The Structure and Composition of the AtmosphereWhat is Earths atmosphere made of?

Composition of the Atmosphere (Dry Air)Atmospheric pressure at sea level= 14.7 lbs/in2= 101325 N/m2= 101325 Pa= 1013 millibars= 29.92 inches of mercury

Inches of mercury?Describe how temperature changes as you go up from Earths surface to the upper reaches of the atmosphere

Auroras occur, radio signals reflectedMeteoroids burn upMuch high f radiation is absorbedThermosphereStratosphereMesosphereTroposphereX-rays and Gamma RaysInfrared from the ground

Why does temperature in the troposphere decrease with altitude but temperature in the stratosphere increases with altitude?Explain why the thermosphere has a high temperature but does not contain much heat.Why is the sky blue? Why does it appear red at sunrise and/or sunset?

How does the troposphere get heated?What is albedo?What is weather?= the process by which energy in the atmosphere is balanced out. As long as more energy keeps coming into the atmosphere, it never gets completely balanced, so we continuously have weather.What is necessary for weather?An atmosphereA source of energy to the atmosphereAn unequal distribution of energy in the atmosphere
