What type of boundary is crust not destroyed?
A crust is not destroyed at a divergent boundary, where tectonic plates move away from each other. This movement creates new crust as magma rises to the surface and solidifies.
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
Is crust being destroyed or created?
near ocean trenches.
How can the ocean crust be different ages?
On geologic time scales, new oceanic crust is constantly being formed ad mid-ocean ridges while older crust is destroyed at subduction zones. The crust forms at the ridge and is carried away by the movement of the plate as new crust forms to take its place. The oceanic crust is youngest new a mid ocean ridge and oldest far away from it.
When is crust neither formed or destroyed?
Crust is neither formed nor destroyed when the rate of crust formation at mid-ocean ridges equals the rate of crust destruction at subduction zones. This balance is known as isostasy and helps maintain the overall thickness of the Earth's crust.
Why is the oldest rock on planet earth found on continental plates not oceanic plates?
Oceanic crust is constantly being recycled. New oceanic crust is formed at mid ocean ridges while old ocean crust is destroyed at subduction zones. As a result there is little oceanic crust that is older than 200 million years. Continental crust does not get destroyed by subduction, so much of it has been around since the Precambrian time.
What is the land that stretches thousands of miles below the ocean?
The land that stretches thousands of miles below the ocean is known as the oceanic crust. It is composed of basaltic rock and is part of Earth's tectonic plates. This crust is constantly moving and being created at mid-ocean ridges while being destroyed at subduction zones.
Where would be logical places to look for crust being destroyed?
Logical places to look for crust being destroyed include subduction zones, where one tectonic plate is forced under another, leading to the recycling of crust into the mantle. Mid-ocean ridges are also significant, as they are sites of seafloor spreading, where new crust is formed and older crust can be pushed away and eventually destroyed. Additionally, continental collision zones can lead to crustal deformation and destruction through intense pressure and tectonic activity.

Yes
What is the thin part of the Earth's crust located under the ocean?
The thin part of the Earth's crust located under the ocean is called the oceanic crust. It is typically about 5 to 10 kilometers thick and is primarily composed of basaltic rocks, which are denser than the granitic rocks that make up the continental crust. The oceanic crust is formed at mid-ocean ridges through volcanic activity and is constantly being created and destroyed through tectonic processes.
