GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The mid ocean ridge systems are the largest geological features on the planet. The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs from 87°N-about 333km south of the North Pole-to subantarctic Bourvet island at 54°S.

Detailed explanation-3: -Midocean ridges, transform faults and fracture zones are the key surface features produced by seafloor spreading.

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: -This makes Iceland very special and a popular place for geologists and scientists. The Mid-Atlantic Ridge is geologically significant because it marks the boundary where the North American and Eurasian tectonic plates meet and separate.
