GEOLOGY

Detailed explanation-1: -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-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 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-4: -What are the steps in the process of sea-floor spreading? 1. A long crack in the oceanic crust forms at a mid ocean ridge.

Detailed explanation-5: -Answer and Explanation: The youngest seafloor rocks can be found on mid-ocean ridges, which form part of the ocean crust. Mid-ocean ridges are dynamic geographic features located in places where the Earth’s plates are pulling away from one another; they are continually producing new rocks.
