The granite or granitelike layer of the continental crust extends beneath the ridge to the vicinity of the trench. Basaltic magmas, generated in the mantle beneath the ridge, rise along fractures through the granitic layer. These magmas commonly will be modified or changed in composition during passage through the granitic layer and erupt on the surface to form volcanoes built largely of nonbasaltic rocks'. </font><br><br><table><tr><td>Previous 5 Terms: <br><a href="iseidomal .html"><font color=green>iseidomal </font></a><br> <a href="isentropic .html"><font color=green>isentropic </font></a><br> <a href="Isentropic Analysis.html"><font color=green>Isentropic Analysis</font></a><br> <a href="Isentropic Lift.html"><font color=green>Isentropic Lift</font></a><br> <a href="Isentropic Surface.html"><font color=green>Isentropic Surface</font></a><br></td><td> </td><td><align="right">Next 5 Terms:<br> <a href="islandic .html"><font color=green>islandic </font></a><br> <a href="ISO .html"><font color=green>ISO </font></a><br> <a href="Isobar.html"><font color=green>Isobar</font></a><br> <a href="isobar .html"><font color=green>isobar </font></a><br> <a href="Isobaric Chart.html"><font color=green>Isobaric Chart</font></a><br></td></tr></table> <br></left><center> </font> <br></center><left><font size="1" face="tt"> <div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script><fb:comments href="http://TeachMeFinance.com/Scientific_Terms/%%srfile%%" num_posts="2" width="500"></fb:comments><br> <br> <h2>About the author</h2> <table><tbody><tr><td> <img alt="Mark McCracken" src="http://markmccracken.com/markmccrackenface.jpg" class="avatar avatar-128 photo" height="128" width="128"></td><td><h5><a href="https://plus.google.com/u/0/112243849435091136578" rel="author">Mark McCracken</a></h5> <p>Author: Mark McCracken is a corporate trainer and author living in Higashi Osaka, Japan.
