Edexcel GCSE Geography revision on Climate change — evidence & causes. Aligned to the Pearson Edexcel GCSE Geography B 1GB0 specification. This bank has 10 practice questions on this topic.
Sample questions (3 of 10)
-
Question 1
Which of these is a major greenhouse gas that is released into the atmosphere by the burning of fossil fuels?
- A) Oxygen
- B) Nitrogen
- C) Carbon dioxide
- D) Argon
Show answer
Answer: Carbon dioxide
When fossil fuels are combusted for energy, carbon stored underground is released as carbon dioxide. This gas traps heat in the atmosphere, contributing significantly to the enhanced greenhouse effect.

Question 2
What is the name of the process where the Earth's average temperature rises due to the trapping of heat by atmospheric gases?
Show answer
Answer: Global warming
Global warming is the observable increase in the Earth's surface temperature. It is primarily driven by human-induced emissions that thicken the layer of greenhouse gases, preventing heat from escaping into space.

Question 3
Which natural factor can cause short-term global cooling by blocking sunlight with ash and dust?
- A) Solar flares
- B) Volcanic eruptions
- C) Orbital changes
- D) Ocean currents
Show answer
Answer: Volcanic eruptions
Volcanoes eject vast amounts of ash and sulphur dioxide into the stratosphere. These particles create a haze that reflects incoming solar radiation back into space, which can cool the planet for several years.
