Plate Tectonics‚ Earthquakes‚ and Volcanoes Renee Kuraly 1. There are 13 tectonic plates. (several smaller ones) 2. Evidence for continental drift includes: coastline fit‚ alignment of mountain ranges‚ similar rock sequences‚ fossils‚ modern fauna‚ and ancient climates. 3. We know plate boundaries exist because their defined by earthquake data and the depths of earthquakes show what type of boundary they are. 4. Divergent Boundary- places where plates are moving apart. Convergent Boundary-

points in this report revolve around tectonic plate subduction‚ uplift around the Denali fault‚ and the rock composition of the mountain. The combination of these three forces are integral reasons for why the mountain has been able to grow to its size and why it’s been able to maintain its height. To understand how subduction has affected Denali and the Alaska mountain range‚ you first need to understand how plate tectonics work. The theory of plate tectonics centers on the idea that the Earth’s

Evolution Is Just A Theory One of the main things that would be studied in biology is evolution. Although most people think that evolution is true and us humans have evolved from our formal ancestors. For the past year mankind has been thinking of one thing‚ which was evolution. The definition of mechanism is how evolution occurs over time. Evolution has been shown over the past billion years and humans have studied the creatures that have physically changed their bodies. The definition of evolution

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

proposal of continental drift that simply stated that there was once a supercontinent called Pangaea. He believed that 200 million years ago the continent began breaking into smaller continents which began the layout of where they lie now. Many people and geologists rejected Wegener?s idea especially the North American geologists due to most of his evidence to back his proposal up had been gathered from Southern continents. Evidence that Wegener had listed to support his theory of continental drift were

evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported with multiple pieces of evidence but his theory was never

June 2011 plate tectonics and associated hazards Comment on the extent to which the features shown in the image support the theory of plate tectonics. To begin with we can see that many of the landmasses appear as separated jigsaw pieces with their complementary shaped coastlines. One example of this is how the North Western coastline of Africa could quite easily ‘slot into’ the North Eastern Coastline of America. This suggests that in the history of the Earth‚ these two land masses were once connected

Adapted from an activity by Laurel Goodell February 2013 Introduction to Plate Tectonics via Google Earth (24 pts) B. Topographic Patterns Uncheck all of the layers and focus on topographic features of the earth. Topography of the earth ABOVE sea level Questions Answers 1. Are mountains randomly distributed on the continents‚ or do they tend to occur in particular patterns (clusters‚ linear chains‚ arcs‚ etc.)? Some appear in lines and others in arcs 1pt 2. Find Mt.

Plate tectonic theory is a widely excepted theory that the Earth’s lithosphere is made up of plates‚ both oceanic and continental‚ which slowly move due to convection currents in the mantle and the asthenosphere. However‚ it is very hard to be certain as we can’t see the structure of the Earth‚ so some people do not agree with it. This theory saw the introduction of what we know today to be tectonic plates. Tectonic plates occur where there is radioactive decay in the core and temperatures are extremely
