Answer 1

Sea, land and atmosphere

Question 2

What does ‘close system’ mean?

Answer 2

There are no inputs or outputs, water just flows round and round

Question 3

Hydrological cycle - 1

Answer 3

Water evaporates from sea and land (transpiration - from plants)

Question 4

Hydrological cycle - 2

Answer 4

Water vapour - moved inland by winds

Question 5

Hydrological cycle - 3

Answer 5

Water vapour condenses to form clouds - alls over land as precipitation

Question 6

Hydrological cycle - 4

Answer 6

Water moves from one place to another

• infiltration
• percolation
• throughflow
• groundwater flow
• surface runoff
• channel flow

Question 7

Hydrological cycle - 5 (storage of water on land)

Answer 7

• channel storage
• groundwater storage
• interception storage
• surface storage

Question 8

Hydrological cycle - 6

Answer 8

Waters ends up in the sea - evaporates - goes round the cycle again

Question 9

Infiltration

Answer 9

Water soaks into the soil

Question 10

Percolation

Answer 10

Water moves vertically down through soil and rock

Question 11

Throughflow

Answer 11

Water in soil flows downhill

Question 12

Groundwater flow

Answer 12

Water in rock flows downhill

Question 13

Surface runoff

Answer 13

Water flows overground

Question 14

Channel flow

Answer 14

Flow of water in a river

Question 15

Channel storage

Answer 15

Water is held in a river

Question 16

Groundwater storage

Answer 16

Water is stored underground in soil and rock (an aquifer e.g chalk)

Question 17

Interception storage

Answer 17

Water lands on things like plant leaves and doesn’t hit the ground

Question 18

Surface storage

Answer 18

Water is held in things like lakes, puddles and reservoirs
