GCE Geography 2024 Theory — Question 8

Model answer

(a) Atmospheric resources are elements and conditions in the earth's atmosphere that can be utilized for various human activities and natural processes. These resources include oxygen, carbon dioxide, water vapour, solar radiation and wind. (b) Three importance of atmospheric resources: i. Supports life: Atmospheric resources provide essential elements like oxygen, water and temperature regulation to sustain life on earth. ii. Agriculture and food production: Atmospheric resources like carbon dioxide, nitrogen and weather patterns are crucial for plant growth and crop production. iii. Energy and transportation: Atmospheric resources like wind and air currents enable renewable energy generation (e.g. wind power) and facilitate air transportation. (c) Three human activities that adversely affect the composition of the atmosphere: i. Burning of fossil fuels: This releases carbon dioxide, sulphur dioxide and other pollutants that alter the atmosphere's natural composition. ii. Deforestation: This reduces the number of trees available to absorb carbon dioxide, increasing greenhouse gas concentration. iii. Industrial processes: Manufacturing and industrial activities release various pollutants, including particulate matter and toxic gases, into the atmosphere. (Also acceptable: agricultural activities producing methane, transportation emissions, fossil fuel extraction and refining, waste management/burning.)
