PRESENTATION OUTLINE
Air- the invisible gasses substance surrounding the earth, mixture of mainly oxygen and nitrogen.
Composition of atmosphere -
The particles and the concentrations of the particles in the protective envelope surrounding the earth.
Troposphere-
The lowest region of the atmosphere, extending from the earths surface to a height about 3.7-6.2 miles
Stratosphere-
The layer of the earths atmosphere above the troposphere about 32 miles (50 km)
Mesosphere-
The region of the earths atmosphere above the stratosphere and below the thermosphere between 30 and 50 miles in altitude.
Thermosphere-
The region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of continuous medium.
Ionosphere -
The layer of the earths atmosphere that contains a high concentration of ions and free elements.
Exosphere-
The outermost region of a planets atmosphere.
Ultraviolet Radiation-
The part of the electromagnetic spectrum where wavelengths are shorter.
Ozone-
A colorless unstable toxic gas with a pungent odor and powerful oxidizing properties.
Green house effect -
The trapping of the Suns warmth in a planet slower atmosphere due to the greater transparency.
Global warming-
A gradual increase in the overall temperature of the earths atmosphere generally attributed to the green house effect.
