Answer:
From the statements mentioned about Convergent Boudaries we can select the following as true.
- Convergent boundaries are where two plates move toward each other. By definition this statement is true.
- New oceanic plate (oceanic lithosphere) is created at convergent boundaries. True, a new oceanic plate can form from the action of convergent boundaries at midocean, lava and million of years do the remaining job.
- Convergent boundaries that have subduction occurring provide a "pull" force that contributes to plate motion. False, Subducting melt and ascend trough the rock creating a volcanic eruption cone and producing an island chain.
- Oceanic plates can be destroyed at convergent boundaries due to subduction. False, The older plate will subduct due to its density and it is forced deep into the mantle, it will melt once the deepth is reached.
The true statement is - B. The rock cycle is powered by the movement of tectonic plates.
Almost all rocks on our planet came to existence because of the tectonic activity. The movement of the tectonic plates is enabling the magma from the mantle layer to come to the surface, cool off, and create new layers of rocks. On the other hand, the same process, where there's subdustion zones, is moving the existing rocks down into the mantle layer where they are ''recycled'' in way, and this process is continuing to happen all the time.
