What Is in Nature’s Treasures? (Class 6 Science Chapter 11)
- Everything we get from nature and use is a natural resource — air, water, energy from the Sun, forests, soil, rocks, minerals and fossil fuels. Things people make out of them (bulbs, furniture, solar panels, bicycles) are human-made resources.
- Air is a mixture of gases: about 78% nitrogen, 21% oxygen and 1% argon, carbon dioxide and other gases. Moving air is wind, and wind farms such as Muppandal (Tamil Nadu), Jaisalmer (Rajasthan) and Brahmanvel (Maharashtra) turn it into electricity.
- Water covers about two-thirds of the Earth, but most of it is salty ocean water. Only a tiny part of the freshwater in ponds, rivers, lakes and wells is easy to reach — so water must be used with care, and rainwater harvesting (bawadi in Rajasthan, vav in Gujarat) is an age-old Indian answer to scarcity.
- The Sun is the main source of energy on Earth. Plants use sunlight to make food, animals eat plants, and we eat both — so every meal is really sunlight in another form.
- Soil forms when rocks disintegrate under the action of the Sun, water and living organisms over thousands of years. Rocks are made of minerals, from which metals such as iron, aluminium, copper and gold are obtained.
- Renewable resources (air, water, forests, sunlight, wind) are restored by nature within a reasonable time. Non-renewable resources (coal, petroleum, natural gas, minerals, rocks, soil) are limited and get exhausted once used — “Earth provides enough to satisfy every man’s need but not for every man’s greed.”
