what happened to the giant landmass that wegener described?\n\n- the pieces remained the same shape over…

Brief Explanations:

Alfred Wegener proposed the theory of continental drift in the early 20th century. He hypothesized that all of Earth's continents were once joined together in a single supercontinent called Pangea. According to his theory, this giant landmass began to break apart approximately 200 million years ago. The resulting continental fragments then slowly drifted across the Earth's surface over millions of years to reach their current positions. This process explains the jigsaw-like fit of the continents and the distribution of similar fossils and rock formations across different oceans.

Answer:

The pieces broke apart and drifted away from one another over time.
