plate tectonics Click the link for more information. . Because the sides of a plate are either being created or destroyed, its size and shape are continually changing. Such active plate tectonics make studying global tectonic history, especially for the ocean plates, difficult for times greater than 200 million years ago. The continents, which are c.25 mi (40 km) thick, are embedded in some of the plates, and hence move as the plates move about on the earth's surface.

Plate Tectonics The movement of the plates is responsible for the formation of ocean basins, mountain ranges, islands, volcanoes, and earthquakes. Important concepts in the theory of plate tectonics include the following: The ocean floors are continually moving — spreading from the center, sinking at the edges, and being regenerated.

Contracting Earth v. Continental Drift v. Plate Tectonics Well, the pre-continental drift idea went like this. Heavy parts of the crust sank down and lighter parts raised up not only due to the pressure of contraction but also due to isostatic adjustments. The interior of the Earth was thought to be a viscous fluid that could accommodate this sinking and rising.

- Evidence for plate tectonics So what was the evidence for Wegener's theory? Plate tectonics explained why earthquakes and volcanoes were concentrated in specific places - around the boundaries of moving plates. The match in shape between the east coast of South America and the west coast of Africa suggests both were once part of a single continent.

Plate tectonics Plate tectonics is an important theory developed in the 1960s to explain how the continents move across the Earth's surface. Early 20th century geologist Alfred Wegener realised that the puzzle-like fit of many the continents was more than a coincidence, but he couldn't correctly explain what powered their movement.

Activity 3: Plate Tectonics Theory Geologists used a variety of evidence to support their ideas. The following is a history of how scientists developed the theory of plate tectonics, commonly called continental drift. Each word below links you to a form of evidence used to support this hypothesis.

Reply to ASK-AN-EARTH-SCIENTIST Plate tectonics is the over-lying theory presently used by most Earth Scientists to describe motion within the outer-most layer of the solid Earth (also know as the lithosphere). Individual plates of varying size move about the surface of the Earth at varying speeds.

Geology Exam: Plate Tectonics Explain one geologic feature and one natural disaster that result from plate tectonics. One geological feature that can result from plate tectonics is mountains and one natural disaster that can result from plate tectonics is earthquakes (both of these are short-term consequences).

Introduction Plate tectonics is a process that maintains the surface of the Earth in a dynamic and active state. Consequently, it drives such processes as: 1  Magmatism: the primary way in which new elements and new materials are transported as molten rock (magma) from the mantle to the crust.late tectonics is a process that maintains the surface of the Earth in a dynamic and active state.

The Formation of the Rocky Mountains The Formation of the Rocky Mountains. Key Topics. The Mountains Go Up  Mountain Building. To understand the formation of the Rockies, we need to understand Plate Tectonics. According to this theory, the surface of the Earth is made up of a series of plates, each of which move relative to the others. At one time, all the continents were joined into one large land mass known as Pangea.

- No they are not the same thing.    Plate Tectonics is the study of mechanisms and the results of  large-scale movement of the earth's crust.    Tectonic Plates … are large sections of the earth's crust that float  on top of semi-molten rocks of the upper mantle. 3 people found this useful.

- Plate tectonics is the current accepted theory that describes how the face of the earth can change over time. Learning Outcomes After watching this lesson, you should be able to: 1  Describe the plate tectonics theory. 2  Explain what causes plates to move. 3  Identify the lithosphere, asthenosphere, mantle, and core.

- This is a particularly interesting area to study because we can observe two types of plate boundaries (divergent and convergent) and their processes in very close proximity. A divergent boundary occurs when two tectonic plates move away from each other.

- By dating rock recovered from numerous seafloor locations, researchers in the early 1970s confirmed the basic cycle of plate tectonics: New ocean crust forms at mid-ocean ridges and spreads outward toward deep-sea trench subduction zones.

- Take the question somewhat seriously please. If you are interested in plate tectonics you know that the continents and sub-ocean plates are in motion. These can cause earthquakes, but that does not cause the mountain to form, just a symptom. For instance the Indian sub-continent is pushing northward into Asia and meeting resistance.

How has the theory of plate tectonics developed over time? The theory of Plate Tectonics was not developed by a creative genius overnight. It came about through the work of many different people over the course of almost a century. Initially, weak evidence for what was being suggested meant that the theory was ignored and even laughed at for a very long time.

The lithosphere, which is the rigid outermost shell of a planet (on Earth, the crust and upper mantle), is broken up into tectonic plates.

- But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theor … y aren't really two separate things.However plates are pieces of the Earth's crust which are moving.late tectonics is useful in the field of geology because it can be used to explain a variety of geologic processes, including volcanic activity, earthquakes, and mountain building.

What causes tectonic plates to move? This is why I consider plate tectonics pseudo science. Evidence exists in space on or solar system bodies that show moons can be ripped apart and reform and visual evidence clearly shows half a crater on one continent and the other half of the crater on another continent.

Plate Tectonics The word “tectonics” has to do with earth movements; so the study of the movements and interactions among these plates is called “plate tectonics.” Plate tectonics is an interpretation or model of what geologists envisage happened to these plates through earth’s history.

Plate Tectonics History of Plate Tectonics. Plate tectonics grew out of a theory that was first developed in the early 20th century by the meteorologist Alfred Wegener. In 1912, Wegener noticed that the coastlines of the east coast of South America and the west coast of Africa seemed to fit together like a jigsaw puzzle.

Earth Science Concepts Plate tectonics is an important geologic concept as it fills in the gaps to Earth's geologic history. The theory of plate tectonics helps explain the formation of mountain ranges, volcanism, earthquakes and the features associated with active plate boundaries.

plate tectonics According to the theory of plate tectonics, which was proposed in the 1960s, the continents (and ocean floors) ride atop about a dozen semirigid plates—huge slabs of Earth's lithosphere—that are much larger than the continents themselves.

What is the theory of plate tectonics? Plate movements occur because the layer of Earth directly below the lithosphere, the asthenosphere, is hot enough, and under enough lithostatic pressure to prevent its melting…, that it can deform without fracture.

- Mountain Building Studies of the mountain ranges and the mapping of plate boundaries associated with plate tectonics give us a picture of the process of mountain building. A unique feature of the Earth in the solar system is the presence of linear mountain ranges caused by the convergent boundary of two tectonic plates.
