Scientists believe that the earth&#39;s bulge is growing at the equator. What does this indicate? What causes it? What do scientists understand from it? This NASA page is a fascinating journey of exploration into the earth&#39;s center of gravity.]]></description><category>Exploring Gravity</category><author>sunny</author><pubDate>Thu, 29 Mar 2007 07:17:38 -0700</pubDate><guid isPermalink="false">trailfire:markId:78869</guid></item><item><title>ScienceDaily: Earth&amp;#039;s Gravity Scar</title><link>http://trailfire.com/sunny/marks/78877</link><description><![CDATA[Can an earthquake scar earth? Yes, in more ways than one. In this case, the Sumatran earthquake scarred the earth&#39;s gravity! How did this happen, and what does it mean for the earth? This article describes the event and how earth underwent change in an instant.]]></description><category>Exploring Gravity</category><author>sunny</author><pubDate>Thu, 29 Mar 2007 07:32:57 -0700</pubDate><guid isPermalink="false">trailfire:markId:78877</guid></item><item><title>JPL.NASA.GOV: Feature Stories</title><link>http://trailfire.com/sunny/marks/78880</link><description><![CDATA[Why do scientists study gravity? Dr. Watkins answers this basic question. Read here also about how GRACE (Gravity Recovery and Climate Experiment) will measure the earth&#39;s gravity field. The future tense is for a dated article.
