Interpretation: The process of formation of aurora borealis and aurora Australis should be determined.
Concept Introduction:
Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.
The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition.
The different regions of atmosphere and their description are as follows:
Thermosphere:
It is the top most layers in atmosphere which has high temperature than all other layers present in atmosphere. The high temperature is due to the heat released by the reactions like continuous attack of
Mesosphere:
It is layer next to thermosphere that is the layer below the thermosphere. The increasing temperature for this layer with respect to decreasing height is due to the presence of less concentration of ozone and other gases in it.
Stratosphere:
It is found below the mesosphere layer in which the concentration of ozone and other gases are high. The increasing temperature for this layer with respect to increasing height is due to the presence of high concentration of ozone and other gases in it.
Troposphere:
The layer is below stratosphere layer and it is closest to the earth surface. It is the thinnest place which is responsible for all weather conditions since it contains almost all amounts of water vapor with it.
Aurora borealis: They are celestial lights found in northern hemisphere.
Aurora Australis: They are same as aurora borealis but found in southern hemisphere.
To explain: The process for formation of aurora borealis and aurora Australis.

- As weather balloons rise from the earths surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperatura is much lower in the upper atmosphere than at sea level. Would this temperatura effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you?arrow_forwardExplain the difference between the effects of ground- level ozone and stratospheric ozone. Why is one beneficial to human life, whereas the other is not?arrow_forwardIf you place 2.25 g of solid silicon in a 6.56-L flask that contains CH3Cl with a pressure of 585 mm Hg at 25 C, what mass of dimethyldichlorosilane, (CH3)2SiCl2, can be formed? Si(s) + 2 CH3Cl(g) (CH3)2SiCl2(g) What pressure of (CH3)2SiCl2(g) would you expect in this same flask at 95 C on completion of the reaction? (Dimethyldichlorosilane is one starting material used to make silicones, polymeric substances used as lubricants, antistick agents, and water-proofing caulk.)arrow_forward
