18:58 Composition of the atmosphere. The five most abundant gases in the atmosphere (listed here in alphabetical order): argon (Ar), carbon dioxide (CO 2 ), nitrogen (N 2 ), oxygen (O 2 ), and water vapor (H 2 O) (you should know approximate concentrations of most of these).
18:58 The liquid nitrogen is -320° F, and is 75% of the air we breathe. 20% of the air we breathe is oxygen 5 most abundant gases in the atmosphere Nitrogen (N2) – 77% Oxygen (O2) – 20% Water Vapor (H2O) – 2% argon (Ar) – 1% Carbon dioxide (CO2) - .038% Greenhouse gases: water vapor (H 2 O), carbon dioxide (CO 2 ) and others. What do they do? Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earth’s surface roughly constant. International agreement has led to a decrease in the usage of one of the greenhouse
