I figure it might be warm enough to have some molten rock even if that is not enough (especially in iron content) to start the dynamo effect that would create a global magnetic field. Since the field is not present, either iron is missing from the core or it is cold enough to limit the molten part.<br /><br />Given the size of select Martian features like Olympus Mons, the Tharsis Bulge, and a certain canyon; I think we can eliminate the possibility of tectonic plates. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>
