The greenhouse effect

Question 1

When the greenhouse effect takes place

Answer 1

During terrestrial radiation some radiation is actually trapped in the troposphere.
This means that some heat stays in the atmosphere for longer, heating up Earth. Eventually the heat is released to space

Question 2

Greenhouse gases

Answer 2

Carbon dioxide (CO2)
Methane (CH4)
Water vapour
Nitrous oxide (N2O)

Question 3

Human impact the greenhouse effect

Answer 3

Due to the increase in carbon dioxide emission (from fossil fuels), there is a high level of carbon dioxide in the atmosphere.
This means that more heat is trapped on Earth, and trapped for much longer.

Question 4

Sources of carbon dioxide emissions

Answer 4

Agriculture
Industry/Manufacture
Transportation
Residential and Commercial buildings.

Question 5

Coral reef bleaching

Answer 5

affected by both temperature increase and carbon dioxide increase in water.
Happens when corals are stressed and expel the algae in their tissues

Question 6

High altitude areas can become new habitats

Question 7
