people better comprehend why Wegner was not insane and how reliable his work is to this very day. Wegener was convinced that all of Earth’s continents were once part of an enormous‚ single landmass called Pangaea. To describe continental drift & pangea‚ Wegner used geology‚ biology‚ and ecology; even though he was initially trained as an astronomer. Pangaea existed about 240 million

Pangaea‚ Pangæa‚ or Pangea (pron.: /pænˈdʒiːə/ pan-JEE-ə;[1]) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras‚ forming about 300 million years ago.[2] It began to break apart around 200 million years ago.[3] The single global ocean which surrounded Pangaea is accordingly named Panthalassa. The name Pangaea is derived from Ancient Greek pan (πᾶν) meaning "entire"‚ and Gaia (Γαῖα) meaning "Earth". The name was coined during a 1927 symposium discussing Alfred Wegener’s

the rock cycle. The ideas and theories that make up plate tectonics have shown Earth’s dynamism. The position of plates on global maps didn’t always look similar to the maps shown today. 250 million years ago‚ there existed a super continent‚ Pangea‚ which contained all land masses on Earth. Before plate tectonics‚ people thought the plates were always in the same position; no one could explain how such a large mass could move. It split up some 200 million years ago but scientists recently accepted

story about 250 million years ago. During this time‚ all the earth’s land was a single super continent called Pangea‚ which was surrounded by a large ocean. Around 200 million years ago (also known as the Middle Permian Period)‚ an extensive sea stretched along the latitudinal area presently occupied by the Himalayas. This sea was named the Tethys. Around this period‚ the super continent Pangea began to gradually split into different land masses and move apart in different directions. As a result‚ rivers
