what is Exosphere please tell the answer
Answers
Answer:
The exosphere is the outermost layer of our atmosphere. ... The exosphere is really, really big. That means that to get to outer space, you have to be really far from Earth. The exosphere has gases like hydrogen and helium, but they are very spread out.
Answer:
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 too low for them to behave as a gas by colliding with each other
The exosphere is the outermost layer of the atmosphere (that is, it is the upper limit of the atmosphere) and extends from the exobase, which is located at the top of the thermosphere. The exosphere begins variously from approximately 2,300,000 ft to 3,280,000 ft above the surface, where it interacts with the magnetosphere, to space. Each of the layers has a different lapse rate, defining the rate of change in temperature with height. Initial atmospheric composition is generally related to the chemistry and temperature of the local solar nebula during planetary formation and the subsequent escape of interior gases.
The exosphere 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.
