Greenhouse gases

2 Read the text and answer the questions.

The gases in the earth's atmosphere protect the earth from solar radiation and help keep the temperature on earth at the same level. Without greenhouse gases the earth would be much colder and would be covered in ice. However, this delicate balance can change if the amount of greenhouse gases in the atmosphere changes.

There are three important greenhouse gases. Firstly, water vapour (H2O) from evaporation of lakes and oceans. Secondly, carbon dioxide (CO2) from many natural processes like animal respiration, volcanic eruptions and decay or burning of organic matter. Thirdly, methane (CH4) from the production of coal, gas or oil and released by some animals like cows as part of digestion.
