  1. Standard 6.4.1: Atmospheric Layers Atmosphere-a layer of gasses that surround the planet that makes the Earth suitable for living. It keeps us warm like a blanket. The layers of the atmosphere are classified according to changes in temperature. 5 Layers of the Atmosphere: Mnemonic devise: Early This Morning Students Trained.)

  2. exosphere-closest to space-the cold regions of outer space extend from here • thermosphere- the air is thin & very hot • mesosphere- the coldest layer-meteors are found here • stratosphere- the ozone layer is here-it’s cold except where the ozone layer is located in the upper region. Pilots prefer flying here because there’s no weather.

  3. troposphere- closest to Earth-clouds are found here-the higher up you go, the cooler it is- where all weather occurs • Atmospheric Gasses- Nitrogen & oxygen are the two most common gasses & they are found in all of the layers. • Ozone- a form of oxygen found in the stratosphere • Water vapor & carbon dioxide are important gasses for weather. They are found in the troposphere. • Differences in temperature separate the layers of the atmosphere.

  4. Why is it hard to breathe at the top of a mountain? • Air pressure- the force exerted by the gasses pushing down on an object. • Air pressure is greatest near the surface of the Earth & it decreases the further up you go. Air pressure decreases as altitude increases. • It is hard to breathe in low air pressure.

  7. Aurora Borealis, the Northern Lights, are dynamic, colorful displays of light that occur continuously along ring-shaped regions around the north and south geomagnetic poles. These rings are fueled by an electrically charged wind that blows through the solar system and is pulled close to the earth by magnetic fields around the poles. They are found in the ionisphere.
