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. Eventually, the crust cracks. • Sea floor spreading • geography • Geomorphology • Ocean crust formation • Ridge • NCERT • For any doubt related to your studies just give me a msg on my instagram- / rudraksh18 • Our facebook page- / smartprepforgovtexams • Join our telegram group for more updates • t.me/upscpscvideos
