This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils learn about greenhouse gas emissions from transport and industry, and the use of renewable energy resources and changes to transport infrastructure that could reduce emissions.
Lesson Summary
You will learn to identify the biggest producers of carbon dioxide and suggest changes to reduce their emissions.
Key Notes
- Carbon capture and storage separates CO₂ from other emissions and stores it in suitable deep underground locations
- Carbon capture and storage can reduce CO₂ emissions but is very expensive
- The energy sector uses fuel for heating, electricity generation and transport as well as manufacturing and construction
- The energy sector produces approximately 75% of global greenhouse gas emissions
- Greenhouse gas emissions can be reduced by using less energy and switching to renewable energy sources
Vocabulary To Learn
- greenhouse gases: gases in the atmosphere that keep it warmer than it would be without them
- carbon capture and storage: the separation of carbon dioxide from other emissions and the storage of it in deep underground locations
- renewable resources: an energy resource that can be replenished as quickly as it is used so will not run out
- energy industry: all the industries involved in generating electricity or providing fuels
Common Mistakes To Avoid
- It is pointless to take action on climate change if some other countries are not.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Carbon capture and storage separates CO₂ from other emissions and stores it in suitable deep underground locations. Carbon capture and storage can reduce CO₂ emissions but is very expensive.
2. Define this scientific word and use it in context. 'greenhouse gases'
gases in the atmosphere that keep it warmer than it would be without them. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: It is pointless to take action on climate change if some other countries are not. Correction: Discuss how international agreements can enable many countries take action together. And that developing green technologies ahead of other countries may help UK industry in the future.
