The continuous mountain range formed from seafloor spreading is called the Mid-Ocean Ridge.

Here's why:

* Seafloor Spreading: This process occurs at divergent plate boundaries where magma from the Earth's mantle rises to the surface. The magma cools and solidifies, creating new oceanic crust.

* Mid-Ocean Ridge: This is a vast undersea mountain range that runs for over 40,000 miles (64,000 kilometers) through all the world's oceans. It's the longest mountain range on Earth and is where most of Earth's new crust is created.
