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.
Answer:
50,000 years
Explanation:
rate of deposition of clay is 1mm per 1000 years so for 5cm or 50mm of ooze it will take 50×1000 years= 50,000 years.
