It looks like you've uploaded an educational worksheet about
fossil fuels, but the actual image content isn't visible to me. However, based on your description and the layout shown in the text, I can help you solve and explain the tasks on this worksheet.
Here’s a breakdown of the likely content and how to complete it:

🌍 Worksheet Title: Fossil Fuels
####
Task 1: Which fossil fuel is used to make these work?
You are given images of common items:
- Bus
- Lamp
- TV
- Plane
- Radiator
For each, choose
coal, oil, or gas and write it below.
✔ Solutions:
| Item | Fossil Fuel Used |
|----------|------------------|
| Bus | Oil (diesel or gasoline) |
| Lamp | Gas (natural gas for heating) or Oil (if it's an oil lamp) — typically
gas in modern homes |
| TV | Electricity from power plants → often powered by
coal or gas (depends on region) — most commonly
coal or gas |
| Plane | Oil (aviation fuel, jet fuel) |
| Radiator | Gas (natural gas) or oil (in some cases) — usually
gas |
> 🔎
Note: TVs don’t directly use fossil fuels; they use electricity generated from fossil fuels (like coal or natural gas). So the answer should reflect the source of electricity.

Task 2: Write two other uses for coal, gas, and oil.
✔ Examples:
Coal:
1. Generating electricity in power plants
2. Steel production (in blast furnaces)
Gas (Natural Gas):
1. Heating homes (for boilers and stoves)
2. Cooking (gas stoves)
Oil (Petroleum):
1. Making plastics and chemicals
2. Producing lubricants and asphalt

Task 3: How did fossil fuels begin with the energy from the sun?
✔ Explanation:
Fossil fuels began with the
energy from the sun because:
> Millions of years ago, plants and organisms absorbed sunlight through
photosynthesis, converting solar energy into chemical energy stored in their bodies. When these organisms died, they were buried under layers of sediment. Over time, heat and pressure transformed them into
coal, oil, and natural gas. The energy stored in these fossil fuels originally came from the
sun.
So, fossil fuels are essentially
stored solar energy from ancient times.

✔ Final Answer Summary:
Image Matching:
- Bus → Oil
- Lamp → Gas
- TV → Coal or Gas (electricity source)
- Plane → Oil
- Radiator → Gas
Other Uses:
-
Coal: Power generation, steel making
-
Gas: Home heating, cooking
-
Oil: Plastics, lubricants
Origin of Fossil Fuels:
They formed from ancient plants and organisms that captured solar energy via photosynthesis. After being buried and compressed over millions of years, they became fossil fuels — storing the sun’s original energy.
