      <description>&lt;p&gt;image of the earth showing how much water and air their is in relationship to the size of the planet &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Highlights and Sticky Notes:&lt;/strong&gt;&lt;p&gt;&lt;div class=&quot;content&quot;&gt;&lt;img title=&quot;&quot; src=&quot;http://data.tumblr.com/GXcjc7XP05wa42v41GMFReAT_500.png&quot; alt=&quot;Left: All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc. Right: All the air in the atmosphere (5140 trillion tonnes of it) gathered into a ball at sea-level density. Shown on the same scale as the Earth.

Update: this image has received a lot of attention and several people have emailed me asking whether I created it. Both the text and image were found on an internet message board, so I&amp;#8217;m not sure who made it or whether it&amp;#8217;s accurate.

Andrew Nowicki writes:


  The mass of the oceans is approximately 1.35 × 10^18 tonnes, or about
  1/4400 of the total mass of the Earth (ranges reported: 1.347 × 10^21 to
  1.4 × 10^21&amp;#160;kg.) source
  
  The average mass of the atmosphere is about 5 quadrillion metric tons or
  1/1,200,000 the mass of Earth. According to the National Center for
  Atmospheric Research, &amp;#8220;The total mean mass of the atmosphere is 5.1480 ×
  10^18&amp;#160;kg with an annual range due to water vapor of 1.2 or 1.5 × 10^15
  kg depending on whether surface pressure or water vapor data are used;
  somewhat smaller than the previous estimate. The mean mass of water
  vapor is estimated as 1.27 × 10^16&amp;#160;kg and the dry air mass as 5.13 × 10^18&amp;#160;kg.&amp;#8221; source


Andrew&amp;#8217;s numbers are a good starting point, but I&amp;#8217;m not sure they refute the image&amp;#8217;s depiction or its caption. I&amp;#8217;m currently traveling so I can&amp;#8217;t do the math right now, but I will make an attempt to verify this once I have a chance. If anyone else wants to take a shot, I&amp;#8217;d be happy to post your results.&quot; /&gt;&lt;/div&gt;&lt;/p&gt;&lt;p&gt;&lt;p&gt;&lt;strong&gt;Tags:&lt;/strong&gt; &lt;a href='http://www.diigo.com/user/theenergynet/eco.news' rel='tag'&gt;eco.news&lt;/a&gt; &lt;a href='http://www.diigo.com/user/theenergynet/ecology' rel='tag'&gt;ecology&lt;/a&gt; &lt;a href='http://www.diigo.com/user/theenergynet/images' rel='tag'&gt;images&lt;/a&gt; &lt;a href='http://www.diigo.com/user/theenergynet/water' rel='tag'&gt;water&lt;/a&gt; &lt;a href='http://www.diigo.com/user/theenergynet/zounds%21' rel='tag'&gt;zounds!&lt;/a&gt; &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Posted by:&lt;/strong&gt; &lt;a href='http://www.diigo.com/user/theenergynet'&gt;theenergynet&lt;/a&gt;&lt;/p&gt;</description>
