    Why is Atmosphere important for Us?

    ⚛Required Answer⚛

    ✤We breathe in oxygen which is one of the components of atmosphere.

    ✤ We breathe out carbon dioxide which in turn is taken in by plants in thier respiration.

    ✤ The atmosphere prevents harmful rays of the sun from reaching us.

    ✤ The green plants take in carbon dioxide use sunlight and water to photosynthesis and we get delicious fruits vegetables and grains from them.

    ✤ These give us proteins carbohydrates sugars fats minerals and other nutrients that we need.

    ✤ The atmospheric winds transport water from the oceans deep into the continents in the form of rain.

    ✤ Atmospheric winds erode rocks and are responsible for the formation of many kinds of soils with whose fertility we grow many kinds of crops.

    ✤ Atmosphere helps in cooling monsoon rains.

    ✤ Atmosphere helps in diffusion of perfumes and helps in the travelling of sound waves.

    ✤ Thus we can say atmosphere is important for us.
