Gondwana

credit to a number of past authors with alike ideas: Franklin Coxworthy (between 1848 and 1890), Roberto Mantovani (between 1889 and 1909), William Henry Pickering and Frank Bursley Taylor . Eduard Suess had stated the theory of a supercontinent Gondwana in 1885 and the Tethys Ocean in 1893. John Perry wrote a paper in 1895 saying that the inside of Earth was fluid, and disagreeing with Lord Kelvin on the age of the earth. After closely observing a globe it shows that the continents come…

Wegener’s hypothesis of Continental Drift Alfred Wegener believed all Earth’s continents were once joined together but gradually moved apart for millions of years by cracking and dividing due to slow currents of magna beneath it. 2. Cut out the attached Gondwana Jigsaw along the dotted lines. Fit the continents together and glue them in position. Hint, refer to other sheets for map. 3. Describe the evidence for Continental drift. All the continents fit together much like puzzle pieces that…

What are dinosaurs? Dinosaurs are enormously large reptiles (cold blooded animal) that lived during the Mesozoic era which is about 230 million years ago. Contrary to the general believe that all dinosaurs were cold blooded animals thought to be sluggish, there were dinosaurs who were warm blooded animals that shared more similar features with aves (birds) of these days than with reptiles, example of which is the velociraptors which belong to the genera Theropods. Some of these dinosaurs are…

affected biodiversity (7). Zhang et al. (7) pointed out that the formation of mountains from clashing continents caused a shift in weather patterns which resulted in increased nutrients. In his paper he mentioned specifically the formation of the trans-Gondwana mountain range that resulted in an increase in phosphorus from a change in weather patterns. Pages et al. (1) discovered that within these tectonic plate shifts were clues that could help piece together what changes happened that led to…

It was on the unforgettable day of March 11, 2011 that nineteen thousand people perished in a catastrophic event known as the Japanese tsunami. The assertion made by Aaron Kong, "It is human action and not nature that should be blamed for the destruction of our world and the suffering and death of so many people everywhere," is partly correct in the sense that humans are indeed responsible for the misery of many people. However, humans are not completely to blame because nature also plays a…

magmatic, and metamorphic activity of Neoproterozoic to earliest Paleozoic age throughout the Gondwanaland and in many parts of Laurasia. East Africa orogen (EAO) was formed by the closuring of Mozambique Ocean during the collision of East and West Gondwana (Stern, 1994; Kröner and Stern, 2005; Fritz et al., 2013). It represents the greatest collision zone which extends from southern Israel in the north to Madagascar to the south. The Neoproterozoic basement of Ethiopia is found at the…

Citizen journalism is defined as public, participatory or street journalism. Citizen journalism is based upon public citizens playing an active role on collecting data and be intermittent on social media. With the increasing development of social media, citizens have been posting, tweeting and reporting on-the-spot news. At present, most citizens have been practicing citizen journalism effectively. However, with that, there might be a few risks and opportunities that come when practicing citizen…

Around 380 million years ago, during the Devonian Period, North America and Baltica collided. This collision created another mountain range located in the same place where the Grenville Mountains and Taconic Mountains were formed. The Acadian Orogeny happened on the northeastern side of North America. Like TIA and the Grenville Belt, there was another land piece between Proto-North America and Baltica. This land piece was called Avalon. Avalon was believed to have broke apart from…

Natural selection is a key mechanism of the evolutionary process and relates to the occurrence of certain traits within a population and they way in which these traits affect the survival and reproductive success of an organism. Organisms need to be able to adapt to their environment in order to survive and reproduce. Any advantageous traits that occur within a population increase an individual’s chance of survival, thus resulting in the organism producing more offspring than those who have not…

Neotectonics in Australia. Abstract The cratons of the world that are located at a distance from plate boundaries are considered to be stable tectonically, but in real sense, they are subjected to regular disturbance that are less persistence and also of lesser magnitude than those that lies near plate boundaries, Nonetheless their manifestation can be seen in landscape. Neotectonics are post Miocene tectonic deformation on the earth surface. Its evidence takes expression in form of recent…
