1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

that a God could not have made this happen. “And God said‚ Let the waters under the heavens be gathered together unto one place‚ and let the continents drift apart by plate tectonics. He decreed sea floor spreading would create zones of emergence‚ and He caused subduction zones to build mountains and cause earthquakes” (Shermer‚

The Juan De Fuca tectonic plate is found on the west coast of North America. It is next to the North American plate‚ and according to America’s Tectonics‚ the Juan de Fuca plate is getting subducted under it. This plate is made of oceanic crust‚ but it is also basaltic in some areas. It was named after the pilot and sailor‚ Juan de Fuca‚ an explorer from Europe in the 1600s. The Juan de Fuca plate has a divergent boundary in the Juan de Fuca ridge. New material is made by the Juan de Fuca ridge

I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper‚ I will discus the history of earthquakes‚ the kinds and locations of earthquakes‚ earthquake effects‚ intensity scales‚ prediction‚ and my own predictions. An earthquake can be defined as vibrations produced in the earth’s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations

Discuss the evidence for tectonic plate movement There has been a variety of different evidence for tectonic plate movement but the main evidence was Wegener’s theory which was based on a variety of different evidence from several sciences. Alfred Lothar Weneger was a German polar researcher‚ geophysicist and meteorologist‚ he first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. In 1912‚ he proposed his explanation – the

explosive eruptions and pose a great many problems for people and animals nearby1. This is in contrast to the volcanoes found in Hawaii which have slow flowing lava eruptions and few if any massive explosions. Mount St. Helens is formed by a subduction zone where the Juan de Fuca Plate plunges beneath the North American Plate causing the uplifting of the Cascade Mountains. The last eruption took place on May 18‚ 1980 and had such a force that was compared to 500 Hiroshima atomic bombs going off at

The definition of rivalry has now reached the range of sports. To beat your rival is the greatest feeling in sports‚ because it gives the victor this type of swagger and bragging rights for the team/city that carries throughout the rest of the season. But it doesn’t just matter about the players and the results‚ but as a franchise of the Portland Timbers it can reach a new level with the adding of the fans‚ the stadium and the environment of the city on game day. The Portland Timbers are a better

they are pulling apart from each other they are called Divergent Boundaries. If they are bumping or sideswiping each other they are transform boundaries. Convergent boundaries occur when two plates slide towards each other. They can also create subduction zones which means that one plates moved under the other. They may also create an orogenic belt which refers to two
