Question 6

Enhanced Greenhouse effect

Answer 6

A process where the earths surface is heated by the greenhouse effect at a higher rate due to increased greenhouse gas emissions from human activities

Question 7

Fossil fuel

Answer 7

Is a natural fuels, such as coal or gas, formed in the geological past from the remains of living organisms

Question 8

Greenhouse affect

Answer 8

A natural process where greenhouse gases trap the energy from the Sun inside the earths atmosphere, warming the Earth surface

Atmospheric hazard

Answer 17

Hazard caused by the weather and processes in the atmosphere

Question 18

Carbon capture and storage

Answer 18

The process of capturing carbon dioxide that would normally be admitted into the atmosphere, installing it underground in reservoirs

Question 19
