Climate Change

Question 1

Give 3 natural affects which cause climate change?

Answer 1

Orbital Change
Solar Output
Volcanic activity

Question 2

What does the Sun contain which can increase climate change?

Answer 2

Sunspots

Question 3

What does a sunspot do?

Answer 3

Occasionally creates a solar flare releasing high amounts of heated gas which travels to earth

Question 4

What can the amount of sunspots determine in terms of the climate?

Answer 4

Hotter or cooler

Question 5

What is the angle the earth is tilted at?

Answer 5

23.5 degree

Question 6

What is eccentricity?

Answer 6

Path of the earth as it orbits the sun, the orbit is not fixed and can change from circular to elliptical

Question 7

What is precession?

Answer 7

The wobble of the earth, can give areas longer days and night

Question 8

If the Earths orbital path is elliptical what does that mean for the climate?

Answer 8

At points the earth will be hotter than other parts as the earth will be closer to the sun at certain points that other

Question 9

What can volcanic ash do to the sun and what happens?

Answer 9

It will block the suns rays making the temperature on earth cool

Question 10

What does the volcanic ash turn into and what does that do?

Answer 10

Turns into acid rain droplets which reflects the suns radiation impacting the climate

Question 11

Give 3 human factors to climate change?

Answer 11

Fossil fuels
Deforestation
Agriculture (Cows)

Question 12

How do fossil fuels affect the climate?

Answer 12

Burning fossil fuels releases high amount of CO2 to the atmosphere causing global warming – accounts for 50% of greenhouse gas emissions

Question 13

How does deforestation affect the climate?

Answer 13

Removing trees from forests on a huge scale means that there are less trees which can take in CO2 for photosynthesis meaning there is less CO2 being taken in. When burned trees release the CO2

Question 14

How does agriculture affect the climate?

Answer 14

Creating food on large scales increases the amount of CO2 released via transport and farm animals such as cows. As the global demand increases the amount of CO2 released will increase

Question 15

How will climate change impact human? (3 ways)

Answer 15

Many people will have to emigrate or migrate inland due to rising sea levels
Dehydration will occur in places such as Africa and Central Europe due to lack of rain
Many ski resorts will shut due to lack of snow

Question 16

How will climate change affect the environment? (3 ways)

Answer 16

Loss of sea ice in Polar regions will mean a loss of wildlife
Coral Reefs and Mangrove swamps will be destroyed
Many grasslands etc will become deserts due to high temperatures

Question 17

What 4 things can be done to mitigate climate change?

Answer 17

Alternate energy production
Carbon Capture
Planting trees
International agreements

Question 18

Explain alternate energy supply?

Answer 18

Using renewables reduces greenhouse affect, they last longer and are cheaper.

Question 19

Explain carbon capture?

Answer 19

Taking CO2 out of emission sources and storing it underground, however is expensive and little is known of the rock CO2 is stored in

Question 20

Explain Planting trees?

Answer 20

More trees are planted to help remove CO2 due to photosynthesis. Limited biodiversity if 1 tree is planted and may be limited space

Question 21

Explain international agreements?

Answer 21

Encouragement of countries to reduce emissions of CO2

Question 22

Give 3 ways of adapting to climate change?

Answer 22

Changes in agriculture systems
Manage water supply
Reducing risk

Question 23

Explain changes in agriculture systems?

Answer 23

Dealing with changing rainfall and temperature patterns. Weather becomes much more extreme. Production may change to suit climate and a variety of crops may be used

Question 24

Explain managing water supply?

Answer 24

Ensures population can face challenges of changing rainfall, means reducing the demand and increasing supply. Areas of low supply or poor political stability will struggle

Question 25

Explain reducing risk?

Answer 25

Reduce the risk of see level rise with defences, restoring mangroves and raising houses etc
