What Class 6 Science Chapter 11 Covers
11.1–11.4 Air, Water, Solar Energy & Forests examines the composition of air (78% nitrogen, 21% oxygen, 1% argon/carbon dioxide/other gases) and wind energy/firki (11.1), freshwater scarcity, water pollution and rainwater harvesting including stepwells (bawadi) (11.2), direct and indirect uses of solar energy (11.3), and forest conservation including the Chipko movement and Van Mahotsav (11.4).
11.5–11.8 Soil, Rocks, Minerals, Fossil Fuels & Conservation investigates how soil forms by weathering of rocks and humus (11.5), how coal, petroleum and natural gas (LPG/CNG) form over millions of years as fossil fuels (11.6), and distinguishes renewable resources (air, water, sunlight, forests) from non-renewable resources (coal, petroleum, natural gas, minerals, rocks) (11.7–11.8).

FAQ
What is the percentage composition of air?
Air is a mixture of gases containing approximately 78% nitrogen, 21% oxygen, and about 1% argon, carbon dioxide, water vapour and other gases.
What is the difference between renewable and non-renewable natural resources?
Renewable resources (like sunlight, air, water and forests) get replenished by nature within a reasonable period, whereas non-renewable resources (like coal, petroleum, natural gas and minerals) exist in limited quantities and take millions of years to form.
