The fate of oceanic plates is destruction via subduction and reabsorption into the mantle,whereas continents float about on the asthenosphere in perpetuity.

Question

Quizplus · Accepted Answer

This is correct, as oceanic plates are denser and heavier than continental plates, they tend to sink and get reabsorbed into the mantle through subduction zones. Continents, on the other hand, are made of lighter materials and are generally too buoyant to subduct. Hence, they tend to drift around the asthenosphere for millions of years without getting destroyed.
