What occurs when old oceanic crust is forced back into the mantle?
It will get pushed under the crust and then it will enter something called the subduction zone the plate that slides over the old crust will create either a volcano or a mountain and the old crust will turn into a trench or anything of that source. Hope it helped
Where is old seafloor destroyed?
Oceanic crust isn't destroyed because it's old; it is, in fact, destroyed due to destructive plate boundaries. This is where a continental plate and an oceanic plate move towards each other. As the oceanic crust is denser, it is pushed under the continental plate. Here it is forced into the mantle of the earth, where it is destroyed due to heat and convection currents.
In sea-floor spreading what happens to the old oceanic crust as new molten material rises from the mantle?
In sea-floor spreading, the old oceanic crust is pushed away from the mid-ocean ridge as new molten material rises from the mantle. As the new material solidifies, it forms new oceanic crust, leading to the spreading of the seafloor and the continuous creation of new crust. The older oceanic crust eventually gets subducted back into the mantle at tectonic plate boundaries.
Why is rock formed at th ridges called new rock?
Since the rock just came up and cooled, it's "new oceanic rock." Because... it's new rock. It's the youngest rock. It just came out of the ground and cooled, making it rock. Or Because new crust is being formed while the old crust is being pushed away.
Is crust being destroyed or created?
near ocean trenches.
Place where old crust is pushed down into a trench?
Subduction zone. This is where one tectonic plate is forced beneath another, leading to the recycling of old crust back into the mantle. The process can create deep ocean trenches and volcanic activity.

Where is old plate material destroyed?
Crust is destroyed (or recycled!) at convergent plate boundaries. Usually between oceanic and continental plates where subduction of the more dense oceanic crust occurs.

How far down does earths mantle go?
The Earth's mantle extends from the base of the crust down to a depth of about 2,900 kilometers (1,800 miles) at the boundary with the outer core. This region is divided into the upper mantle and lower mantle based on differences in composition and behavior.
How is crust destoyed?
Old crust can be destroyed bysubduction, or the pushing down of an oceanic plate below anoverriding plate at a convergent boundary. The initial phase of adivergent boundary is a rift valley, which progresses to form anoceanic basin with a mid-oceanic ridge.
How old is the Aleutian Trench?
It is about 20 million years old.
Where does the ocean floor go to after 180 million years?
Where old oceanic crust meets continental crust or younger oceanic crust at a convergent plate boundary it gets forced down into the mantle. This process does not necessarily happen when the crust is 180 millions years old. Rather, the oldest oceanic crust is found along the edges of the Atlantic ocean, dating to when it first formed in the Jurassic period.

How old is Brinsley Le Poer Trench?
Brinsley Le Poer Trench was born on September 18, 1911 and died on May 18, 1995. Brinsley Le Poer Trench would have been 83 years old at the time of death or 103 years old today.
Is crust being destroyed or created?
