1. Introduction The Brent field is an oil field located in the East Shetland Basin. This oil field was the first discovery in the northern part of the North Sea. It is located 186 kilometres north-east of Lerwick, Shetland Islands, Scotland at the water depth of 140 metres (460ft). (Figure 1) The field lies entirely within United Kingdom (UK) licence Block 211/29 at latitude 61°N and longitude 2°E. The Brent field is one of the biggest hydrocarbon accumulations in the United Kingdom area.…

Five extinctions of Earth and Who will be Next? The Earth we live on now is drastically different from how it was millions of years ago. The Earth has gone through many changes and events though time. There are five major events in history that have changed the world. Without these five mass extinctions who knows what Earth would have looked like, and if humans would even be alive. In the ordovician period 439 million years ago there was a mass extinction that wiped out 89% of life on Earth.…

tonnes of material get eroded, which is about 1 to 2 meters of erosion occurs every year. Because of this rapid erosion, about 30 villages have been sank into the sea since the Roman times. This is due to the fact that the Holderness Coast is made of Cretaceous Chelk, and is covered by bolder cray that deposited from the last gracial retreat about 10000 years ago. Also, the Holderness coast is exposed to powerful waves: hydraulic action and abrasion are often seen on the coast. In addition, the…

Evolutionists use the geological column as a means of supporting their theory of evolution. The geological column is the theory of a sequence of rocks extending through time from the oldest at the bottom to the youngest mud, dirt and sand deposited on the surface. In many locations around the world, fossils have been discovered that run through many layers of rock. These fossils are known as polystrate fossils. This occurs when a fossil is deposited quickly and through a very large event, such…

According to the theory of natural selection, the Sauropods 's long neck is an adaptation for browsing high vegetations. Also, their long neck was also adapted for a large feeding envelope because they need to hold their food while moving from one tree to another. Their huge body is used to store food too. Sauropods ' bodies are big because they have a large digestive tract to store food inside until they get to the next vegetation area as well. The sauropods ' bodies were also used to scare…

feathered dinosaurs called Raptors. Raptors were feathered Theropods that varied in size from no bigger than a large chicken, to exceeding the height of a full grown man. The time the Raptors lived mainly centered around 65-90 million years ago in the Cretaceous era. A Raptors diet mainly depended on its size. If the raptor is small it goes after small prey or insects unless they have a big enough group to take on larger prey. In some cases like Velociraptor, if there wasn’t enough food around…

horizontal forces are compressing the crust. It struck Jones that a sudden drop in gravitational potential energy might have given the crust enough of a jolt to create the Laramide ranges. His scenario goes like this: 141 million years ago, during the Cretaceous Period, western North America from the Arctic to the Gulf of Mexico was covered by a shallow sea that some geologists have dubbed the Western Interior Seaway. Dead marine organisms rained down on the seafloor, forming thick sediments…

floor, rose upwards about 75-100 kilometers and melted rocks in its path, creating the volcanic activity that gave rise to rock formations away from the subduction zone. The time at which all these process are dated to have taken place is during the Cretaceous…

species are quickly disappearing, Kolbert admits she is not only looking for a solution to the problem, but knowledge on the topic as well. With the time bomb slowly ticking away, one might allude this ‘mass extinction’ upcoming to the end of the cretaceous period when the dinosaurs took their last breath before being extinguished by meteors. This similarity is the world’s most recognizable extinction, even though there were four more throughout history. Today’s problem is identified as a ‘mass…

The Six Great Extinctions Extinction is just another word used for the dying off of one species or of many species. Since the beginning of time there have been five mass extinction and then some smaller extinctions. Either big or small, they play a huge role in the evolution of the species around us. Whether they were a common ancestor, or a close relative to an organism, they still helped the organisms we know today evolve and adapt to the environment that we now share. During the extinction…
