Answer 2

The drifting of continents is known as Continental Drift and Tectonic plates are pieces of lithosphere that float on the asthenosphere.

• The concept of continental drift was first explained by a German scientist named Alfred Wegener.
• He came up with this concept because he noticed that the coast of western Africa and eastern South America appeared to him as puzzles pieces.
• According to Wegener, these puzzles pieces could have been joined as one piece of land but later got drifted apart due to calamities.
• Therefore, he theorized that all these lands or continents joined together as supercontinent or Pangea which was formed around 225 million year ago and later got drifted apart as single continents.
