Air and Atmosphere | Learn with BYJU'S 

Inhale...exhale...inhale...exhale, surprising, we breathe every day, every time, but we know so little about it. What is air? Is it just around us or it is everywhere, deep in the space? Does it exist just for breathing? Have you noticed, the air feels really cold in your summer vacations in hill stations?
Watch this video to know everything about the air around us. Although, technically we call it the atmosphere - the circle of air. Learn how this atmosphere arranges itself in 4 layers above earth - troposphere, stratosphere, mesosphere, thermosphere, how the ozone layer protects us from the harmful UV rays of the sun, and why does it feel cold when we go up high in the air.
And something special for you, we also tell, why airplanes fly so high in the air.
