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.
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 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]
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).
When two plates come together?
They fold up when there continental, creating mountains and steep hills. The Rocky's are a great example. Oceanic plate collisions cause tsunamis, and Oceanic plates are subducted under Continental plates, they are overlapped by the continental plate.
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.

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
What happens when oceanic and oceanic crust meets?
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
In sea floor spreading where does new crust come from?
New crust is formed at mid-ocean ridges through the upwelling of magma from the mantle. As plates move apart, the magma solidifies and creates new oceanic crust. This process is part of the theory of plate tectonics and helps drive the movement of Earth's lithospheric plates.
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?
When oceanic plates come together, they create a subduction zone where one plate is forced beneath the other. This process forms deep ocean trenches and can lead to the formation of volcanic arcs and islands.

How can such heavy things as the continents float?
Continents float because the rock beneath them is denser then the surface rocks The surface rocks are poorer in iron than the deeper layers. The continents are made mostly of silica rich rock, which is less dense than oceanic crust, so when the two come in contact, the oceanic crust sinks beneath the continent.
What happens when silence and space come together?
You get to relax....
