1.Lower atmosphere: The lower atmosphere extends from the surface up to about 65 kilometers (40 miles) and contains most of the planet's mass and dust particles. It is relatively dense compared to the upper atmosphere, and its temperature and pressure decrease with altitude.

2.Middle atmosphere: The middle atmosphere lies between 65 and 110 kilometers (40 and 68 miles) above the surface. It is characterized by the presence of the Martian Mesosphere, which is a layer where temperatures decrease with altitude.

3.Thermosphere: The thermosphere is located between 110 and 300 kilometers (68 and 186 miles) above the surface. In the thermosphere, temperatures increase with altitude, and atoms and molecules are highly energized due to the absorption of solar radiation.

4.Exosphere: The exosphere is the outermost layer of Mars' atmosphere, extending from about 300 kilometers (186 miles) to the outer boundaries of the planet's influence. The exosphere is very thin, with a low density of particles, and it gradually merges with the interplanetary medium.

5.Ionosphere: The Martian Ionosphere is a region within the atmosphere where the gas becomes electrically charged due to solar radiation and interactions with the solar wind. It overlaps with the thermosphere and exosphere, and its properties are influenced by factors such as solar activity and magnetic fields.
