Section C: Short Answer Questions (6 marks)

• What are non-renewable resources?
  Non-renewable resources are those that take millions of years to form and cannot be replaced quickly once used.
  Examples: Coal, Petroleum
• Two ways to conserve electricity:
• Use energy-efficient appliances.
• Switch off lights and fans when not in use.
• Why are alternative sources of energy important?
  They are naturally replenished, reduce pollution, and are cost-effective since the main source (sun, wind, etc.) is free.

 

Section D: Application-Based Questions (9 marks)

Rainwater harvesting helps conserve resources by collecting and storing rainwater for household use, reducing dependence on groundwater and preventing water wastage.

Three ways to conserve resources in school:

• Use LED lights.
• Turn off fans and projectors when not needed.
• Encourage students to bring water in bottles to avoid wastage

Difference Between Renewable and Non-renewable Resources:

Type of Resource	Definition	Example	Nature
Renewable	Resources that are naturally replenished continuously	Sunlight	Inexhaustible
Non-renewable	Resources that take a long time to form and cannot be replaced quickly	Coal	Exhaustible
