Oceanic Crust is denser that continental crust. Bassically the Oceanic crust is made with volcanic rocks and intrussions from the Mantle (which is more dense than the crust) and it has densities of about 2.9 grams/cubic centimeter.
Q. When two plates collide the oceanic crust usually subducts beneath the continental crust because it is?
When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. Once again a benioff zone forms where there are shallow intermediate and deep focus earthquakes.

Q. Which Subducts faster continental crust or oceanic crust?
Oceanic plates move faster than continental plates. o Oceanic plates tend to have ridges (pushing) and attached subducting slabs (pulling). o At the base of oceanic plates in the LVZ (low velocity zone), a region of partial melting that provides ‘lubrication” at the base of the plates. Subduction Rules.
Q. What are three differences between continental and oceanic crust?
Continental crust is low in density whereas oceanic crust has a higher density. continental crust is thicker, on the contrary, the oceanic crust is thinner. Continental crust floats on magma freely but oceanic crust floats on magma scarcely. Continental crust cannot recycle whereas oceanic crust can recycle it.
Q. What are the characteristics of continental crust?
Continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm.
Q. What are the 2 main types of crust?
Earth’s crust is divided into two types: oceanic crust and continental crust.
Q. Why is the oceanic crust so dense and heavy?
In the theory of tectonic plates, at a convergent boundary between a continental plate and an oceanic plate, the denser plate usually subducts underneath the less dense plate. It is well known that oceanic plates subduct under continental plates, and therefore oceanic plates are more dense than continental plates.
Q. Which core is more dense?
inner core
Q. Do we live inside or on top of the earth?
Earth is the planet we live on. It is the only planet in the Solar System with liquid water on its surface. It is also the only planet we know to have life on it. Earth is also known as Terra.
Q. Do we live on the inside of Earth?
I repeat on earth. We do live on its surface not underneath so we live on its surface. We swim in pool of water, cause we don’t swim on the water surface , only dead ones float on the water due to gases built up inside the body , other than that we swim in, cz inside the water but not on its surface.
