What else can I help you with?
Is the oceanic lithosphere denser?
No. Oceanic plates are denser than conitnental plates.
What can form when one oceanic plate subducts under another oceanic plate?
Tectonic
Differences between oceanic-oceanic and oceanic-continental subduction boundary?
In an oceanic-oceanic subduction boundary, one oceanic plate subducts beneath another oceanic plate. This process can result in volcanic island arcs being formed. In an oceanic-continental subduction boundary, an oceanic plate subducts beneath a continental plate. This can lead to the formation of volcanic mountain ranges on the continental plate.
Why does oceanic lithosphere sink at subduction zones but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
What are the Convergent plate boundaries can be in 3 different settings?
Convergent plate boundaries can occur in three main settings: oceanic-continental, oceanic-oceanic, and continental-continental. In oceanic-continental settings, an oceanic plate subducts beneath a continental plate, leading to volcanic arcs and mountain ranges. In oceanic-oceanic settings, one oceanic plate subducts under another, forming island arcs and deep ocean trenches. In continental-continental settings, two continental plates collide, resulting in the formation of large mountain ranges, such as the Himalayas.

Is the lithosphere thinner under the oceanic or continental crust?
The lithosphere is generally thinner under oceanic crust compared to continental crust. Oceanic lithosphere is typically around 5-10 kilometers thick, while continental lithosphere can be up to 200 kilometers thick. This difference is due to variations in temperature and composition between the two types of crust.
Do the pacific plate have more oceanic lithosphere or more continental lithosphere?
Oceanic. Most of the Pacific plate is under the Pacific Ocean.
Why does oceanic lithosphere sink at subduction zones but not at mid ocean ridges?

How does plate movement occur in trenches?
That's a hotly debated question among scientists. We do know that trenches form where oceanic lithosphere subducts under continental lithosphere. as to what drives the plates together, it is probably continents being moved by the currents of the partially liquified asthenosphere below it. Many scientists think that it is the weight of the oceanic lithosphere being pulled by gravity and pushed from the higher mid-ocean ridges. To me that seems a bit like a chihuahua pulling a house.
Where slab of oceanic lithosphere are subducted under continental lithosphere?
Oceanic lithosphere is subducted under continental lithosphere at convergent plate boundaries. This process occurs when the denser oceanic plate sinks beneath the less dense continental plate, creating deep ocean trenches and volcanic arcs. The subducted oceanic plate eventually melts and contributes to the formation of magma that leads to volcanic activity.
How do island arcs form?
Everytime a volcano erupts, the magma gets higher and higher everytime it hardens. This causes an island arc
Why does oceanic lithosphere sink at subduction but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
What is the effect when a oceanic plate meets a continental plate?
the oceanic plate subducts under the continental plate and then melts in the mantle and often will create volcanos along the conitinental plate.\
