Assess the strength of the relationship between tectonic processes and major landforms on the earth’s surface. Tectonic processes have been responsible for the major landforms across the Earth’s surface. These processes are controlled by the convection currents rising from the Earth’s mantle. Firstly‚ one place where tectonic activity occurs is at oceanic to oceanic constructive plate boundaries. Here two plates diverge or move away from each other‚ pushed apart by huge convection currents

To answer the following question: Relate the generation of all three rock types (igneous‚ sedimentary‚ and metamorphic) to plate tectonics. I will start first‚ with igneous rocks and how does it relate to plate tectonics. Second‚ with sedimentary rocks and progressively keep on answering how all three types of rocks relate to plate tectonics. Will be giving as much information I learned from class. To assure‚ answer is fully answered. The igneous process begins when magma forms by melting at depth

Plate Tectonic Assignment 1. The Juan de Fuca and Cocos plates were once part of a much larger plate called the _________ plate. 2. How long ago was this plate the dominate plate? 3. What plate(s) are the remnants of this former plate? 4. What kind of plate boundary exists between the Juan de Fuca and the North American plate? 5. What kind of plate boundary exists between the Pacific plate and the North American plate? 6. What tectonic process is ongoing between Baja California and the North

Activity No. 2 Simulating Movement of Tectonic Plates Problem: How do tectonic plates move? What you need: -4 pieces of colored modeling clay -cardboard -newspaper What to do: 1.Flatten two pieces of modeling clay on the newspaper. 2.Cut the center of the clay strips and insert a cardboard on the part of the clay that was cut. 3.Push both ends of the clay strips.Observed what is formed. 4.Repeat step one in the other two pieces of modeling clay. 5.Slowly pull both

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

How does the theory of plate tectonics help to explain the world distribution of earthquake and volcanic zones? The Earth’s crust is made up of seven major plates and several smaller plates. These plates drift on top of the mantle. When two plates meet‚ they can either be constructive‚ destructive or conservative. At a conservative plate margin‚ one plate moves past another. As the plates are not smooth‚ great amounts of tension build up and earthquakes are made when the tension is released

In the early 1960s‚ the emergence of the theory of plate tectonics started a revolution in the earth sciences. Since then‚ scientists have verified and refined this theory‚ and now have a much better understanding of how our planet has been shaped by plate-tectonic processes. We now know that‚ directly or indirectly‚ plate tectonics influences nearly all geologic processes‚ past and present. Indeed‚ the notion that the entire Earth’s surface is continually shifting has profoundly changed the way

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
