The boundary between continental crust and oceanic crust occurs at the base of the?
The boundary between continental crust and oceanic crust occurs at the base of the lithosphere. This boundary is known as the Mohorovičić discontinuity, or Moho. It separates the less dense continental crust from the more dense oceanic crust below.
What are the two types of crust on the earth?
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
What is the difference of continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
What are 2 kinds of crust?
crust on a pizza (thin & thick) or the earth's crust
Which type of crust is primarily made of basalt and is more dense?
Oceanic crust is primarily made of basalt and is more dense than continental crust. It is also younger and thinner compared to continental crust.
The boundary between continental crust and oceanic crust occurs at the base of the?
The boundary between continental crust and oceanic crust occurs at the base of the lithosphere. This boundary is known as the Mohorovičić discontinuity, or Moho. It separates the less dense continental crust from the more dense oceanic crust below.
Why does ocean crust dive below continental crust?
The ocean crust dives below the continental crust due to a collision. This collision involves the two types of crust and since the oceanic crust is denser, it sinks to the bottom while the less dense continental crust rises to the top.
Why does the oceanic crust move below continental crust?
The basaltic oceanic crust is more dense than the granitic continental crust. Therefore, when the two meet at plate margins, the oceanic crust usually subducts beneath the continental plate.
What is difference of the continental crust and the oceanic crust?
Continental crust is thicker but less dense, and oceanic crust is thinner but more dense, making it heavier.
What layer of the crust is the most dense?
Oceanic crust is more dense than continental crust.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
What is the difference between contiental crust and oceanic crust?
Continental crust is on top of the oceanic crust Continental crust is made of granite whereas oceanic crust is made of basalt Continental crust is partly above sea level and partly below whereas oceanic crust is always below sea level.
What are the two types of lithoperic crust?
The two types of lithospheric crust are continental crust, which is thicker and less dense than oceanic crust, and oceanic crust, which is thinner and more dense than continental crust.
What are the two types of crust on the earth?
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
Is the oceanic crust dense?
Yes. It is more dense than continental crust.
Why does continental crust always stay at or near the surface of the earth?
There are several reasons - continental crust is less dense than the magma below - also - through a process known as Isostatic Equilibrium the continental crust maintains its level above the mantle. When oceanic crust contacts continental crust at plate boundaries there is a subduction zone where the oceanic crust is pushed under the continental crust because is it much thinner and less massive.
Why does the continental crust float higher on the athenosphere than oceanic crust?
The continental crust is less dense and thicker than oceanic crust, allowing it to float higher on the asthenosphere. This is because the continental crust is composed of less dense rock types like granite, while the oceanic crust is made up of denser basalt. As a result, the less dense continental crust floats higher due to its lower density and greater thickness compared to oceanic crust.
