The age of material on a tectonic plate depends in part on what type of crust it is composed

The age of material on a tectonic plate depends in part on what type of crust it is composed of. 1. (continental crust/ ocean floor/ oceanic crust) tends to be younger because it is continually produced at the 2. (mid-oceanic ridges/ hot spots/deep sea vents) and then recycled. On the other hand, 3. (continental crust/ ocean floor/ oceanic crust) tends to be older because it can often remain intact for longer periods.
