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 happens with convergent boundaries?
Convergent boundaries are also known as destructive plates. In this region, active volcanic activities, earthquakes, and crustal deformations are always happening.
Forms when two Crustal Lithospheric Plates come together?
The Convergent/Converging Boundaries
What are three mechanisms of crustal thickening that occur at convergent boundaries?
Three mechanisms for crustal thickening are magmatic intrusion, sedimentation, and faulting.
Why are divergent boundary considered constructive while convergent boundaries considered destructive?
divergent - creates new crustal rockconvergent - destroys old crustal rock
What is the term for a piece of crust which has been in a collision along a convergent crustal boundary and become accreted to another crustal plate?
terrane

What is a crustal boundary?
There are 3 types convergent, divergent, and transform boundaries. Convergent collide, divergent move away, and transform boundaries occur when two boundaries pass each other horizontally. The process of subduction is associated with convergent boundaries and tectonic plates play a huge role in these types of boundaries.

What boundaries are convergent and divergent?
Boundaries, or faults, are locations on the edges of plates, crustal masses that are very slowly moving atop the convective outer mantle (asthenosphere).At convergent boundaries, two crustal masses (plates) are pushing into each other. This can result in subduction, so may be a destructive boundary.At divergent boundaries, two masses of rock are pulling away from each other. This can be a constructive boundary when it produces rifting and seafloor spreading.At transform boundaries, or transform faults, rock masses move past one another. These are known as conservativeboundaries because crust is neither destroyed or created.(these can cause earthquakes when accumulated strain is released)

What happens to magma divergent boundaries?
At divergent boundaries, two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below.
What change earth surface?
Convection currents beneath the tectonic plates of the crustal surface of the earth provide heat from the core in circular motions, and make plate boundaries move together from compressional forces at convergent boundaries, apart from tensional forces at divergent boundaries, and side by side from shear force at transform boundaries.
