5 days ago · Earth’s atmosphere is bounded at the bottom by water and land—that is, by the surface of Earth. Heating of this surface is accomplished by three physical processes— radiation , conduction , and convection —and the temperature at the interface of the atmosphere and surface is a result of this heating.

The Earth's atmosphere is composed of layers of gas that protect the planet. Rei Ueyama, an atmospheric scientist at NASA Ames Research Center, discusses its functions and importance.
3 days ago · The composition of Earth's atmosphere is determined by the by-products of the life that it sustains. Dry air (mixture of gases) from Earth's atmosphere contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and traces of hydrogen, helium, and other "noble" gases (by volume), but generally a variable amount of water vapor is ...
1 day ago · It involves the movement of thermal energy from one place to another and occurs in three fundamental ways: conduction, convection, and radiation. By examining these mechanisms, we can gain a deeper understanding of atmospheric processes and their effects on our environment. 1. Conduction. Conduction is the process of heat transfer through a ...
