Question
Chapter 13.1, Problem 1BYL
To determine
The definition of atmosphere including its average composition.
Expert Solution & Answer
Answer to Problem 1BYL
A relatively thin layer of gas that surrounds surface of the Earth is termed as atmosphere. The dominant gases in the atmosphere are nitrogen (78.084%), oxygen (20.946%), and argon (0.934%).
Explanation of Solution
The atmosphere is the relatively thin gas layer that surrounds the surface of the Earth. It protects the Earth from the harmful high-energy radiations that are emitted from the space. It contains oxygen, water vapour, and other gases on which all forms of life depend.
The atmosphere is not completely homogeneous in the vertical, horizontal, or temporal composition. The two dominant gases present in the atmosphere are nitrogen and oxygen, and they constitute 78% and 21%, respectively. Argon is also present in a minor amount, and it is about 0.934 percent. In addition, variable amounts of water vapor are also present in the atmosphere along with carbon dioxide, methane, nitrous oxide, and ozone.
The atmosphere is characterized by the presence of different types of solids and liquids known as aerosols that includes dust, industrial pollutants, and tiny drops of liquid that are emitted from volcanic eruptions.

Discussion Question: Atmospheric Water & Weather A+
This chapter beautifully focuses on water from the small molecular scale to large-scale weather patterns. The surplus of heat at the
equator and the deficit at the Poles drives our atmospheric instability. Instability is a good thing! Without the unstable conditions, there
would not be any atmospheric motion. The overheating of the equator pumps atmospheric uplift. As the air rises into lower pressures, it
expands and cools... adiabatic cooling! The air migrates north and south and becomes denser than the surrounding air and sinks. The
sinking air enters higher pressures and creates the subtropical high pressures and adiabatic heating...whaaaa-la! We have Hadley Cells!
Not to mention, the Rainforests and World's largest deserts too!
We now can imagine the Hadley cells in three-dimensions. They more or less "sandwich" the equator during the spring and fall
equinoxes. However, what happens in the summer and winter?
