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

Why must old crustal material be destroyed at convergent plate boundaries?
Because either one plate is pushed downward into the mantle, where it melts, or two plates of similar density crush together, fusing the rocks from either side into one mass. The Himalayas have many fine examples of the latter scenario, though I think your question was more about the first.
What do you call a plate boundary in which no new crust is made or destroyed?
recessive plate boundary
What is an image made after a plate is destroyed?
Cancellation print.
Where is most lithosphere created?
New lithosphere is created at divergent plate margins.
Why isn't new oceanic crust generated along volcanic island arcs?
At a volcanic island arc, an oceanic plate slides into the mantle and thus oceanic crust is destroyed. The volcanoes add material on to of the crust, but to not cause the crust to expand outward.
How and where material is destroyed in the earth's crust?
I believe it is destoryed along a convergent plate boundry where one plate slides underneath another.
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.
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.
What is the plate boundary where oceanic crust is destroyed?
its destroyed on avi face
How do you calculate the weight of 200X200X10 mm plate?
The answer depends on the material of the plate and the density of that material.

What material is this plate made of?
The material the mounting plate is made of is plated steel. To provide stability in the product.
How are fossils naturally destroyed by plate tectonics?
they are crushed
What is an image made after a plate is destroyed?
Cancellation print.
Is crust formed or destroyed at each type of plate boundary?
Divergent: Created Collision\Subduction: Destroyed
