SPLATS about the atmosphere
The principles of the atmosphere
See also Air pressure
- Air is a substance that can be measured weighed, dissolved, condensed, frozen, and even seen when it is trapped below water or when it is liquefied.
- Air has weight, and as a result, it exerts a pressure on everything around it, operating in all directions. Air pressure is measured with a barometer.
- The Earth's atmosphere protects the planet from radiation, and also from the surface impact of most cosmic of the material that reaches the planet.
- Global systems drive the weather on the whole planet, both in the short term of a few days, and also by seasons and several multi-year patterns.
- There are a number of recognized levels in the atmosphere, and these levels include the troposphere, the stratosphere the mesosphere and the ionosphere.
- Air is made of individual gases, each of them exerting a partial pressure on everything around them. Oxygen, nitrogen and noble gases make up most of the air.
- Air is largely transparent, but it can be seen on very hot days, when you look along a hot surface, and see a heat shimmer caused by air of varying density.
- At sea, wind speed is measured on the descriptive Beaufort wind scale, and at other times, it is measured in knots, one of the few universal non-SI units.
- Chlorofluorocarbons (CFCs) are effective refrigerants, but when they escape, they cause ozone depletion in the upper atmosphere by reacting with the ozone.
