The atmosphere can be described as follows: The Earth is enveloped by a vital layer of gases known as the atmosphere, distinguishing it from other planets. This atmospheric shield plays a crucial role in safeguarding the planet by absorbing harmful ultraviolet radiation emitted by the Sun. Comprising various gases including nitrogen, oxygen, carbon dioxide, and inert gases, the atmosphere serves as a protective barrier, regulating the amount of solar radiation reaching the Earth's surface. This buffering effect facilitates the conditions necessary for life to thrive on our planet, making Earth uniquely habitable among celestial bodies in our solar system.

Weather refers to the day-to-day conditions of the atmosphere in a particular area for a short period of time with respect to the elements such as temperature, humidity, pressure, wind, rainfall, sunshine, cloud cover, etc. It changes constantly and may vary from minutes to a few months.
