New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
What else can I help you with?
Where are the youngest portion of Earth's crust found?
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
Is crust created or destroyed at the oceanic ridge?
Crust is created at oceanic ridges through volcanic activity where magma rises from the mantle and solidifies to form new oceanic crust. This process is known as seafloor spreading.
Why oceanic crust younger than the continental crust?
Oceanic crust is constantly created and recycled due to place tectonics. Oceanic crust is created by spreading ridges in the ocean floor and the oceanic plates subside under continental plates thus forcing it back down into the magma as the plate grows. Searching Oceanic Plate Tectonics on google will provide images that made this easier to understand.
What are four differences between the oceanic crust and the continental crust?
1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.
What is created at a mid ocean ridge?
New oceanic crust.
Is ocean crust or landform crust yonger?
Ocean crust is younger than landform crust. Oceanic crust is constantly being created at mid-ocean ridges through volcanic activity, making it much younger in comparison to the older landform crust found on continents.
How are oceanic crust and continental crust different?
Oceanic crust is denser and thinner than continental crust. Oceanic crust is primarily made up of basalt rock, while continental crust is composed of lighter granite rock. Additionally, oceanic crust is constantly being created and destroyed through seafloor spreading and subduction processes, whereas continental crust is relatively stable.
Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
Is the oceanic crust felsic or mafic?
Oceanic crust is mafic.
What does it mean if the oceanic crust 0?
the oceanic crust is 0.
What crust is more dense oceanic or continental crust?
Oceanic crust is significantly denser.
