‘Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid.’ Discuss the extent to which you agree with this statement. (40 marks) Over the years proceeding the birth of the theory‚ increasingly convincing evidence has been gathered for proof of the theory of plate tectonics. In 1912‚ Alfred Wegner proposed the theory that continents are sat upon tectonic plates and that these plates are slowly drifting around the Earth (continental drift).

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-

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental

‘The hazards presented by volcanic and seismic events have the greatest impact on the world’s poorest people’ to what extent do you agree with this view? (40 marks) Volcanic and sesmin events and activities can take place all over the world and therefore both more economically developed countries (MEDCs) and less economically develop countries (LEDCs) can be affected. In the last 30 years there have been masses of examples of where volcanic and seismis event have had an impact on both MEDCs and

This is a very important question that haunts us every day‚ because we don’t always know when they are coming and how bad they will be. I am Donte Lindsey and I am the director of Earth Preparedness of Los Angeles. With any type of danger the first thing you need to be prepared with is knowledge. Today we will discuss the hazards

development of the theory of plate tectonics from Continental Drift to the present The theory of continental drift first came to be in 1915 when Alfred Wegener first proposed his belief that 300 billion years ago there was one single supercontinent‚ Pangaea. At the time‚ most did not believe it was true as he had no proof or idea of how the masses of land would move. However‚ new evidence was put forward over time that fit with Wegener’s beliefs. The first key piece of evidence is the shape of each

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.

How Plate Tectonic Theory Explains Mountains Shadi Alostaz The Plate Tectonic Theory explain mountains because they form in oceans. Mountains primarily form at plate margins‚ or places where boundaries of plates meet at and interact (Nagel and Sawinski 1). The mountains form in oceans mostly because of the mid ocean ridges. The mid ocean ridges converge‚ creating underwater mountains. The mountains above ground are mostly caused‚ and responsible for convergent plate boundaries The Plate Tectonic

Would the world be the same if there weren’t plate tectonics? The answer is no‚ because that is how the oceans‚ land‚ and many more things were created. There would be no rocks or plate boundaries. Every living thing on earth would have to adapt to these types of things‚ if there even was living things on earth. The different types of rocks like igneous‚ sedimentary‚ and metamorphic have to go through a process to become that type of rock. Igneous is formed when magma is cooled and
