What is plate under the ocean?

The lithosphere is fragmented into a dozen of huge irregularly shaped pieces called tectonic plates which are in constant motion and slide over under and past each other on top of the partly molten inner layer. There are two kinds of plates: oceanic crust (i.e. the plates under the ocean) and continental crust.

Can Pangea happen again?

The answer is yes. Pangaea wasn’t the first supercontinent to form during Earth’s 4.5-billion-year geologic history and it won’t be the last. … So there’s no reason to think that another supercontinent won’t form in the future Mitchell said.
