Key Terms
- Natural Resources
- Materials or substances that occur naturally in the environment and are used by humans, such as water, air, soil, minerals, forests, and wildlife.
- Renewable Resources
- Resources that can be replenished naturally over time, such as sunlight, wind, water, and forests.
- Non-Renewable Resources
- Resources that cannot be replenished at the same rate they are consumed, such as coal, petroleum, and natural gas.
- Deforestation
- The large-scale removal of forests for agriculture, urban development, or logging, leading to loss of biodiversity and ecological imbalance.
- Conservation
- The careful and responsible management and protection of natural resources to prevent waste and ensure their availability for future generations.
- Biodiversity

Frequently Asked Questions
What are natural resources in Class 6 Science Chapter 11?▾
Natural resources are materials found in nature that humans use for survival and development. They include air, water, soil, forests, minerals, and sunlight. They are broadly classified as renewable and non-renewable resources.
What is the difference between renewable and non-renewable resources in Class 6?▾
Renewable resources can be naturally replenished, such as solar energy, wind, water, and trees. Non-renewable resources are limited and cannot be easily replaced once used up, such as coal, oil, and natural gas.
Why is conservation of natural resources important in Class 6 Science?▾
Conservation is important because many resources are limited or take millions of years to form. Overuse causes pollution, habitat destruction, and climate change. Conserving resources ensures they are available for future generations.
What is deforestation and its effects in Class 6 Science?▾
Deforestation is the cutting down of large areas of forest. Its effects include loss of habitat for wildlife, reduced rainfall, soil erosion, increased carbon dioxide in the atmosphere, and contribution to global warming.
How can Class 6 students contribute to conservation of nature?▾
Students can contribute by saving water, using electricity wisely, reducing plastic use, planting trees, avoiding waste, and spreading awareness. Small habits at home can collectively make a big difference for the environment.
