By the end of the Cretaceous period, the continents were separating into land masses that look like our modern-day continents. An Austrian geologist stated that there had been once a land bridge connecting South America, Africa, India, Australia, and Antarctica. He named this land mass Gondwanaland. For how Pangea looked, it is better shown through a picture, than through words. So, what is happening now with the continents. As we speak, the continents are moving, they are always moving, how they move so slowly that you cant tell. Some of the continents move merely 1.5 inches a year, while the others move with lightning speed of 2.5 inches per year. It's about as fast as your fingernails grow.
