Gondwana Essays

Planet Earth has experience four eras that include eleven periods and six mass extinctions throughout evolution. The Evolving Planet exhibit at the Field Museum in Chicago, IL describes the evolution of Earth in great detail. The evolution of Earth starts in the Precambrian period and continues to the Cenozoic era, which is still continuing today. Evolution is the idea that living species are descendants of ancestral species that existed from earlier forms of life. All the organisms, rocks, or other

and almost all landmasses on earth that we know today. Before the separation of every particular continent, Pangea had split into two different super continents because of cracking on the earth’s crust. One of those supercontinents was called Gondwana. Gondwana was composed of South America, Arica, Australia, Antarctica and India, which are now separate individual continents. This supercontinent was in existence around 180 million year ago and was placed around the middle of the earth. This helped

Continental Drift The world has not always looked how it does today. Gondwana, originally known as 'Gondwanaland', was an ancient southern supercontinent that formed as the result of the division of a much larger supercontinent known as Pangaea. Pangaea existed around 500 million years ago until 150 to 300 million years ago when it broke apart to form the super continents Gondwana and Laurasia. Gondwana was composed of South America, Africa, Madagascar, India, Australia, Antarctica, the Arabian

movement of the tectonic plates resulted in Pangaea being split into two smaller land masses. These two smaller land masses were identified as Gondwana and Laurasia. The splitting of Gondwana and Laurasia occurred around 230-280 million years ago. Gondwana or ‘Gondwanaland’ was a primeval supercontinent and was once the southern land mass of Pangaea. Gondwana consisted of not only continents but countries too. Today they are known as South America, Africa, Madagascar, India, Australia, New Zealand

years ago Pangea broke apart into two pieces, Laurasia and Gondwana. Gondwana consisted of the continents we now recognise as Africa, South America, Australia, Antarctica, the Indian subcontinent and the Arabian Peninsula. Due to the size and the positioning of Gondwana, the climate varied from very hot to very cold. Theoretically, Gondwana would have looked similarly to Antarctica how it is today, nevertheless, during the hotter climate Gondwana would have been covered in lush rainforest much like a

3 to 443.7 million years ago. The Ordovician period is mostly known its various marine invertebrates. The climate during this period seemed to be mostly cold. At the time most of the lands were combined into one super continent, which was called Gondwana (The Ordovician Period). The third geological period during the Paleozoic Era was the Silurian period. This period took place roughly around 443.7 to 416 million years ago. The Silurian period was when we started finding clear evidence of life

3. The Paleozoic Era was from 542 million years ago to 251 million years ago; at this time big changes began to happen on Earth. The era began with the disintegration of a supercontinent and the creation of another. Plants began to grow all over the place. Also at this time the first vertebrate animals conquered the land. Also Paleozoic appeared with the Cambrian Period, 53 million years is when life started to burst on Earth. The Cambrian period again gave way to the beginning of arthropods

Alexander du Toit, picked up the research that Wegener started and gathered more evidence to prove continental drift. His developments included looking at the glacial deposits in the Gondwana and coal deposits of the same age from the Northern Hemisphere and found they differed because of the climate regions. He took the Gondwana land masses (South America, Africa, India, Australia, and Antarctica) and moved them to the South Pole and placed the Northern lands called Laurasia (North

evolution by observing different species behaviors, characteristics and mutations in their natural habitat and documented their discoveries. This theory states that; “All living things evolve by adapting to their environment.” On the supercontinent of Gondwana, the species roamed free, all individuals of the species were alike. When continental drift separated the landmass into two the species were divided between them. Each subgroup of individuals adapted so differently to each other due to their different

mostly found growing in the water. First, many things contributed to the environment the Ordovician Period had. “Areas north of the tropics was almost entirely ocean; most of the world’s land was assembled into the southern supercontinent Gondwana. Gondwana shifted towards the South Pole and much of it was inundated underwater throughout the

• The Rodinia broke apart into two different continents. • The mass that would eventually become modern Africa, Australia, South America, Antarctica and parts of Asia was called Gondwana, and it was located near the South Pole. • Laurentia would break up to become North America and much of Europe and it was located closer to the equator. Climate • The Earth was generally cold during the early Cambrian. • There were likely polar

The world is forever evolving, never remaining permanent. Land that once rose above the sea years ago is slowly sinking due to rising sea levels and global warming, animals evolving and having to adapt to new environments after the earth’s crust parted due to continental drift creating new islands and continents. The proof for the theory of evolution is embedded in the crusts of the earth of today, telling the story of the geography of genetics. What is evolution? Evolution is the gradual change

Through working at ‘Rossmoyne Senior High School’ and ‘Curtin University’ I have learnt certain IT skills, such as managing networks, support skills, and to how to communicate well in a team. However, I also work very well independently. From studying units such as ‘Screen Practice’, ‘TV Studio Workshop’, ‘Advertising and Music Video Production’, ‘Corporate Documentary Screenwriting’, ‘Corporate Documentary Production’, Transmedia and Multiplatform creation’ ‘Broadcast production’ and ‘Introduction

It’s 5 o’clock in the afternoon. The 1989 World Series is about to start. The TV goes to static. Houses come crashing down. Dust is everywhere around the wreckage. Smoke is flooding the streets. Downed fire hydrants spray into what 's left of a parking garage. All of this damage was caused by an earthquake. Earthquakes affect not only the Earth, but people and the property on it. To start off, Earth’s continents slide on a liquid molten mantle which cause them to collide and separate

The Amazon River Basin is home to the largest rainforest in south America and the earth. The basin is about 5.5 million km² in size which shows it’s massive. The forest spreads over all these South American countries Brazil, Peru, Ecuador, Colombia, Venezuela, Guyana and Suriname. The amazon is made of up lots of ecosystems and vegetation types including many forests like seasonal and flooded forests and even savannas. The amazon river is the world’s largest river of discharge but it is the second

unique physical, cultural environment and human environments. Australia’s unique physical environment can be seen through the biologically diverse flora and fauna. Australia’s climate diversity, geological isolation and size during the breakup of Gondwana

Already there were evolved organisms spread out across the vast land. During the breakup of Pangaea, resulted two supercontinents, Laurasia and Gondwana. These two split, moved, and so on. This resulted in many changes of environment, which caused animals to adapt and evolve to the isolated environment of islands. For example, Australia had been isolated by water resulting in the mammals not having

extinct. When megafauna were alive the climate was changing. Australia’s climate was cooler, because Australia was attached to Antarctica. Evidence is shown in Hallet Cove because rocks had glacier scratches. A rise in temperature occurred when Gondwana broke up (fig 2), all the animals had to change their ways of living because the climate changed from cold-dry to warm-dry. The sudden change in

Cenozoic The Quaternary (Pleistocene to Recent) The Quaternary period was shaped by some many events. However, the Ear was characterized by interglacial arrangements. Three periods marked the Cenozoic Era; Paleogene, Quaternary, and Neogene. However, the Cenozoic era was characterized by climatic changes. This accounts for the rich agricultural deposits in Ohio. As a result, the land is adequate for landfill exploration. Consequently, Ohio soil contains huge amounts of fossils, silt, clay sand, and

were coming together. The surveys written by Friedman and Sallan and Young discussed the role that the shifting of the continents had on the placoderms. This change in the orientation of the continents, specifically the movement of Euamerica and Gondwana closer together, started to close the large ocean that separated the two continents. It is safe to assume that this change in the orientation of the continents would have meant trouble for the organisms that lived in the affected area. Throughout
