How Did the Ancient Land Blob Called Gondwana Become Today's Southern Continents?
Lauren Bogle bomb here sometimes. Good Science Science can happen just by looking at a map of the world and letting your mind wander for instance observe how Africa and South America seemed to have been very recently cuddled together even though there are currently a couple of thousand miles of ocean between them similarly Madagascar fits perfectly into a little nick in the eastern edge of Africa and the Middle East seems seems to be pulling away from the top of Africa like a corner being pulled off of a hot cookie with a reasonably good representation of the shape and arrangement of the world's continents in front of them. Anyone could easily assess the earth's land masses have definitely been speaking around the name for the southern landmass that once was is Gondwanaland and also known as Gondwana but it wasn't just the shape of the continents that clued researchers into its former existence. They've also looked at similarities. Among plants and animals that live across the modern separate continents from those clues. Gondwana was an idea long before anybody figured out how or why. It worked the secret of course being plate. tectonics and idea that didn't really start gaining steam. Until the mid twentieth century but a nineteenth century Austrian geologist named Edward Seuss put a name to the concept of the supercontinent in his book. The face of the earth the first volume of which was published in eighteen eighty. Three SEUSS didn't come up with many completely novel ideas ideas. But he did a great job of synthesizing. A bunch of the research of the day to conclude that the southern continents and landmasses we now know as South America Africa Arabia India via Sri Lanka and Madagascar had at one point in time been connected because one well just look at them and two. They contained the same rocks and the same fossil's from an extinct feathery leafed tree called gloss of terrace Austria and in Arctic. Oh would be added theory. Thirty years later Gondwana on what was named for a densely forested region of central India where the first fossil evidence of the supercontinent was found in the nineteenth century. WanNa is a word for forest in Sanskrit and the guns are tribe that European explorers. I found living in the region. Even though we now know a lot about the mechanism by which Gondwana China was formed. It's extremely complicated and still being investigated. There's at least one. Peer Reviewed Scientific Journal devoted entirely to the study of the supercontinent. It's it's called appropriately Gondwana research however. There are a few things that we're pretty certain of I got Wada wasn't built in a day. The the making of Gondwana was a long process. Most likely through three major mountain building events driven by the movement of Earth's tectonic plates we spoke spoke via email with Joseph Merit professor in the Department of Geological Sciences. At the University of Florida he explained during the interval from about six hundred fifty to five hundred in fifty million years ago. Various pieces of Africa and South America collided along an ancient mountain chain called the Brazilian belt slightly older but overlapping with the Brazilian. Oh seven seven hundred and fifty to six hundred and fifty million years. AGO is the east African Oregon or Mozambique Belt that resulted from the collision between East Africa and Madagascar India Tree Lanka and parts of East Antarctica. The final collision was along the Kouanga Oregon between all those assembled pieces and the rest of Antarctica and Australia between five five hundred eighty and five hundred and thirty million years ago so it was a couple hundred million years of extremely slow continental car wrecks the created this Beta Ada version of Gondwana. But it wasn't done yet later about three hundred million years ago other landmasses join forces with it to form the giant ball of land. We now no no as Panja. But one continent rule them all couldn't last and sometime between two hundred eighty and two hundred million years ago. Hingis started started disintegrating as magma began pushing up from beneath the mega supercontinent creating rifts in the land that would later become seafloor as Penn.. Jia cracked the top part was pushed to the north creating the continent Laura Asia and Gondwana headed south back when Gondwana was just a baby supercontinent between five hundred and fifty and four hundred eighty five million years ago it hosted some of the very first complex life forms like trial abides bracket pods but since it continued to exist I didn't the drastic period lots of plant and animal. Evolution went down there merit said Gondwana contains evidence for evolutionary changes in the very first complex complex animals. The very first fish amphibians and reptiles the most famous fossils are the gun doina flora such as the loss of terrace fern a freshwater reptile called. Messo Soroush Soroush in a land. Reptile called Lyster Soroush Gondwana existed as a single landmass for more than three hundred million years because of its humongous assize by covered an area of one hundred billion square kilometers or about thirty nine billion square miles and because the continents moved a lot during that time Gondwana experienced many different climates said during the Cambridge. When Gondwana I formed the earth and Gondwana were in a greenhouse state in the late order vision? Four four hundred fifty million years ago gun was moving over. The South Pole and the climate was very cold. Gondwana continued to move through variety of latitudes and depending on where you are located hated. The climate might have been quite warm or more temperate. The continent was so large. That one part of Gondwana might be located at the quarter while another might be located at the poll. It's true it would have been cool to see Gondwana in its prime and although you won't personally get to see its victorious return. That doesn't mean that it's not possible. Possible the continents are always moving and scientists have a lot of ideas about what our next supercontinent is going to look like.
