Where did the crust from the earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.
Does the magma and lava from a volcano come from the mantle?
Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.
What are oceanic plates made up of?
Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.Oceanic crust is primarily composed of mafic rocks, or sima, which is rich in iron and magnesium.It is thinner than continental crust, or sial, generally less than 10 kilometers thick, however it is denser, having a mean density of about 2.9 grams per cubic centimeter.[1]
Do volcanic islands form where two oceanic plates push together?
no they come when magma erupts from under the ocean
What happen to oceanic crust at deep ocean trench?
At a deep oceanic trench the marine tectonic plate (oceanic crust) is carried (the word is subducted) beneath another tectonic plate (usually but not always - continental crust) and it sinks hundreds of miles into the Earth's Mantle. The cold wet oceanic crust is heated as it sinks and remelts to form magmas which come up 'landward' of the trench forming a string of volcanoes (an island arc). As all the margins of the Pacific Ocean are being subducted the volcanes formed are called the 'fiery ring of the pacific'. See the related links below.
What happens when to plates collided?
When two plates collide, or come together, the plates will push upward, forming a mountain. If one plate is continental crust and the other is oceanic crust, the less dense crust (this being the oceanic) will actually move under the more dense crust, in a process called subduction, to form a deep-ocean trench.
What happens to Rocks when plates collide?
When two plates collide, or come together, the plates will push upward, forming a mountain. If one plate is continental crust and the other is oceanic crust, the less dense crust (this being the oceanic) will actually move under the more dense crust, in a process called subduction, to form a deep-ocean trench.
Where did the crust on the Earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.

In sea floor spreading where does new crust come from?
From Ali (i am not a member yet) it comes from oceanic crust thanks
Where do valcanoes come from?
From the colliding plates called Plate Tectonics which two continental crust/ two oceanic crust/ continental - oceanic crust will collide then the one that is denser will go in the mantle that we called Subduction after that happens the one continental crust will go upward until volcano will formed that is called Upthrust Faulting. It is either the crust will form mountain or volcano but it depends upon the pressure in the mantle that makes the landform to have a Magma Chamber
How does new oceanic crust form at a divergent boundary?
According to Google, Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary
When oceanic plates come together what land form does this event create?
is found in to mountain
