The atmosphere is not much different from the ocean that wraps around the earth's surface. It is a fluid that wraps.
The fundamental difference between the atmosphere and the oceans is the atmosphere that mixes compressed gases or expansions while the oceans contain relatively uncompressed fluids.
The ability of compression and the environment, substantially by, creates various phenomena such as wind, cloudy, rain, climate, weather, and so on. In general, the atmosphere by dividing it into two regional parts namely: low (regional) and low regional (top) regional upper atmosphere.
The lower region is the atmosphere from the earth's surface to a height of approximately 50 km. Science for this area is the science of meteorology.
While the top regional atmospheric sciences (> 50 km), known as the science of aeronomy.
