Questions;

•        Why are the four major layers of the atmosphere separated where they are?
•        What increases the temperature in the stratosphere?
•        Can planes fly in the mesosphere? Why or why not?
•        On what does the temperature in the thermosphere depend?

Answers;

•        They are in hundrends of kilometers from the planet’s surface,to the outer space.
•       The high concentration of ozone in stratosphere.Ozone absorbs the ultraviolet radiation from the sun converts thi energy into heat,cousing air temperature to increases.
•       No,because there is no ozone layer in the mesosphere,solar radiation passé through in the layer witout affecting the weather.
•       The oxygen asorbs the ultraviolet radiation from the sun and gains significant kinetic energy.
