Some jet aircraft fly in the next layer, the stratosphere, which contains the jet streams and a region called the ozone layer. The next layer, the mesosphere, is the coldest because the there are almost no air molecules there to absorb heat energy.

This layer is mainly composed of extremely low densities of hydrogen, helium and several heavier molecules including nitrogen, oxygen and carbon dioxide closer to the exobase. The atoms and molecules are so far apart that they can travel hundreds of kilometres without colliding with one another.
21 Ιαν 2023 · The gases ozone, water vapor, and carbon dioxide are only minor components of the atmosphere, but they exert a huge effect on the Earth by absorbing radiation in the ranges indicated by the shading. Ozone in the upper atmosphere filters out the ultraviolet light below about 360 nm that is destructive of life.
Because there are few gas molecules in the mesosphere to absorb the Sun’s radiation, the heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90 degrees C (-130 degrees F).
24 Μαΐ 2024 · Carbon dioxide (CO 2) makes up only 0.036% of the atmosphere by volume. Carbon dioxide is essential to photosynthetic processes of plants. Huge quantities of carbon are stored in plant tissue, deposits of coal, peat, oil, and gas.
6 Νοε 2020 · Trace gases include carbon dioxide, ozone, and specific gases such as argon, neon, helium, krypton, and xenon, which are very inert and essentially involved in any chemical transformation within the atmosphere . The atmosphere also contains sulphur, fluorocarbons, and dust and ice particles.
Carbon dioxide is a heat-trapping greenhouse gas. Carbon Monoxide: Carbon monoxide in the air comes from burning fuel in vehicles, volcanoes, and forest fires. It is a poisonous gas. Methane: Methane gas is released into the air from landfills, livestock and their manure, and from oil and gas wells. It is also created when organic material ...
