Exam points

  • identify CO2 and other greenhouse gases, including a greenhouse gas produced by dairy cattle
  • outline evidence that CO2 acts as a greenhouse gas and explain the possible temperature effect of atmospheric aerosols or volcanic ash
  • apply greenhouse-gas and aerosol evidence to explain possible changes in global temperatures in the stated environmental context

IB ESS SL 6.1.3 Greenhouse Gases and Aerosols Questions question 1

[Maximum number: 2]
Carbon capture and storage flow chart

Figure:Carbon capture and storage flow chart

the carbon-capture and storage flow chart shown above shows the process of carbon capture and storage (CCS) that can be used to manage climate change. Carbon dioxide ( CO2\mathrm{CO}_{2} ) is pumped into three different underground locations, where it is stored.

Flow 1 pumps CO2\mathrm{CO}_{2} into an underground saline reservoir.
Flow 2 pumps CO2\mathrm{CO}_{2} into an oil reservoir; CO2\mathrm{CO}_{2} replaces oil; oil is produced.
Flow 3 pumps CO2\mathrm{CO}_{2} into a coal seam; CO2\mathrm{CO}_{2} replaces methane (CH4)\left(\mathrm{CH}_{4}\right); methane is produced.

Question (a)

(a)

Outline the evidence that CO2\mathrm{CO}_{2} acts as a greenhouse gas.

Question (b)

(b)
