<li>The <b>Troposphere</b> is the atmospheric layer closest to the surface of the earth.It contains the largest percentage of the total mass of the atmosphere.</li>
<li>The <b>stratosphere</b> is the second major layer of air in the atmosphere.<b>Ozone is formed in stratosphere</b>.</li>
<li><b>This layer of calm and clear air is preferred for high speed jet flights because of the absence of air pockets.</b></li>
<li>Above stratosphere is <b>Mesosphere</b>, it extends from 50 to 80 km.</li>
<li>Above mesosphere lies <b>the Ionosphere, which has electrically conducting layers that help in radio communication.</b></li>
<li>The <b>Thermosphere</b> is located above the mesosphere .</li>
<li>The atmospheric pressure is measured by an instrument called a <b>Barometer.</b></li>
<li>SI unit of pressure is <b>Pascal.</b> since pascal is a very small unit of pressure, we normally express pressure in <b>kilopascal (kPa)</b></li>
