Fascinating Fact:
Understanding the greenhouse effect helps geographers and scientists explain why reducing emissions is vital for limiting future climate change.
In GCSE Geography, the greenhouse effect is studied as a key driver of climate change. You learn how energy from the Sun, greenhouse gases, and human activities interact to warm the atmosphere. The topic links to global temperature patterns, extreme weather, and international efforts to reduce emissions through targets, agreements, and changes in energy use.
Key Terms
- Greenhouse effect: The natural process where certain gases trap heat in the atmosphere and keep the Earth warm enough for life.
- Greenhouse gas: A gas, such as carbon dioxide or methane, that absorbs and re-emits heat energy in the atmosphere.
- Enhanced greenhouse effect: Extra warming of the Earth caused by human activities that increase greenhouse gas concentrations.
Frequently Asked Questions (Click to see answers)
What is the greenhouse effect in GCSE Geography?
In GCSE Geography, the greenhouse effect is explained as the way greenhouse gases trap some outgoing heat, keeping Earth warm. Without it, the planet would be too cold for most life.
Which gases cause the enhanced greenhouse effect?
The main gases linked to the enhanced greenhouse effect are carbon dioxide from burning fossil fuels, methane from farming and waste, and nitrous oxide from fertilisers and industry.
How does the greenhouse effect link to climate change?
When greenhouse gas levels rise, more heat is trapped in the atmosphere. This raises average global temperatures, which contributes to climate change, melting ice, and changing rainfall patterns.
