Answer 1

Its the burning of plant based organsims like plant waste like dung, an exmaple of where it is palm oil (renewable)

Question 2

What is nuclear power

Answer 2

It’s produced through clean and effecient way of boiling wager to make steam which turn a turbine to make electricity this can power homes (non renwable)

Question 3

What is fossil fuels

Answer 3

It’s a non renewable energy source that usesburied carbon organisms like dehdrated wood to create coal,oil,natural gas and more these power electricity (non- renewable)

Question 4

What is geothermal power

Answer 4

It is steam from the earth (hot water) found below the earths surface and the steam rotates a turbine that powers a generater to create electricity. (Renewable)

Question 5

What is solar power

Answer 5

This energy from the sun that is turned into electricity this may be on top of houses schools on on farms or anywhere this can power electric cars to calculators to phones to more (renewable)

Question 6

What is tidal energy

Answer 6

It’s energy from the sea thats quite deep and it uses tides and currents that move a turbine to generate power in a generator and create electricity (renewable)

Question 7

What is wind energy

Answer 7

This uses energy from the wind by the use of wind turbines to generate electricity(renewable)

Question 8

What is the three fossil fuels

Answer 8

Coal,oil,natural gas

Question 9

What in the name for things that are used faster than they can be replaced

Answer 9

Non renewable energy resources

Question 10

What is the name for where energy is stored

Answer 10

Energy stores

Question 11

Skip

Answer 11

Skip

Question 12

What is a non renewable energy source (give example)

Answer 12

Fossil fuels and nuclear fuels such as (Uranium and plutonium)

Question 13

Where does fossil fuels come from

Answer 13

Underground,such as wood over millions of years. These can be burnt to provide energy.

Question 14

What are the three fossil fuels

Answer 14

Coal,oil,(Natural)Gas

Question 15

What do fossil fuels do examples

Answer 15

. They run out eventually
. They all do damage to the enviroment
. But they provide most of our energy

Question 16

What are the 7 renewable energy sources

Answer 16

1) The sun (solar)
2) Wind
3) Water waves
4) Hydro-electricity
5) Bio-fuel
6) Tides
7) Geothermal

Question 17

What does renewable energy mean

Answer 17

. These will never run out and can replenished while used

. Most of them do damage to the enviorment but not nasty like non-renewable energy

. The trouble is they don’t provide much energy and some of them are unreliable
because they depend on weather

Question 18

What is a main way in which fuel is used (eg for work)

Answer 18

In transport

Question 19

What resource is mostly used in the uk

Answer 19

Natural gas

Question 20

What is a variable that is a controlled variable

Answer 20

Something you can change

Question 21

The pie chart show porpotions of electricity generated in the Uk from different energy sources in 2010

16 Nuclear (percent)
7 Renewable
34 Coal
43 Gas

What makes up fossil fuels?

Answer 21

77 ( 34 coal + 43 gas )

Question 22

Which of the following 3 are not a renewable energy source

Oil
Solar
Wind

Answer 22

Oil

Question 23

In some types of power stations,fossil fuels are burned to heat ( ) to produce steam

Answer 23

Water

Question 24

What is the answer

Answer 24

Carbon dioxide causes global warming

Question 25

The wind is a unreliable or reliable source

Answer 25

Unreliable

Question 26

Tides are a non renewable or renewable source

Answer 26

Question 27

If wood is to be used as a renewable energy source, what must be done each time a tree is chopped down?

Answer 27

Plant/grow(at least) one new tree

Question 28

Solar cells ( seeing from sun) are designed to transform _______________________________ energy into _______________________________ energy.

Answer 28

Light and electrical (in that order)

Question 29

The aircraft propellers are driven by electric motors.
Give one environmental advantage of using electric motors to drive the aircraft propellers rather than motors that burn a fuel.

Answer 29

No air pollution

Question 30

The world’s biggest offshore wind farm, built off the Kent coast, started generating electricity in September 2010.

One advantage of using the wind to generate electricity is that it is a renewable energy source. Give one other advantage of using the wind to generate electricity.

Answer 30

. Produces no emmisions
. Does not add to global warming
. Produces no air pollution

Question 31

Name one renewable energy source used to create electricity

Answer 31

. Solar
. Wind
. Hydroelectric
. Waves
. Geothermal
. Biofuel/biomass

Question 32

Use the graph to explain why the power output from the wind turbines was less than one sixth of the maximum.

Answer 32

Average wind speed below 6 m/s

Question 33

Having more nuclear power stations will help to avoid power cuts in the future.

Answer 33

Question 34

Nuclear fuels and the wind are two of the energy sources used to generate electricity in the UK. Explain the advantages of using energy from nuclear fuels to generate electricity rather than
(b)
using energy from the wind.
Include in your answer a brief description of the process used to generate electricity from nuclear fuels.

Answer 34

Small mass of fuel are able to generate a lot of electricty which allows for it to generate electrcity continuesly while not also being weather dependant due to it being able to run in any weather because it realise on energy from nuclear energy

Question 35

Describe how ‘carbon capture’ would prevent the build-up of carbon dioxide in the atmosphere.

Answer 35

carbon dioxide is not released (into the atmosphere) but is (caught and) stored (in huge natural containers)
meaning the enviorment is not affected
