Chapter - 3 The Dynamic Atmosphere and Changing Climate What is Atmosphere:- The atmosphere is a layer of gases that surrounds the Earth. It is made up of gases like Nitrogen (78%), Oxygen (21%), and small amounts of Carbon dioxide, Argon, and Water vapour. It protects life on Earth and makes it possible for living organisms to survive. Why is the Atmosphere Important:- The atmosphere plays a very important role: Provides Oxygen – Needed for breathing by humans and animals. Supports Life – Plants use carbon dioxide for photosynthesis. Protects Earth – Shields us from harmful rays of the Sun. Maintains Temperature – Keeps Earth warm enough for life (greenhouse effect). Weather Formation – Clouds, rain, wind, and storms happen in the atmosphere. What is Climate:- Climate is the average weather condition of a place over a long period of time (years or decades). It includes temperature, rainfall, humidity, and wind patterns. Importance of Climate Affects Agricu...
