What is Atmosphere: A Protective Layer of Gases Enveloping a Planet


An atmosphere is a layer of gases surrounding a celestial body, such as a planet or moon, which helps to protect the planet’s surface from various hazardous events, such as meteor impacts and radiation from the sun. Earth’s atmosphere is composed of 78% nitrogen, 21% oxygen, and other gases in smaller amounts. The atmosphere also plays a crucial role in regulating the temperature, weather, and air pressure of the planet.

Composition of an Atmosphere:

  • Composition of the atmosphere can vary greatly from planet to planet, but it typically consists of a mixture of gases, such as nitrogen, oxygen, carbon dioxide, and methane.
  • The composition of the atmosphere affects the planet’s climate, temperature, and the ability to support life.

Functions of an Atmosphere:

  • Protects the surface of the planet from harmful radiation and meteor impacts.
  • Regulates the planet’s temperature and weather by trapping heat and allowing it to circulate.
  • Supports life by providing the necessary elements for respiration, such as oxygen.
  • Provides a medium for the movement of sound and weather patterns, such as winds and storms.
