Fossil Fuels: Formation and Environmental Impact

Fossil Fuels: Formation and Environmental Impact

Year 7 Science Understanding Earth's Precious Resources Lesson 3 of 18

WALT (We Are Learning To)

Explain what fossil fuels are and describe their formation Understand how coal and oil are formed over millions of years Evaluate the environmental impact of using fossil fuels

What Are Fossil Fuels?

Ancient energy resources formed from the remains of living things Took millions of years to form Main types: Coal, Oil, and Natural Gas Non-renewable energy sources

Coal Formation Process

Oil Formation Process

Create Your Fossil Fuel Formation Diagram

Work in groups of 4-5 students Choose either coal OR oil formation Create a large labeled diagram showing the process Include: organic matter → burial → heat/pressure → fossil fuel Use poster paper and colored markers Be ready to explain your diagram to the class

Environmental Impact of Fossil Fuels

{"left":"Air pollution from burning coal and oil\nGreenhouse gas emissions causing climate change\nHabitat destruction from mining and drilling\nWater pollution from oil spills and mining runoff","right":"Provides energy for electricity and transportation\nCreates jobs in mining and energy industries\nRelatively cheap and reliable energy source\nPowers most of our modern technology and lifestyle"}

Reflection and Summary

Why is it important to understand how fossil fuels form and their impacts? Key Points: • Fossil fuels took millions of years to form • They provide energy but cause environmental problems • Understanding formation helps us appreciate Earth's processes • We need to consider alternatives for the future
