Answers
The gaseous canopy that envelops the lithosphere and the hydrosphere is known as the atmosphere. It consists of a mixture of various gases and is believed to extend about 10,000 km above sea level. Held to the earth by gravitational attraction, the atmosphere has its maximum density at sea level and decreases rapidly upward.
Recent observations show that about 97 per cent of the atmosphere is confined within 29 km of the earth’s surface.
ADVERTISEMENTS:
Air is a mechanical mixture of gases, not a chemical compound. Of the many constituting gases, Nitrogen (N2), Oxygen (O2), Argon (Ar), and Carbon-dioxide (CO2), account for nearly 99-98% of the air by volume. Observations made by rockets show that these gases are mixed in remarkably constant proportion up to an altitude of about 80 km. In addition to these gases, other gases, water vapour and aerosols are also present in the air.
Composition of Atmosphere
The atmosphere can be divided conveniently into a number of well-marked horizontal layers, mainly on the basis of temperature. From the earth’s surface to an altitude of about 80 km the chemical composition of the atmosphere remains highly uniform throughout, in terms of the proportions of its constituent gases.
The name homosphere has been applied to this lower, uniform layer. The upper atmospheric layer varies significantly in its proportion of gases, so the name hetero-sphere has been given to that layer.
Answer:
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below
