The new oceanic crust is from the mid-ocean ridge, located at the bottom of the sea floor. The mid-ocean risge is a divergent boundary where hot rock flows through forming what is called 'pillow formations' that look like they were squeezed out of a tube of toothpaste, since they are lumps of rock that pile over one another. These pillow formations smooth out as they move away from the mid-ocean ridge. The reason that the oceanic crust hasn't covered the Earth entirely is that there are these things called deep-ocean trenches, where dense, oceanic crust sinks under less dense continental crust.
What else can I help you with?
Where is new silicon mined?
silicon is mined in near the earths crust, and it is also is made of 27.7% earths crust hope this helps
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
Where is most of the earths new crust found?
Most of Earth's new crust is found along mid-ocean ridges, underwater mountain ranges where tectonic plates are moving apart. This is where magma rises from the mantle to create new crust through volcanic activity.
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
What has to happen before rock from the earths mantle becomes new piece of crust?
It has to harden
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
