What are the 3 parts of the hydrological cycle?

Sea, land and atmosphere

1

The hydrological cycle is a ...... system

Closed

2

What does 'close system' mean?

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

3

Hydrological cycle - 1

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

4

Hydrological cycle - 2

Water vapour - moved inland by winds

5

Hydrological cycle - 3

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

6

Hydrological cycle - 4

Water moves from one place to another
- infiltration
-percolation
-throughflow
-groundwater flow
-surface runoff
-channel flow

7

Hydrological cycle - 5 (storage of water on land)

-channel storage
-groundwater storage
-interception storage
-surface storage

8

Hydrological cycle - 6

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

9

Infiltration

Water soaks into the soil

10

Percolation

Water moves vertically down through soil and rock

11

Throughflow

Water in soil flows downhill

12

Groundwater flow

Water in rock flows downhill

13

Surface runoff

Water flows overground

14

Channel flow

Flow of water in a river

15

Channel storage

Water is held in a river

16

Groundwater storage

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

17

Interception storage

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

18

Surface storage

Water is held in things like lakes, puddles and reservoirs
