Happy Studying! 




The concept of sea-floor spreading process involves splitting of tectonic plates . Tectonic plates are slabs of Earth's lithosphere in large sizes. The sea floor spreading also involves the formation of underwater mountains.

Sea-floor Spreading

  • This process is a geological process.Tectonic plates breaks or get seperated.

  • Less denser material rises above resulting in formation of seafloor mountain.

  • The crust of the floor cracks forming mountains and the new floor of the ocean is created.

  • Such new sea floor is called mid ocean ridge.

Therefore the chain of underwater mountains along which sea-floor spreading occurs is a Mid ocean ridge.
