Q

Why is the water cycle important

A
  • water vapour is vital to all climates on earth
  • water gives life to all living things
  • vast majority of water comes from ice

Q

What is the water cycle

A

The water cycle is the circulation of water around the word between the oceans, Iand and atmosphere

17
Q

What can affect the magnitude of water held in a store

A

Seasonal change
e. g. melting and freezing of ice caps

18
Q

Process of the water cycle

A
  • water is evaporated from a body of water
  • it cools and condenses into clouds
  • the clouds then precipitate as rain or snow
  • the water then makes it way back to the sea as surface run off
19
Q

what is the atmosphere

A

The gases that surrounds our planet

20
Q

what are clouds

A

a mass of condensed water vapor that floats in the atmosphere

21
Q

what is condensation

A

The process of gas cooling down into liquids

22
Q

what is evaporation

A

The process of livid heating up into gas

23
Q

What is freshwater

A

water that isn’t salty

24
Q

what is ground water

A

water that has soaked into the ground and is stored there

25
Q

what is polution

A

harmful Substances that contaminate water and the environment

26
Q

What is precipitation

A

water falling from the clouds to the ground, river and ocean

27
Q

what is water vapour

A

water in the form of gas

28
Q

What does a body of water need to be in equilibrium

A

steady input and steady output

29
Q

What can too much water cause

A

flooding downstream

30
Q

what can too little water cause

A

Drought downstream

31
Q

Name 3 Naturally occurring factors that affect water change

A

Extreme weather
wildfires
seasonal variation

32
Q

Why does extreme weather cause water change

A

Tropical storm bring large amounts of water

33
Q

Why do wildfires cause waterchange

A

The burning vegetation releases water that then condenses and the clouds move away from the area causing drought

34
Q

Why does seasonal variation cause water variation

A

more rainfall can occur in winter and less in summer

35
Q

Name 4 Human occuring factors that affect water change

A

Aagriculture
Desertification
Deforestation
urbanisation

36
Q

How does Agriculture affect water change

A

Farmers use excessive amounts of crops or not enough so local rivers are not in equilibrium

37
Q

How does desertification affect the water cycle

A

This can occur when humans have restricted the natural water cycle

38
Q

How can deforestation affect the water cycle

A

Trees hold large amounts of water so when they get cut down we loose large amounts of water storage

39
Q

How does urbanisation affect water change

A

It creates impermeable surfaces on large scale meaning no water can be absorbed into the groundwater stores
