What happens when heavier oceanic crust converges with lighter crust at a deep ocean trench?
The heavier (usually older and cooler hence more dense) oceanic crust normally subducts (is forced under) the younger less dense crust.
In which layer of the Earth is the ocean floor?
The crust contains the ocean floor and also the continents on Earth.
What layers contain the least dense materials?
The least dense layer of the earth is the Crust , the mantle is second densest , whereas the core is the most dense layer of the earth
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Why does ocean crust far from a mid-ocean ridge subside?
It becomes more dense as it cools, until its density is greater than the asthenosphere below it.
What is the definition for ocean trenches?
Trenches are the lowest points on the crust of the Earth, created by the subduction of oceanic crust beneath less dense crust.
What kind of crust is found under the ocean?
oceanic crust
What happens when heavier oceanic crust converges with lighter crust at a deep ocean trench?
The heavier (usually older and cooler hence more dense) oceanic crust normally subducts (is forced under) the younger less dense crust.
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.
In which layer of the Earth is the ocean floor?
The crust contains the ocean floor and also the continents on Earth.
Where can the youngest oceanic crust be found?
The youngest oceanic crust can be found near the mid-ocean ridges.
What is two differences between the continental crust and oceanic crust?
The oceanic plate is thin, dense, and makes up the ocean floor. The continental plate is less-dense, thick, and make up the continents.
What layers contain the least dense materials?
The least dense layer of the earth is the Crust , the mantle is second densest , whereas the core is the most dense layer of the earth
Why does ocean crust from a mid-ocean ridge subside?
It becomes more dense as it cools, until its density is greater than the asthenosphere below it.
Were is the oceanic crust located?
It is found at the bottom of the ocean!
