america from asia on the equator line

Question 11

where does the gulf stream go

Answer 11

it goes above the nordic countries from the atlantic ocean

Question 12

where does the antarctic circumpolar go

Answer 12

it goes beneath the continents towards australia

Question 13

why is the gulf stream the most significant

Answer 13

the gulf stream is the most significant current considering europe because it carries warm water northeast across western europe making northern europe warmer
