The major ridges in the oceans are most likely formed by the slow eruption of magma from the underlying mantle through a separating rift between two tectonic plates. When the magma contacts the ocean water the magma cools and solidifies into new rock.

Mid-ocean ridges are actually underwater mountain ranges.?

It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.

How are ridges formed on the ocean floor?

Ocean current paths of travel, underwater volcanoes, tectonic plate movement, depends which specific ridges you are talking about.


The spreading of the ocean floor is what?

At the mid-ocean ridges, large underwater mountain ranges formed along diverging oceanic plates.


What is ocean ridges formed by?

An ocean ridge is and underwater mountain range which is formed in the same way as an above water mountain range, by plate tectonics.


Mid ocean ridges are actually underwater mountain ranges?

Yes, mid-ocean ridges are underwater mountain ranges that form where tectonic plates are spreading apart. Magma rises up to fill the gap between the plates, creating new oceanic crust. This process contributes to the overall process of seafloor spreading.


What are underwater mountains called?

Underwater mountains are called seamounts. They are elevated underwater mountains that do not reach the water's surface. Seamounts are formed by volcanic activity or tectonic forces and can support diverse marine ecosystems.


Mid-ocean ridges are actually underwater mountain ranges true or false?

True. Mid-ocean ridges are underwater mountain ranges formed by tectonic activity along the ocean floor. They are characterized by volcanic activity and are where new oceanic crust is created as tectonic plates move apart.


True or False Mid-ocean ridges are actually underwater mountain ranges?

It is true that mid-ocean ridges are underwater mountain ranges. These ridges are long, seismically active submarine ridges associated with seafloor spreading.


What is the definition of rifts and ridges?

Rifts are long cracks in the Earth's crust caused by tectonic activity that can lead to the formation of new ocean basins. Ridges are underwater mountain ranges formed by the upwelling of magma at divergent plate boundaries. Both rifts and ridges are associated with the process of seafloor spreading.


What features do great underwater mountain ranges exist?
