Theory of Continental Drift
If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? Well, this claim was made in the 90’s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930.
Wegener’s theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Over time, the landmass broke and drifted away and is still drifting to this day. In his proposal, he stated that the super content, which he named Pangaea, meaning ‘’all earth” once existed. The supercontinent was surrounded by water bodies, mainly oceans, and seas.
