Science

• The blanket or envelope of gases surrounding the earth is called the atmosphere.
• Gases in the atmosphere Nitrogen -78%

  Oxygen - 21%

  Trace gases - 1%
• Troposphere makes up approximately 75% of the total mass of the atmosphere and contains 99% of the atmospheres water
• Troposphere where wind clouds and water vapor are found
• Components of trace gases carbone dioxide inert gases Hydrogen methane ozone
• Troposphere makes up approximately 75 % of the total mass of the atmosphere and contains 99 percent of atmospheres water
• Wind clouds and water vapor are found in this layer Troposphere
• The air in this layer is constantly moving this is the reason why airplanes experiences a bumpy ride which is known as turbulence
• The temperature in this region decreases as the altitude increases Troposphere
• Stratosphere the temperature in this layer increase with altitude
• Ozone layer it protects us from the harmful ultraviolet rays coming from the sun
• Mesosphere The temperature in this layer decreases with altitude
• Mesosphere the coldest layer of the atmosphere surrounding Earth
• Thermosphere  Comparatively closer to the sun and iy absorbs a large amount of solar reaction.
• The temperature in this layer increases tremendously as the distance from the earth becomes greater. Thermosphere
• Orbiting the Thermosphere is the International Space Station
• Ionosphre ion region
• Aurora borealis and aurora australis is found in the Thermosphere
• Exosphere the temperature int his region varies from very hot to very cold
• Artificial Sattalite orbit in this layer Exosphere
• Aurora borealis in the north

  Aurora australis in the south
