may even disappear from view altogether.</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://starryskies.com/solar_system/mars/seasons_and_climate.html">It was once thought that these markings were vegetation, but we now know they 
are windblown dust.</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://starryskies.com/solar_system/mars/seasons_and_climate.html">When winter ensues, the polar cap of that hemisphere grows and may expand into 
the middle latitudes. The ice sheets of the polar caps are mainly carbon dioxide 
ice, but it is believed that there may be some water ice trapped underneath 
those sheets closest to the pole itself.</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://starryskies.com/solar_system/mars/seasons_and_climate.html">Generally Mars is quite cold with lows that reach -140 C (-220 F) but 
occasionally there are days that are quite balms reaching 20C (68 F.) Because 
soil and rock absorb heat from the Sun, the surface would be slightly warmer.</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/9B6080CA-7498-4DAE-829A-23661DF2887F/blog/" title="blog or email this clip"><img src="http://content8.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>
