28 cze 2019 · The exosphere is the outermost layer of our atmosphere. “Exo” means outside and is the same prefix used to describe insects like grasshoppers that have a hard shell or “exoskeleton” on the outside of their body.
The exosphere, situated at the outermost fringes of the atmosphere, is where the transition from Earth’s gaseous envelope to the vacuum of outer space occurs. It’s also home to a sparse collection of atoms and molecules that gradually dissipate into the void beyond.
The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision-less. [1]
11 lut 2022 · The exosphere is the outermost layer of a planetary atmosphere, where the atmospheric gases are so thin that the individual gas molecules move in ballistic.
The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space. The air in the exosphere is extremely thin - in many ways, it is almost the same as the airless void of outer space.
exosphere, outermost region of a planet’s atmosphere, where molecular densities are low and the probability of collisions between molecules is very small. The base of the exosphere is called the critical level of escape because, in the absence of collisions, lighter, faster-moving atoms such as hydrogen and helium may attain velocities that ...
