According to the text, what was a significant environmental consequence of the formation of the supercontinent Pangaea approximately 250 million years ago?

  • A: Ocean basins became shallower, leading to the expansion of coastal marine habitats.
  • B: Pangaea's interior became warmer and wetter, fostering diverse new ecosystems.
  • C: Ocean basins became deeper, resulting in the drainage of shallow coastal seas.
  • D: The overall climate became more moderate globally, reducing extreme weather events.

Explanation

The text states, 'Ocean basins became deeper, which drained shallow coastal seas' due to Pangaea's formation. It also notes that 'Pangaea's interior was cold and dry,' contradicting the idea of a warmer, wetter, or more moderate climate.
