GEOLOGY

Detailed explanation-1: -At a mid-ocean ridge, molten material rises from the mantle and erupts. The molten material then spreads out, pushing older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock (new ocean floor) in the center of the ridge.

Detailed explanation-2: -Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

Detailed explanation-3: -The material that erupts at spreading centers along the mid-ocean ridge is primarily basalt, the most common rock on Earth. Because this spreading occurs on a sphere, the rate separation along the mid-ocean ridge varies around the globe.

Detailed explanation-4: -Seafloor spreading or Seafloor spread is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Detailed explanation-5: -Old oceanic crust melts as it sinks back into the mantle Because it is less dense than the surrounding rock, molten. material from the mantle rises through the crust toward cracks in the ocean floor.
