[The outermost] region of the [Earth's] atmosphere above about 500 km from which the lighter gases may escape to space. 5, record 1, English, - exosphere
Record number: 1, Textual support number: 1 CONT
The exosphere is the uppermost layer of the atmosphere. On Earth, its lower boundary is estimated at 500 km to 1000 km above the Earth's surface, and its upper boundary at about 10,000 km. It is only from the exosphere that atmospheric gases can, to any appreciable extent, escape into outer space. 6, record 1, English, - exosphere
Record number: 1, Textual support number: 2 CONT
The exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km). The lower boundary of the [Earth's] 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. 7, record 1, English, - exosphere
Record number: 1, Textual support number: 3 CONT
Thermosphere and exosphere are the parts of the upper atmosphere of the Earth where artificial satellites and spacecrafts are revolving. 8, record 1, English, - exosphere

L'exosphère est la dernière couche d'atmosphère terrestre qui se situe au-dessus de la thermosphère. Cette couche se définie comme la région de l'atmosphère où les collisions entre particules sont rares, considérées comme négligeables. Les atomes s'y comportent librement, certains s'échappent même dans l'espace. La base de l'exosphère (l'exobase) se situe entre 350 et 800 km d'altitude suivant la température à la thermopause, qui est liée à l'activité solaire. L'hélium et l'hydrogène y sont les éléments prépondérants. Elle s'étend jusqu'à la limite extrême de l'atmosphère, soit 50 000 kilomètres. On ne trouve plus là que quelques atomes d'hydrogène. C'est dans cette couche, que la plupart des satellites sont placés en orbite. 3, record 1, French, - exosph%C3%A8re
