Composition of the Atmosphere The Earth is surrounded by air—a mixture of various gases that reaches up to a height of many kilometers. This envelope of air makes up our atmosphere. It is held in place by the Earth’s gravity. Almost all the atmosphere (97 percent) lies within 30 km (19 mi) of the Earth’s surface. The upper limit of the atmosphere is at a height of approximately 10‚000 km (about 6000 mi) above the Earth’s surface—a distance that is nearly as large as Earth’s diameter. The proportion

CHARLES DICKENS‚ in a note now lying before me‚ alluding to an examination I once made of the mechanism of “Barnaby Rudge‚” says — “By the way‚ are you aware that Godwin wrote his ‘Caleb Williams’ backwards? He first involved his hero in a web of difficulties‚ forming the second volume‚ and then‚ for the first‚ cast about him for some mode of accounting for what had been done.” I cannot think this the precise mode of procedure on the part of Godwin — and indeed what he himself acknowledges‚
