Question

How is the atmosphere useful to us?

Answer 1

The usefulness of the atmosphere can be understood with the below mentioned points:

• The components of atmosphere have a great utility. For example, nitrogen, the most important component of the atmosphere, is needed for the growth of plants and for the fertility of soil.
• Oxygen is a life-giving gas, which is the pre-requisite for human life on the Earth.
• Carbon dioxide is needed by plants to make their own food. It also helps in maintaining the temperature of the Earth's surface by absorbing the heat radiated from the Earth surface.
• The water vapour present in the atmosphere helps in bringing rainfall on Earth.
• Ozone layer protects the Earth from harmful ultraviolet rays emitted from the Sun.
• Even the dust particles are useful to us since they act as the base during condensation to form water droplets.
