How does the age of oceanic crust compare to the age of continental crust?
Oceanic crust is generally younger than continental crust. Oceanic crust is continuously formed at mid-ocean ridges through volcanic activity and then gradually moves away from the ridge, undergoing processes that make it relatively young compared to the older continental crust.
What is the difference between continential and oceanic crust?
Continental crust is thicker, less dense, and typically older than oceanic crust. Oceanic crust is thinner, more dense, and younger as it is constantly being formed at mid-ocean ridges and being recycled at subduction zones.
Oceanic crust is what than continental crust?
Oceanic crust is denser and thinner than continental crust. It is mainly composed of basalt, while continental crust is primarily made up of granite. Oceanic crust is also younger and constantly being formed at mid-ocean ridges through volcanic activity.
Which is thicker continental crust or oceanic crust?
Continental crust is generally thicker than oceanic crust. Continental crust can range from 20 to 70 kilometers thick, while oceanic crust is typically around 7 to 10 kilometers thick. This is due to differences in composition and the processes by which they are formed.
What is continental and oceanic crust?
Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
What formed when lava cools and crystallizes on top of oceanic crust?
it becomes part of the oceanic crust
Is a new oceanic crust formed at a transform fault boundary?
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at the sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
How does trench formed?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
Which feature is commonly formed at a plate boundary where oceanic crust converges with continental crust?
A deep ocean trench is commonly formed at a plate boundary where oceanic crust converges with continental crust. The oceanic crust is denser and is forced beneath the lighter continental crust, creating a deep trench.
How does the age of oceanic crust compare to the age of continental crust?
Oceanic crust is generally younger than continental crust. Oceanic crust is continuously formed at mid-ocean ridges through volcanic activity and then gradually moves away from the ridge, undergoing processes that make it relatively young compared to the older continental crust.
What is the new oceanic crust formed by?
Magma leaking in from the mantle.
When two geologic plates are moving away from each other what happens?
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.
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.
What is the difference between continential and oceanic crust?
Continental crust is thicker, less dense, and typically older than oceanic crust. Oceanic crust is thinner, more dense, and younger as it is constantly being formed at mid-ocean ridges and being recycled at subduction zones.
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.
