Key concepts: Atmosphere and Climate (Class 9 Social Science)
The atmosphere is a layered envelope of gases that makes life possible, and its uneven heating produces weather and, over time, climate. This chapter covers atmospheric composition and structure, the factors controlling climate, the Indian monsoon and the reality of climate change.
- Atmosphere
- The envelope of gases held to the earth by gravity, which supplies oxygen and carbon dioxide, filters radiation and moderates temperature.
- Composition of the atmosphere
- Roughly 78% nitrogen and 21% oxygen with small amounts of argon, carbon dioxide, water vapour and dust.
- Troposphere
- The lowest layer, where all weather occurs, in which temperature falls with height and which contains most of the atmosphere's mass.
- Stratosphere and the ozone layer
- The layer above the troposphere, calm enough for aircraft, containing the ozone that absorbs harmful ultraviolet radiation.
