Web• The deep seafloor between 4000 and 6000 m water depth • Covers roughly 30% of the Earth’s surface • One of the flattest places on Earth (<0.05 degree slope), generally flatter than the continental shelf but there is topography: – Abyssal hills (< 1 km above the seafloor) – Seamounts - volcano’s that are > 1 km above the seafloor ... WebWhat will happen when seafloor spreading occurs? Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. ...
