In the center, Lake Michigan and Chicago are clearly visible. The absence of clouds over the lakes is because of different temperatures between the landmass and the lakes. The warming land surface causes air to rise and form clouds, while the cold lake water retards cloud growth and remains cloud free."</div> <bR> <bR> <bR> <div> <B></B></div> <bR> <bR> <div> The Great Lakes are the largest combined body of fresh water in the world, covering an area of 95,000 square miles (246,050 square kilometers).  Lake Michigan alone covers an area of 22,300 square miles (57,755 square kilometers).  The Great Lakes were formed about 12,000 years ago at the end of the ice age, when glacier-carved lake basins were filled with meltwater.  The lakes are interconnected by straits, short rivers, and canals.  Water from the Great Lakes exits at the eastern end of Lake Ontario into the St. Lawrence River, which flows eastward into the Atlantic Ocean."</div> <bR> <bR> <div> <I><B>Public domain photos courtesy of NASA: </B></I>"<FONT SIZE="1" COLOR="#000000" FACE="Arial" >This material is not subject to copyright protection.  It was obtained from U.S. Government web pages and is in the public domain and may therefore be used freely by the public.  <I>(Space pho</I></FONT><I>tos are from the NASA JSC Digital Image Collection and 'Earth from Space'  Web sites.)  </I><FONT SIZE="1" COLOR="#000000" FACE="Arial" ><I>(Space photos are from t</I></FONT><I>he NASA JSC Digital Image Collection and "Earth from Space" Web sites.)</I></div> <bR> <div> _____________________________________</div> <bR> <bR> <div>  <A NAME="the_following_information_from_the"><IMG BORDER="0" SRC="1x1.gif" HEIGHT="1" ALIGN="bottom" WIDTH="1" HSPACE="0" VSPACE="0" ></A></div> <div> The following information from the <I><B>Great Lakes Atlas</B></I> is provided by the <B>U.S. EPA Great Lakes National Program Office</B>.
