Space Atmosphere

In the ionosphere particles (hydrogen and some helium) have very large speed, many ionized to strikes (collisions) between themselves can fly a few hundred kilometers. Since the particle velocity is the physical nature of the temperature, the temperature with height gradually increases and may reach 100 – 200 g C. Mentally, you can put the Earth with its atmosphere into some pipe with an axis at a time equal to its velocity vector. In this case, clearly you can imagine how particles hit the atmosphere the particles of interstellar gas. When you hit within the projection of the Earth’s troposphere and the pipe hit and struck particle after a series of clashes remain in the atmosphere before they reach the troposphere, as can be, and to stratosphere.

If a flank attack collisions occur near the edge of the pipe within a range up to 2000 km. Particles of interstellar gas near the edge can slip through the atmosphere is not facing. In the collision atmospheric particle transfers its kinetic energy partly or wholly particles of interstellar gas, depending on the type of stroke: a central or oblique. These particles, changing direction (remember the change of direction the movement of billiard balls, and Brownian motion) with a high speed can fly beyond the tube. As a result, the Earth remains a plume of particles with more kinetic energy, carrying away the heat of the atmosphere. So carried away in the Space solar heat delivered to the Earth, and the heat from other sources.
