Answer:
Step-by-step explanation:
The feature of Earth created at mid-ocean ridges is called a divergent boundary or a spreading center. This is where two tectonic plates are moving away from each other, allowing magma to rise up from the mantle and create new oceanic crust. As the magma cools and solidifies, it forms a series of mountains and ridges on the seafloor. The continuous process of seafloor spreading at mid-ocean ridges is one of the driving forces behind the movement of tectonic plates and the changing shape of the Earth's surface over geologic time.
