For approximately 5 percent from the Earth's surface area, throughout the north and south poles, much larger seasonal declines have been seen, and therefore are described as "ozone holes".

This layer is especially composed of very reduced densities of hydrogen, helium and several other heavier molecules which include nitrogen, oxygen and carbon dioxide closer towards the exobase. The atoms and molecules are to this point apart which they can journey hundreds of kilometres with no colliding with each other.
