تعريف exosphäre (äußerste schicht der erdatmosphäre) في ألمانية الإنجليزية القاموس.

exosphere

the uppermost layer of a planet's atmosphere

the outer-most layer of the Earth's atmosphere (500 to 1000km above surface); the only part of the atmosphere where an appreciable amount of atmospheric gases escape the Earth

The outermost zone in the Earth's atmosphere This layer has an altitude greater than 480 kilometers and is primarily composed of hydrogen and helium gas

the uppermost layer of Earths atmosphere

Outermost fringe of Earth's atmosphere

This region is considered the very outer limits of the earth's atmosphere Its lower boundary is often called the critical level of escape, where gas atoms are so widely spaced that they rarely collide with one another and have individual orbits It is estimated to be some 400 plus miles (640 kilometers) above the surface

Region of the atmosphere beyond 400 km that fades into interplanetary space

{i} highest level of the atmosphere

The outermost, or topmost, portion of the atmosphere Its lower boundary is the critical level of escape, variously estimated at 500 to 1000 kilometers above the earth's surface Also called region of escape See atmospheric shell

The exosphere is the outermost layer of the Earth's atmosphere The exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km) The lower boundary of the exosphere is called the critical level of escape, where atmospheric pressure is very low (the gas atoms are very widely spaced) and the temperature is very low

The outermost part of the Earths atmosphere It is very rarefied, and has no definite upper boundary, since it simply "thins out" into space

The layer of the atmosphere lying above 400 km altitude More Information

The uppermost layer of the atmosphere, its lower boundary is estimated at 500 km to 1000 km above the Earth's surface It is only from the exosphere that atmospheric gases can, to any appreciable extent, escape into outer space

the outermost atmospheric layer

The outermost, least dense portion of the atmosphere
