Drilling deeper 🛢️
The easy oil and gas is running out. To meet demand, companies now reach for harder sources, like tar sands and shale gas. These can be extracted, but only at a greater cost to the environment. This module weighs up the debate around unconventional extraction.
Words to know 🔑
Four ideas run through this topic:
What is fracking? 🎯
What is fracking?
- Cracking underground rock to release shale gas
- Pumping oil from an easy reserve
- Burning coal in a power station
- Building solar panels
Easy or hard? ⚖️
Fuel can be reached in easier or harder ways.
Match the term 🔗
- Conventional extraction
- Unconventional extraction
- Tar sands
- Fracking
- Pumping fuel from an easy underground reserve
- Reaching harder fuel with newer, costlier methods
- Digging up oil-soaked sand and processing it
- Cracking rock with high-pressure liquid to free gas
Two sides of the debate ⚠️
Unconventional extraction is argued over. On one side are the economic gains: more energy, jobs, and less reliance on imported fuel. On the other are the environmental costs: damaged landscapes, polluted water, small earth tremors, and more greenhouse gases. Different groups weigh these up differently.
Count the costs ✅
Which THREE are ENVIRONMENTAL costs of unconventional extraction?
- Water can be polluted
- Landscapes and habitats are damaged
- Fracking can cause small earth tremors
- It creates new jobs
- It improves energy security
Who thinks what? 🔀
- An energy company
- A local resident
- An environmental group
- The government
- Wants to extract for profit and jobs
- Worries about pollution and tremors near home
- Opposes the carbon and habitat damage
- Weighs energy security against the risks

Complete the idea 🧩
As easy reserves run low, companies turn to _____ extraction. Tar sands are dug up, and shale gas is released by _____, which cracks the rock. These methods bring economic gains such as jobs and energy _____, but they also cause environmental _____ such as polluted water. Because the two sides disagree, it is a _____.
