Their underground plumbing consists of unconstricted chambers of varying sizes. Water, which has been superheated far underground, rises along tiny cracks, flows into larger channels and eventually reaches the earth's surface. <BR><BR>"Unlike geysers, water convection is continuous within hot spring pools. Hot surface water sinks while hotter, superheated water continues to rise. This circulation keeps water below the temperature needed to begin the chain reaction leading to an eruption." <BR></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.cnet.com/2300-13576_3-10001234-6.html?tag=mncol"><P aria-level="0" aria-posinset="0" aria-setsize="0"><STRONG aria-level="0" aria-posinset="0" aria-setsize="0">Photo by</STRONG> Daniel Terdiman/CNET</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/7D713D9F-7504-456D-8222-B006C35EE1A2/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
