Explanation:

An atmosphere (atmosphaera,) created in the 17th century from Greek atmos “Vapor” and sphaira “sphere” is a layer of gases that may surround a material body of sufficient mas and that is held in place by the gravity of the body.

Some planets consist mainly of various gases, but only their outer layer is their atmosphere.

Earth’s atmosphere, which contains oxygen used by most organisms for respiration and carbon dioxide used by plants, algae and cyanobacteria for photosynthesis, also protects living organisms from genetic damage by solar ultraviolet radiation. The oxygen so characteristic of our atmosphere was almost all produced by plants (cyanobacteria or, more colloquially, blue-green algae).

The present composition of the atmosphere is 79% nitrogen, 20% oxygen, and 1% other gases including carbon di oxide. The troposphere is where all weather takes place; it is the region of rising and falling packets of air. The air pressure at the top of the troposphere is only 10% of that at sea level 0.1 atmospheres.

The buffer zone between the troposphere and the next layer is called the tropopause. Just above the troposphere there is the stratosphere, where air flow is mostly horizontal. The thin ozone layer is present in the upper stratosphere zone that has a high concentration of ozone, a particularly reactive form of oxygen.

This ozone layer is primarily responsible for absorbing the ultraviolet radiation from the Sun. The formation of this layer is a delicate matter, since only when oxygen is produced in the atmosphere can an ozone layer formation. There is considerable recent concern that man-made fluorocarbon compounds may be depleting the ozone layer, with dire future consequences for life on the Earth.

The mesosphere is above the stratosphere and below the ionosphere (or thermosphere). In ionosphere many atoms are ionized, atoms either gained or lost electrons so they have a net electrical charge. The ionosphere is very thin and is also responsible for absorbing the most energetic photons from the Sun.

The structure of the ionosphere is strongly influenced by the charged particle wind from the Sun. An ore is a rock that contains a valuable or useful metal at a concentration high enough to make its mining a profitable operation.
