We all know that we are surrounded by air, we feel it in the form of wind. But have you ever thought why it gets cold as we go up? Or how is it that our earth never heats up even when the sun supplies it with so much energy? Or how is the temperature at night maintained even when there is no sun? Or how is fog formed? And why is it formed mostly in winters (or in areas having low temperature)?

Today, we will look at the answers of these questions and some more as well.
