Geographic Evidence To Support The Theory Of Continental Drift Essay

1. What is continental drift? Continental drift is the gradual movement of the continents across the earth’s surface through geological time. The theory of plate tectonics, which use to be called continental drift, is described as the movement of the continents and sea floor across the surface of the Earth. The theory explains many odd facts about Earth’s geology, such as the present arrangement of landmasses which have stated that the Earth’s crust slowly drifts atop a liquid core. 2. What was

Continental drift is the theory that Earth’s continents have moved around the Earth’s surface throughout geologic time to get to where they are at today. The theory of continental drift has been a controversy, but findings have made the theory more supportive. This theory at the time changed the way on how we viewed the origin of the continents. It was a big discovery but many were reluctant to accept the theory. The man that came up with the theory of Continental Drift was Alfred Wegener. Alfred

10/14/2015 Mr. Ramphal Streetsville Secondary School U3A5 - Evidence of Moving Continents The Movement of Continents Introduction How do we know that continents can move across vast distances over a long enough period of time? It is very hard to imagine what amounts to 150 million kilometers squared of land that we have on the earth moving such an incredible distance. This was the main idea opposing the Continental Shift theory: there were no known forces strong enough to move entire continents

Evolutionary Concepts Activity 6 1. Evolutionary theory describes how populations change over time due to changes in the gene pool. There are several mechanisms that can change a gene pool and allow evolution to occur. Natural selection, mutation, gene flow and genetic drift are some of the driving forces behind evolutionary change. Natural selection and genetic drift are the mechanisms that decrease genetic variation, whereas gene flow and mutation are the driving mechanism to increase genetic

Wegener drew to show the distribution of continents 300 million years ago. His theory of continental drift was met with skepticism in the scientific community. 1. Describe three forms of evidence Wegener used to support his ideas of continental drift. • Continental Margins (Visually land masses fit together like a puzzle) • Rock layers (similarity on the coast lines as well in a different continent • Fossil evidence (How some animals were identical

Continental Drift and Plate Tectonics Theory (Part 1a) Introduction: The Beginning of the “Continental Drift Theory” In the middle of the eighteenth century, James Hutton proposed a theory, uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg, 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham

Antarctica-Australian landmasses and drifted northward until it collided with Eurasia (Europe and Asia). This collision created a continental block which caused a separation of the Antarctica-Australia landmass and caused the individual landmasses to shift in opposite directions (Whitmore 1981). This separation formed an underwater ocean ridge, which caused Australia to drift northwestward. Around 15 million years ago, Australia converged with Asia, uniting the diverse flora and fauna of both regions

Phylogeography is a field of study that implements biogeography and genetics to understand the geographic distribution of a species. It is concerned with historical principles and processes that influence evolution and speciation. The tiger is an evolutionary wonder; it is a prime example of the responsiveness that some species have to changing climatic conditions. The tiger once had the largest geographic distribution of all cat species; subspecies adaptations allowed them to live in a large range
