Answer 2

Greenhouse effect

Question 3

Answer 3

Greenhouse effect stronger.This is called the enhanced greenhouse effect.Too much greenhouse gas in the atmosphere means too much energy is trapped and the planet warms up

Question 4

How does farming contribute to global warming

Answer 4

Farming of cattle produces a lot of methane.
Rice paddies contribute to global farming because flooded fields emit methane.
Trees absorb CO2 .When land is cleared of trees for agriculture it stops the absorption of CO2 which leaves more CO2 in the atmoshphere

Question 5

How does energy contribute to global warming

Answer 5

CO2 is released into the atmosphere when fossil fuels like coal, oil and gas are burnt.

Question 6

How does transport contribute to global warming

Answer 6

Most cara, lorries and plnes run on fossil fuels which release greenhouse gases when burnt.
Car ownership is rapidly increasing in countries which are developing.This mwans there are more cars on the road.This increases congestionn.As a result car engines are running for longer so the amount of greenhouse gases released increases
