What to Focus On

  • Atmosphere contains gases, water vapour and dust particles.
  • 99 per cent of atmospheric mass lies within 32 km of the earth's surface.
  • Carbon dioxide is transparent to incoming solar radiation and opaque to outgoing terrestrial radiation.

  • The atmosphere has five temperature-based layers.
  • Troposphere is the lowermost and most important layer for life and weather.
  • Tropopause separates the troposphere and stratosphere.

  • Temperature, pressure, winds, humidity, clouds and precipitation are the main elements of weather and climate.
  • These elements mainly operate in the troposphere.
  • Weather is the short-term condition of the atmosphere, while climate is the long-term pattern.
