Flashcards in Resource Management Deck (78):
1

What are resources?

A supply of something that has value (e.g. water, energy, food)

2

What are the three most important resources?

Water, energy, food

3

How are resources spread over the world?

Unevenly

4

Where tends to have most resources?

HIC's

5

Where tens to have the least resources?

LIC's

6

Why is resource management difficult?

Population is growing and resources are running out

7

What is malnutrition?

Poorly balanced diet lacking in vitamins and minerals

8

What are the problems of malnourishment

Illness, people can't work so country suffers

9

What is water used for?

In the home (domestic use)
Water crops (Agriculture/ farming)
Factories (Industry)

10

Why is water unevenly distributed around the world?

Climate and rainfall

11

Many in Africa

12

What is water scarcity?

Not enough water

13

LIC's

15

In MIC's and LIC's, what is water used for most?

Agriculture (farming)

16

In HIC's. what is water used for most?

Domestic (in the home)

17

Why is energy use increasing?

The world is becoming more developed

18

What is energy used for in the home?

Lights
Cookers
TV's

19

What is the link between energy use and economic development?

As countries develop they use more energy in factories, become richer and use more energy in the home.

20

Demand for food is...

Increasing

21

Why is demand for food increasing?

Population increase

22

What are food miles?

The distance food has travelled to get to the UK

23

Why does the UK import food?

We don't have the climate for some foods (e.g. bananas) or we have a short growing season (e.g. strawberries)

24

Why do people want to buy local food?

Low food miles so less carbon added to the atmosphere transporting food.

25

What is agribusiness?

Intensive farming to maximise food production using technology and chemicals. Lyford House Farm does this.

26

What is organic produce?

Food grown without using chemicals (expensive). Riverford Organic farms do this.

27

Demand for water is...

Increasing

28

Why is the demand for water increasing in the UK?

Increasing population
More houses being built
Water based appliances (e.g. dishwashers)

29

What is a water surplus?

More water than needed

30

What is a water deficit?

Not enough water

31

Water surplus happens when...

High rainfall and low population density (North West UK- Lake DIstrict)

32

Water deficit happens when...

Low rainfall and high population density (South East UK- London)

33

Water stress is when

Demand is bigger than supply

34

How can we save water?

Water meters
Use recycled water
More efficient appliances

35

What is water transfer?

When water is moved from an area of surplus to deficit

36

Name an area where water is transferred from

Kielder Reservoir

37

Why do people think transferring water is a bad idea?

Destroy habitats
Expensive
Transporting water releases carbon dioxide

38

How is water quality managed?

Monitoring river water quality
Filter water to remove sediment
Adding chlorine to water
Strict rules on the uses of water.

39

How has groundwater been polluted?

Chemicals from factories
Chemicals from farming
Water used in power stations put back into rivers

40

What has happened to energy use in the UK?

Decreased

41

Why has energy use decreased in the UK?

Less industry/ factories
Low energy appliances
Better building insulation so less heating needed

42

What has happened to coal use in the UK?

Decreased

43

What has happened to oil use in the UK?

Decreased

44

What has happened to gas use in the UK?

Increased

45

What has happened to renewable energy use in the UK?

Increased

46

Does the UK produce all of its own energy?

No, it also imports from other countries such as Russia

47

Why has the use of coal decreased in the UK?

It produces greenhouse gasses when burned

48

What is fracking?

Pumping water deep underground to crack rocks which releases trapped gas.

49

Why is fracking controversial?

Could cause earthquakes
Can pollute underground water
Expensive

50

List two economic impacts of using nuclear energy

Very expensive to build
Provides jobs

51

List two environmental impacts of using nuclear energy

Waste is radioactive and dangerous
Waste water is warm and harms local ecosystems

52

List two economic impacts of wind farms

Expensive to build
Might reduce visitor numbers to an area
Might increase visitor numbers to an area
Lower energy bills for locals

53

List two environmental impacts of wind farms

Visual pollution
Noise pollution
Building can impact environment
Wind farms do not produce harmful gases

54

Which type of country has high energy consumption (use)

HIC's

55

Where in the world is energy consumption (use) low?

LIC's

56

What is an energy surplus?

Produce more energy than what is used

57

What is an energy deficit?

Use more energy than what is produced

58

What factors affect how much energy is produced?

Cost- some are expensive (e.g. oil rigs)

Technology- good technology means we can get to oil which we never used to be able to reach as it is deep underground

Climate- sunny and windy locations good for solar and wind energy

Physical Factors- coal, oil and gar are only found in certain areas

Political factors- some countries in Europe want Iran to stop producing nuclear power in case they use it at war/ for nuclear bombs

59

Why is global energy consumption (use) increasing?

As countries develop (get richer) they use more energy. Global population is increasing

60

What is energy insecurity?

When countries don't produce enough of their own energy so import it from other countries

61

How can a country become more energy secure?

Try to extract more of its own energy,
Make agreements with other countries in buy energy,
Use less energy/ save energy

62

Why doe people not want to extract oil from the Arctic?

Very sensitive environment, oil spill would be very damaging, very expensive to extract oil there

63

What is the link between energy and food?

Energy is used to grow crops. Crops like maize and sugar are used to produce energy.

64

What is an impact of energy security on industry?

Some countries have power cuts because they don't have enough energy. This can cause factories to shut down and cost a country a lot of money.

65

How might energy shortages cause conflict?

Russia sells gas to Europe, it could raise prices or stop supply.

66

Name one way we can increase energy supply

Use renewable energy

67

What is biomass energy?

Burning dung (animal poo) or plants

68

How does wind energy work?

Turbines on land or at sea are turned by wind to generate electricity

69

How does HEP (hydro-electric power) work?

Water flows through a dam to turn a turbine and create electricity

70

How does tidal energy work?

Dams near the sea, turbines are turned when the tide comes in and out which generates electricity

71

How does geothermal energy work?

Water is heated underground by naturally hot rocks, creates steam, steam turns turbine which creates electricity

72

How does wave energy work?

Waves force air into a chamber where it turns a turbine linked to a generator to create electricity

73

How does solar energy work?

PV cells on solar panels convert sunlight into electricity.

74

What are fossil fuels?

Coal, oil and gas formed millions of years ago.

75

Why is nuclear energy not a popular option?

It produces radioactive waste which can stay dangerous for over 100 years.

76

Where is most natural gas found?

Russia, Iran and Qatar

77

List two advantages of extracting natural gas

Cleanest of all the fossil fuels
Less risk of accidents than oil
Provides jobs
Transported lots of ways (pipes and tankers over land or sea)
Quite a lot of gas left

78

List two disadvantages of extracting natural gas

Dangerous if handled/ transported without care
Contributes to global warming
Fracking uses lots of water and can cause earthquakes
Pipelines are expensive
