The mid-ocean ridges are divergent plate boundaries-areas where earth's lithospheric plates are moving away from each other. This movement causes the crust to "thin out". The thinning allows the magma to come to the surface in the form of volcanoes.
Mid-ocean ridge volcanism is just one part of the larger, all-encompassing, and evolving theory of plate tectonics. The production of lava and new crust at the mid-ocean ridges is largely a reaction to gravity induced subduction of oceanic crust at convergent plate boundaries.

What else can I help you with?
Do most of the volcanoes of the mid-ocean ridge rise above the oceans surface?
No, most of the volcanoes along the mid-ocean ridge do not rise above the ocean's surface. These submarine volcanoes are typically under the water and form part of the continuous volcanic activity that occurs along the ocean ridges. Only a few volcanoes along the mid-ocean ridge, such as Iceland, rise above the ocean's surface.
Do volcanoes form along mid ocean ridges where two plates move together?
Volcanoes that form along a mid-ocean ridge are called volcanic islands. These volcanoes occur when the plates move apart to produce gaps which molten lava rises to fill.
Volcanoes that form along a mid-ocean ridge occur a diverging plate boundary?
Volcanoes that form along a mid-ocean ridge are called volcanic islands. These volcanoes occur when the plates move apart to produce gaps which molten lava rises to fill.
Is Iceland mostly volcanoes?
iceland is a belt of volcanoes/hotspots along the mid ocean ridge, it isn't just mostly volcanoes, it is a volcano itself
Which of these would be indications that a given mountain range was not formed by subduction?
It is not along an ocean coastline. There are no volcanoes.
What would happen if volcanic eruptions continued to occur on the sea floor?
There are volcanoes along the floor of the ocean that form a trench. When these volcanoes erupt, it can cause tectonic movements.
What is the definition a string of islands formed by the volcanoes along a deep ocean trench?
A string of islands formed by volcanoes along a deep ocean trench is known as an "island arc." This geological formation occurs when tectonic plates converge, leading to subduction, where one plate moves under another. The intense heat and pressure from the subduction process cause melting of the mantle, resulting in volcanic activity that creates islands. These islands often exhibit a curved shape, following the contour of the trench.
Where are volcanoes most likely formed?
mostly around the pacific ocean
The Ring of Fire is a long belt of volcanoes that nearly circles the Pacific Ocean What process formed these volcanoes?
Convergent plate volcanism
How many volcanoes are in the ocean?
There are approximately 1,500 active volcanoes in the world, and around 90% of them are located in the oceans. The majority of these underwater volcanoes are found along tectonic plate boundaries in regions known as the Ring of Fire and the Mid-Ocean Ridge.
Volcanoes that form along mid-ocean ridges occur at?
Volcanoes that form along mid-ocean ridges occur at divergent tectonic plate boundaries, where two plates are moving away from each other. Magma rises to the surface through the cracks created by the diverging plates, resulting in the formation of underwater volcanoes.
Can volcanoes from on the ocean floor?
yes it can. it rarely happens though and can cause earthquakes and other features
