Which continents made up laurasia?
north america and south america
europe, antarctica, and south america
north america, europe, and western asia
africa, south america, and eastern asia

The correct answer is - North America, Europe, and western Asia.

Laurasia was a massive continent located in the Northern Hemisphere. This continent was a result of the early breakup of the super continent Pangaea that initially split into two large land masses.

As the geologic process were continuing to break up the land masses, Laurasia was not immune to it, so it too started to break up. From Laurasia emerged the continents that nowadays are known as North America and Eurasia (Europe and Asia), but in the future there's a very high chance that these land masses will unite once more.
