Relative dating atmossphere 100 questions to ask before dating

The study of Earth's atmosphere and its processes is called atmospheric science (aerology).

Early pioneers in the field include Léon Teisserenc de Bort and Richard Assmann.

However, the aurora borealis and aurora australis sometimes occur in the lower part of the exosphere, where they overlap into the thermosphere.

Aurorae shown here at the bottom of the thermosphere can actually form at any altitude in this atmospheric layer.

In general, air pressure and density decrease with altitude in the atmosphere.

Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 km (75 mi).

Several layers can be distinguished in the atmosphere, based on characteristics such as temperature and composition.

The atoms and molecules are so far apart that they can travel hundreds of kilometers without colliding with one another.

Thus, the exosphere no longer behaves like a gas, and the particles constantly escape into space.The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon.Water vapor accounts for roughly 0.25% of the atmosphere by mass.Sulfur compounds such as hydrogen sulfide and sulfur dioxide (SOEarth's atmosphere Lower 4 layers of the atmosphere in 3 dimensions as seen diagonally from above the exobase.Layers drawn to scale, objects within the layers are not to scale.The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.
