Q

Why will planting more trees help us stop or slow down climate change

A

Trees absorb carbon dioxide and give out oxygen. This will control the amount of carbon in the atmosphere and help battle against fossil fuels.

Q

what problems are climate change making for Greenland

A

climate change is causing an increase in tempretures meaning that more ice is melting, leading to an increase in sea levels and a decrease in land as the water is steadily washing it away.

Q

give the definition of droughts

A

As tempretures increase, soils dry up: this makes droughts worse

Q

give the definition of extinction

A

Animals and plants are adapted to specific conditions. Climate change means those conditions are changing, making life harder and harder.

Q

give the definition of the rise of sea levels

A

Melting ice on land rises sea levels. The sea also expands as it gets warmer, increasing levels even more

Q

give the definition of wildfires

A

Wildfires happen during periods of hot, dry weather. Climate change makes these hot, dry weather conditions more likely to occur

Q

give the definition of heatwaves

A

As global tempretures rise, heatwaves get hotter and happen more often. In the UK, heatwaves are now 30 times more likely to happen because of climate change

Q

give the definition of storms

A

Higher tempretures mean that more water evaporates from the surface of the oceans. More moisture in the atmosphere means more rain. The storms also have more energy.

Q

how can adding grass to roofs help us tackle climate change

A

add grass to roofs, this will allow it to stay cooler in the summer and warmer in the winter as well as the roofs soak up carbon emissions

Q

how can building more wind turbines help us tackle climate change

A

the electricity generated by wind turbines has a zero carbon emission although it is unpredictable as it is based of weather

Q

how can less cars more bikes help us tackle climate

A

cycling produces no carbon emissions - plus it cuts congestion and air pollution

17
Q

how does planting more trees help us to tackle climate change

A

trees cut carbon emissions because trees soak up carbon dioxide - especially younger trees

18
Q

how would the world be diffrent without green house gases

A

the world would become much colder so much of the planet would become unhabitble, as plants and trees would be unable to grow

19
Q

what is step 1 of the greenhouse effect

A
  1. shortwave radiation from the sun travels towards earth
20
Q

what is step two of the green house effect

A
  1. about half is reflected or absorbed by clouds and the atmosphere
21
Q

what is step three of the green house effect

A
  1. the rest reaches earth where it is absorbed by land and oceans
22
Q

what is step four of the green house effect

A
  1. earth releases the heat as longwave radiation back towards space
23
Q

what is step 5 of the greenhouse effect

A

some of this heat passes directly through the atmosphere

24
Q

what is step 6 of the greenhouse effect

A

some of the radiation is trapped by greenhouse gases keeping earth warmer

25
Q

what is the definition of enhanced greenhouse gases

A

is the increase of the greenhouse effect because of human activities have added to a natural effect

26
Q

how much carbon is locked away in the earths core and mantel

A

90 percent

27
Q

carbon cycles are…

A

all balanced apart from one which is human activities
