the landmass of pangaea split into separate continents over time.

pangaea was surrounded by the waters of the ocean.
the coastline of pangaea stayed consistent over time.

Explanation:

• Pangaea is a supercontinent that existed about 300 million years ago. According to the theory of continental drift, it gradually split into the continents we know today.
• It was surrounded by a single global ocean called Panthalassa.
• Christopher Columbus discovered America, not Pangaea. And the coastline of Pangaea changed as it split, so the statement "The coastline of Pangaea stayed consistent over time" is wrong.

Answer:

• The landmass of Pangaea split into separate continents over time.
• Pangaea was surrounded by the waters of the ocean.
