WebbIn 1962 Hess proposed that the seafloor was created at mid-ocean ridges, spreading in both directions from the ridge system. At the spreading center, liquid rock called basaltic magma rises from the earth's mantle as it upwells beneath the spreading axis. When the magma hardens, it forms new oceanic crust that becomes welded to the original crust. WebbShe stretched out her hand, mere centimeters between her and Helaena’s unconscious body. The water swirled around them, and a sense of calm washed over her as she felt the call flow in and out of her, the arcane energy spreading over her skin. Why do you fight? She froze, fingertips brushing Helaena’s arm.
