What are laurasia and Gondwanaland?

Answer 1

Then about 200 million years ago the land began to drift apart. It broke into two pieces, and scientists have called the continent in the north Laurasia and the continent in the south Gondwanaland. Gondwanaland included what we know as Antarctica, which was joined to South America, Africa, India, and Australia.

The two large continents continued to break apart into the smaller continents that exist today. Scientists call this movement 'continental drift'
