Here's the breakdown of the Latin origins of "Pangaea" and "tectonics":

* Pangaea: This word comes from the combination of two Greek words:

* pan (meaning "all" or "entire")

* Gaia (meaning "Earth" or "Mother Earth")

So, Pangaea literally translates to "All Earth," referring to the supercontinent that existed millions of years ago.

* Tectonics: This word is derived from the Greek word τεκτονικός (tektonikos), which means "pertaining to building" or "relating to architecture."

In geology, "tectonics" refers to the large-scale movements and processes that shape the Earth's crust and upper mantle. The concept of tectonic plates building and rearranging the Earth's surface is reflected in the Greek origin of the word.
