7

What is precipitation?

Transfer of water form the atmosphere to the ground. It can take the form of rain, snow ,hail, dew etc

8

What is interception?

Water intercepted and stored in the leaves of plants

9

What is throughflow?

Water flowing through soil towards the river channel

10

What is infiltration?

Transfer of water from the ground surface into soil where it may then percolate into underlying rocks

11

What is percolation?

Water soaking into rocks

12

What is groundwater flow?

Transfer of water very slowly though rocks

13

What is latent heat?

The energy required to change the state of water by breaking hydrogen bonds between molecules

14

What is hydrogen bonding?

A strong intermolecular force between the H+ of one water molecule and the O 2- of another , holding them together

15

What is surface tension?

How the molecules on the surface of water behave and how tightly they are held together by hydrogen bonds

16

What is atmospheric water?

Water found in the atmosphere mainly water vapour with some liquid water and ice crystals

17

What is cryospheric water?

The water locked up on the Earth's surface as ice

18

What is the hydrosphere?

A discontinuous layer of water at or near the Earth's surface waters, groundwater held in soils and rock and atmospheric water vapour

19

What is oceanic water?

The water contained in the Earth's oceans and seas but no including such inland seas as the Caspian sea

20

What is terrestrial water?

This consists of groundwater, soil moisture, lakes, wetlands and rivers

21

Which is the largest store of water?

Oceanic water

22

Where is most of the freshwater on Earth stored?

In the Antarctic and Greenland ice sheets

23

What are inputs into the drainage basin?

Precipitation
Energy from the sun

24

What are stores in the drainage basin?

Lakes
Soil/Ground water
Interception/vegetation
River flow
Surface flows

25

What are transfers in the drainage basin?

Ground water flow
Percolation
Transpiration
Precipitation

26

What are the outputs from the drainage basin?

River discharge
Evaporation
Water vapour

27

What is the fastest movement of water through the drainage basin?

Along the surface where there are relatively few obstacles in the way of the water

28

How fast is water movement though soil?

Somewhat slow, but varies more as clay soils retain water, slowing it down, but aerated soils and woodland channels allow it to move faster

29

What is the slowest form of movement in the drainage basin?

Groundwater flow, as it can be held for millennia

30

How much of the water on Earth is available for use by humans?

2.5%
