COS 'is?
The atmosphere is a mixture of gases, which are nitrogen, oxygen, carbon dioxide and other gases that are more rare, which envelops the Earth.
SIZE:
has an 'extension of about 1000 km.
FUNCTIONS:
Its function is to filter as it allows light and heat of the sun to reach Earth but prevents harmful solar radiation to life, such as UV and X ndi arrive in quantity until the earth's surface .
AREAS OF 'ATMOSPHERE:
- tropospheric : up to 10km in height, is formed by water vapor. It formed the perturbations in the troposphere. - stratospheric: up to 40km, and this is the band of nitrogen, which shields the solar UV rays.
- mesosphere and thermosphere: these occur in the polar auroras.
Higher up is the ' exosphere.
WINDS: are formed by the displacement of masses of 'high-pressure air that collide with those of low pressure.
THE DESTRUCTIVE INTERFERENCE: when the masses of low-pressure clash with those of high-pressure form violent disturbances that cyclones.
Gi Hurricanes take on the 'look' columns that rotate in air vortex motion around a central area of \u200b\u200bquiet called the "eye." Proceed at great speed and create serious damage when they come in contact with the ground.
Hurricanes are able to suck its passage enormous amounts of water to uproot trees and uncover the case.
seas can also cause tidal waves that cause abnormal flooding.
Tornadoes and trumpets 's air are too' violent and destructive they disruption, but the limited size. They are caused by 'sudden juxtaposition of two masses' air temperature and humidity vary widely.
You create a column of 'hot air that swirl around itself is drawn up. Winds affect the eight hundred miles per hour.
Tornadoes are quite common in the plains of the United States and Australia '.
aurora: between observed natural phenomena on Earth, the polar aurora is one of the most magnificent. In the polar regions light up the sky arches of green and white that stretch from side to side ' other 's horizon.
turn the polar aurora are powerful explosions occurring on the Sun
