That is however rather old 'science', as the definable layers continue to the 'Exosphere' layers, or Ionosphere and Plasmasphere, which are part of the Magnetosphere, which is not spherical but toroidal (donut shaped).

Strictly the 'atmosphere' itself is the lower oxygen rich layer below the Mesosphere, but the word is also 'stretched,' due to want of another, to describe the (ever 'extending') whole structure inside the Earth Centred Inertial (ECI) Frame inside the ionized layer of the bow shock, which all orbits the sun.

Answer 2

the layers of the atmosphere are the troposphere, the stratosphere, the mesosphere, then the thermosphere. they are in order.
