Practice Questions: Natural Resources | Science Olympiad for Class 5 PDF Download

Natural resources are materials or substances that exist in nature and can be used by humans for various purposes. They are essential for our daily lives and survival.

Renewable resources, such as sunlight, water, and wind, are naturally replenished, meaning they won’t run out as long as we use them wisely.

Sunlight helps plants grow and generates solar power, while water is essential for drinking, farming, and producing electricity.

These resources, like fossil fuels and minerals, take millions of years to form, and once depleted, they are gone for a very long time.

Fossil fuels are non-renewable, and if we use them carelessly, they will run out, leading to an energy crisis in the future.

Coal is used to generate electricity, and oil is used to fuel cars. Both take millions of years to form and can run out if overused.

Plants are essential for life. They give us fruits and vegetables, release oxygen during photosynthesis, and provide wood for building and making furniture.

Conservation involves saving water, reducing electricity use, planting trees, and recycling materials to protect our environment and resources for the future.

By turning off taps and using methods like rainwater harvesting, we can save water for future use and avoid wastage.

Recycling materials like paper, plastic, and metal prevents waste from piling up and conserves resources, making them last longer.

Fossil fuels like coal, oil, and natural gas provide the energy we need for cooking, transportation, and industrial activities.

We need air to survive as it contains oxygen. Additionally, wind energy from the air is harnessed to produce electricity through windmills.

Trees absorb carbon dioxide, a harmful gas, and release oxygen, which makes the air cleaner and healthier for all living beings.

Solar panels capture sunlight and convert it into electricity, providing a renewable and eco-friendly energy source.

Natural resources such as water, air, plants, and minerals are essential for our daily lives. Without them, life on Earth would not be possible.
