Let's solve the worksheet step by step and complete each sentence based on the image and general knowledge about energy sources.
---
1. A renewable resource is a natural resource that can be replaced in a...
✔ Answer: *short period of time*
Explanation: Renewable resources are those that can be replenished naturally over a relatively short time, such as solar, wind, or water.
---
2. These are examples of...
✔ Answer: *renewable energy sources*
Explanation: The diagram shows solar, biomass, hydropower, wind, and geothermal energy — all of which are renewable energy sources.
---
3. We use solar panels to get energy from the...
✔ Answer: *sun*
Explanation: Solar panels capture sunlight (solar energy) and convert it into electricity.
---
4. We use hydroelectric power stations to get energy from the...
✔ Answer: *water / flowing water / rivers*
Explanation: Hydroelectric power uses the movement of water (usually from dams or rivers) to spin turbines and generate electricity.
---
5. We use wind turbines to get energy from the...
✔ Answer: *wind*
Explanation: Wind turbines capture kinetic energy from moving air (wind) and convert it into electrical energy.
---
6. We use geothermal power plants to get energy from...
✔ Answer: *heat from inside the Earth / underground heat*
Explanation: Geothermal energy uses the natural heat stored beneath the Earth’s surface to produce electricity.
---
7. We use biomass power stations to get energy from... We can also use... to make biofuels.
✔ Answer:
- First blank: *organic matter / plants and animals / living organisms*
- Second blank: *plants / crops / organic waste*
Explanation:
- Biomass power stations burn organic material (like wood, crop waste, or animal manure) to produce energy.
- Biofuels (like ethanol or biodiesel) are made from plant materials (e.g., corn, sugarcane) or other organic substances.
