Question

define the term Pangaea and panthalassa
​

Answer 1

Answer:

Pangaea or Pangea is the name given to the supercontinent that existed during the Paleozoic and Mesozoic eras, before the process of plate tectonics separated each of the component continents into their current configuration. The name was coined by Alfred Wegener, chief proponent of Continental Drift in 1915.

Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), was the superocean that surrounded the supercontinent Pangaea. During the Paleozoic–Mesozoic transition c. 250 Ma it occupied almost 70% of Earth's surface.

Pangaea is a massive supercontinent which existed a 300 million years ago when the seven continents where not formed.

➲ Panthalassa :-

Panthalassa, also known as the Panthalassic Ocean, was the vast global  ocean which surrounded the supercontinent Pangaea.

More info :-

✦ According to the mordern theory of plate techtonics ,The pangaea was formed when the earth's outer shell is broken up into several plates that slide over Earth's rocky shell, the mantle.

✦ Gondwana Land - Africa, South America, Antarctica, India and Australia) first split from Laurasia (Eurasia and North America).

✦ Panthalassa included the Pacific Ocean to the west and north and the Tethys Ocean to the southeast. It became the Pacific Ocean, following the closing of the Tethys basin and the breakup of Pangaea, which created the Atlantic, Arctic, and Indian Ocean basins.

✦ The Panthalassic is often called the Paleo-Pacific because the Pacific Ocean developed from it in the Mesozoic to the present.
