Yes! When two oceanic plates collide, one of the plates subducts beneath the other. As the subducting plate sinks, it releases volatiles (such as carbon dioxide and water) into the mantle. This addition causes the mantle to melt in the places where it mixes with volatiles. The melted mantle is less dense than the surrounding mantle, so it slowly rises until it reaches the surface. When the melted mantle reaches the surface, it is considered a volcano. Over many years, these volcanoes build up the sea floor and may eventually break the surface. Now, these volcanoes have become volcanic islands, and usually occur as a string (an arc) of volcanic islands that follow the plate boundary.
What else can I help you with?
What region is basalt rock found in?
Basalt rock is found in regions with volcanic activity, such as along divergent plate boundaries, hotspots, and oceanic islands like Hawaii. Basalt is a common type of volcanic rock that forms from the rapid cooling of lava.
New crust forms what kind of new boundaries?
New crust forms at divergent boundaries, where tectonic plates move away from each other. This process can occur in oceanic or continental crust.
What forms at diverging plate boundaries?
At diverging plate boundaries, new oceanic crust forms through seafloor spreading. Magma rises to the surface and solidifies, creating mid-ocean ridges. As the plates move apart, they create new oceanic crust, which can lead to the formation of rift valleys.
Forms when two Crustal Lithospheric Plates come together?
A convergent boundary is formed when two crustal lithospheric plates collide. This collision can result in the formation of mountain ranges, deep ocean trenches, and volcanic arcs. The type of convergent boundary that forms depends on the type of crust involved in the collision (oceanic or continental).
What do convergent plate boundary form?
Convergent plate boundaries can occur as a continental-continental, continental-oceanic, or oceanic-oceanic crust collision. A continental-continental collisions will typically result in a mountain range formation, such as the Himalayan Mountain Range. A continental-oceanic converging plate boundary will result in the more dense oceanic crust subducting beneath the less dense continental crust. The subduction zone leads to volcano formation from melting rock within the asthenosphere, beneath the continental crust. An example of this boundary is the west coast of the United States. An oceanic-oceanic converging plate boundary will typically result in one oceanic slab "sliding" beneath the other, due to only slight differences in density. This may form a volcanic island arc on the ocean floor, but may not necessarily reach above sea level.
What are two ways volcanoes can forms near converging plate boundaries?
Volcanoes may form where two oceanic plates collide or where an oceanic plate collides with a continental plate.
A mid-ocean ridge forms along what plates?
A mid-ocean ridge forms along divergent plate boundaries, where tectonic plates are moving apart. These boundaries occur where magma rises to the surface, creating new oceanic crust and extending the ocean floor.
What forms where a oceanic plate begins to move down in a subduction zone?
Convergent Boundaries
What feature forms at diverging oceanic plates?
Mid-ocean ridges form at diverging oceanic plates. As the plates move apart, magma rises to fill the space, creating new oceanic crust. This process results in the formation of underwater mountain ranges along the divergent boundary.
Is true or false oceanic lithosphere is created at divergent boundaries?
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
What region is basalt rock found in?

This type of boundary forms when two oceanic plates collide.?

What is the sea floor spreading theory?
Theory that oceanic crust forms along submarine mountain zones, known collectively as the oceanic ridge system, and spreads out laterally away from them.
