The earth plays hardball

So it seems to some scientist that at one point, the Earth began life with a hard shell (kind of like a turtle shell) that later developed into the plate tectonics we know today. This is however, just the latest study done in a long-standing debate about plate tectonics and earth.

You can read about the study in the article entitled “Earth probably began with a solid shell: New research suggests that plate tectonics began later in Earth’s history” at Science Daily, courtesy of the University of Maryland . Something tells me that this debate will continue for a while.
