Pangea supercontinent from space‚ as it may have looked 300 million years ago. The Earth is a little over 4.5 billion years old‚ its oldest materials being 4.3 billion-year-old zircon crystals. Its earliest times were geologically violent‚ and it suffered constant bombardment from meteorites. When this ended‚ the Earth cooled and its surface solidified to a crust - the first solid rocks. There were no continents as yet‚ just a global ocean peppered with small islands. Erosion‚ sedimentation and

Shifting of Pangea Have you ever noticed that a map of the world looks like a puzzle and the continents look like the pieces that would fit together to complete the puzzle. In 1912‚ Alfred Wegener‚ a German scientist and an adventurer‚ came up with a theory that the continents had once been part of a "supercontinent". Wegener proposed that‚ over 200 million years‚ what he called Pangea had separated and became individual pieces. Pangea means "all lands" in Greek‚ and that is what Pangea was‚ a

Antarctica is a frozen land‚ so cold and icy that no trees can grow there. Yet scientists have discovered fossils (remains preserved in rock) of ancient trees in Antarctica. What do you think this means? That Antarctica was once a part of the

Life in the Triassic Period Just about everyone has heard of the age of dinosaurs and the Jurassic period but not many people know of the time before when animals‚ dinosaurs‚ and plants were just starting to flourish. The time before dinosaurs and animals was called The Triassic period which was at the beginning of the Mesozoic era which was approximately 251 million years ago and went on for about 50 million years. The Triassic period has three sections within which are called Early Triassic 251

modern day plants and animals. Through a process of speciation‚ the movement of the continents has had a generous role throughout evolution‚ effecting and distributing flora and fauna. The Earth’s continents were once one‚ a large supercontinent called Pangea that later separated into two smaller ones known as Gondwana and Laurasia. The separation and collision of continents has not only created some of the valleys and mountain ranges which are significant landmarks on the Earth’s surface‚ but it has also

In the 1800s‚ evolutionists stated they believe that Pangea split apart 95 million years ago. The Bible‚ written before the 1800s‚ found the earth was divided. When Columbus sailed to North America in 1492‚ he found people and animals. Evolutionists didn’t come up with the idea of Pangea until over 300 years later. So‚ the Bible described an event before its discovery (www.saysthelord.wordpress.com )!” In conclusion

The Continental drift was the process in which the Earth’s land surfaces ( at the time known as the pangea) started slowly breaking apart and drifting away. This has continued until the continents were in the places we know them to be today. This drift has caused the formation of separate oceans instead of one huge one. This drift still continues today. Volcanoes affected the origins of the sea by pouring huge amounts of steam into the atmosphere. This would result in the process

Will the Atlantic Ocean ever be bigger than the Pacific Ocean? The earth first started off as one huge continent called Pangea. Pangea was surrounded by one giant body of water. Over the course of millions and millions of years‚ Pangea began to break off and separate. After millions of years of movement‚ that is why the earth has the formation that it currently has‚ with seven large continents. With an area of 41‚105‚000 square miles‚ the Atlantic Ocean is currently just a little over half the

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
