 Class 9 – Chapter 3: Atmosphere and Climate https://link.amazon/B01vdn9oG 1. Atmosphere:-  The atmosphere is the blanket of air surrounding the Earth. Held by Earth's gravity. Essential for life because it: Provides oxygen. Protects Earth from harmful UV rays. Maintains Earth's temperature. Controls weather and climate. 2. Composition of Atmosphere:-  Gas Percentage Nitrogen 78% Oxygen 21% Argon 0.93% Carbon dioxide 0.04% Other gases 0.03% Other Components Water vapour (0.1–0.4%) Dust particles Importance Nitrogen helps plant growth. Oxygen supports life. Carbon dioxide is used in photosynthesis. Water vapour forms clouds and rainfall. Altitude:-   The height of a locationabove mean sea level is called altitude. Usually mesured in meteres or feet. The mean sea level is considered zero. 3. Layers of the Atmosphere (i) Troposphere Height: 0–12 km Weather changes occur here. Contains air, clouds and water vapour. Temperature decreases with height. Trop...
