When oceanic lithosphere subducts beneath oceanic lithosphere?
An island arc forms.
Does Rhyolitic magma forms beneath continental or oceanic crust?
continental crust
New oceanic lithosphere forms as a result of?
New oceanic lithosphere forms as a result of continental drift.
Earth does not get bigger as new oceanic crust forms?
Just as new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.
Where is basalt found on the earth's crust?
Basalt is found by comparing oceanic plates beneath the ocean floor.
What forms when one oceanic plate is forced beneath another plate a rift valley an ocean basin an ocean ridge a subduction zone?
a subduction zone
What forms when one oceanic plate is forced beneath another plate a. an ocean basin b. an ocean ridge c. a subduction zone d. a rift valley?
C. subduction zone

An island arc forms.
Does Rhyolitic magma forms beneath continental or oceanic crust?
continental crust
Describe how an island arc forms?
An island arc forms when two tectonic plates converge and one oceanic plate is forced beneath the other in a process known as subduction. The subducted plate melts, creating magma that rises to the surface and forms a volcanic arc of islands. This process is typically associated with ocean-ocean plate boundaries.
What occures when a continental and oceanic plate collide?
At some convergent boundaries, an oceanic plate collides with acontinental plate. Oceanic crust tends to be denser and thinner thancontinentalcrust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
How a subduction zone forms?
When two plates move together (at least one must be oceanic crust), one will sink beneath the other. The result is that a subduction zone forms between the two plates at the location where they meet.
New oceanic lithosphere forms as a result of?
New oceanic lithosphere forms as a result of continental drift.
Earth does not get bigger as new oceanic crust forms?

Where is basalt found on the earth's crust?

What type of rock makes up the continental and oceanic crust?
basalt forms in oceanic crust granite forms in continental
What forms when one plate is forced under another plate?
mid ocean ridge
