Answer:
Continents were once one landmass and have drifted apart.
Explanation:
Wegener's continental drift theory is based on the idea that the seven continents were once fused together as one super continent before eventually drifting apart under tectonic movement. This idea has received support from how continents on the map has been seen to be close fits and the finding of fossil materials across oceans from where they are currently found.
Answer:
Continents used to be one landmass, but they have since moved apart. The continental drift theory was proposed by Alfred Wegener. According to his hypothesis, the planet began as a single compressed protocontinent that eventually drifted apart to form the continents we see today.
Explanation:
Wegener studied a global map and saw how the continents resembled a jigsaw puzzle. South America and Africa appeared to be the first to join forces. Similar fossils were discovered in the areas where the opposing sides would meet. Also observed were similar flora and animals. As a result, he hypothesised that the continents had migrated apart. So far, more evidence has been discovered to back up his theory.
