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…

The movie “Friday Night Lights” is a movie where it is entertaining, fun and it has many aspects to it where you can learn about life through sports. The movie takes place mainly down in Odessa,Texas in 1988 where a local high school known as the Permian Panthers has state championship goals and expectations going into the season knowing the roster and coaching that they currently have. A few years prior, they had taken the big award down there of winning the state championship in Texas. Their…

Sharks don’t fossilize well because they’re from the class of chondrichthyes meaning their skeletons are made of cartilage, a flexible connective tissue. This is one of the reasons why there is a disagreement over when the first shark first existed. However, shark teeth do fossilize well and sharks produce thousands of teeth in a lifetime. The oldest shark teeth date back to the Devonian Period about 400 million years ago and were found in Europe. Shark scales also fossilize well.…

The changes vary across the Arctic; the largest decreases occur in maritime regions of the Arctic (Alaska, northern Scandinavia, and the Pacific coast region of Russia) [8]. Climate model projections indicate decreases in the duration of snow cover of 10 to 20% over most of the Arctic by 2050 and Scandinavia will experience the most loss (around 30 to 40%) [2]. 2.4 Temperature Average Arctic temperatures have increased at almost twice the global average rate in the past 100 years according to…

terrestrial environment was dominated by dinosaurs. Dinosaurs arose from fully bipedal ancestors, who is believed to have been a carnivore or omnivore (Langer, Ezcurra, Bittencourt & Novas, 2010). These agile terrestrial archosaurs lived during the Late Permian and Early Triassic and had already developed key changes in the hips and ankles that set the stage for the increase in body size that is seen in dinosaurs (Pough, Janis & Heiser, 2013). This included an alteration in the hip that allowed…

INTRODUCTION The human population on Earth has been growing at an alarming rate bringing with it an ever growing need for food, energy and land use, amongst many others. At the same time, the list of animal species recorded as being extinct or on the verge of being extinct gets longer and longer. Is this phenomenon coincidence or are these two occurrences directly link to each other? This research task aims to investigate if there is reliable proof that human population growth and species…

The Devonian mass extinction suggesting that warm water marine species were the most severely affected. It was also argue that the extinction of the Devonian was triggered by another glaciation event. The third biological crisis was the Permian-Triassic extinction which took place 251 million years ago and which was the worst mass extinction of the Earth. Scientists argue that 95% of all species, containing 84% of marine genera, 53% of marine families, and around 70% of land species as plants…
