What is pangaea definition?

Pangaea is a term used to describe a hypothetical supercontinent that existed millions of years ago. It is believed that Pangaea formed about 300 million years ago during the Paleozoic era, and broke apart about 175 million years ago during the Mesozoic era. The concept of Pangaea was first proposed by Alfred Wegener, a German scientist, in the early 20th century. The name "Pangaea" comes from the Greek word for "all lands." The theory of Pangaea has been supported by various lines of evidence, such as the matching shapes of continents and the distribution of fossils and rocks.
