P60 Air physical properties

The thickness of the atmosphere in respect to the Earth is comparable to the thickness of the peel in respect to an peach.
Moreover, without the atmosphere, there wouldn’t be any life forms on the Earth. Air supplies oxygen that is necessary for breathing, carbon dioxide for photosynthesis and water vapour. You can’t see air, but it exists: it is unfathomable, it has a weight and volume. Air protects us from cosmic rays and solar rays.
