Which Best States the Theory of Plate Tectonics

The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. The Andes Mountain Range of western South America is another.

Rich people in the United States have the best standard of living in the world but the poor can get trapped in cycles of poverty far stronger than other Western.

. One of the best examples of this type of disjunct geographic distribution is that of. Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earths subterranean movements. However what he got right paved the way for plate tectonics theory.

Oceanic and continental plates come together spread apart and interact at boundaries all over the planet. The edges of the plates are marked by concentrations of earthquakes and volcanoes. Each type of plate boundary generates distinct geologic.

The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates which float on the fluid-like visco-elastic solid asthenosphere. Data Supporting Continental Drift Theory. The best example is the San Andreas Fault on the Pacific coast of the United States.

Before the advent of plate tectonics however some people already believed that the present day continents were the fragmented pieces of preexisting larger landmasses. The United States is comprised of a vast variety of landscapes places and people. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate.

Like the scientists before us we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics. The theory of plate tectonics states that the Earths outermost layer is fragmented into a dozen of large small plates that are moving relative to one another on top of the mobile Asthenosphere. Similar fossil remains such as those of the Triassic land reptile Lystrosaurus and the fossil plant Glossopteris exist in.

By the large-scale process of plate tectonics about twelve plates which contain combinations of continents and ocean basins have moved around on the Earths surface through much of geologic time. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.

IRIS is a consortium of universities dedicated to the operation of science facilities for the acquisition management and distribution of seismological data. Theory of Plate Tectonics. The second revolution was the development in the 1960s of the theory of plate tectonics The Earths outer layer the lithosphere is divided into rigid rocky plates comprised of continental and oceanic crust that move over the surface of the Earth by sliding on the plastic upper layer.

The theory of plate tectonics states that the Earths solid outer crust the lithosphere is separated into plates that move over the asthenosphere the molten upper portion of the mantle. This map shows 15 of the largest plates. Line of best fit animation Order form.

The San Andreas Fault links the East Pacific Rise off the West coast of Mexico Gulf of California to the Mendocino Triple Junction Part of the Juan de Fuca plate off the coast of the Northwestern United States making it a ridge-to-transform-style fault. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions. Collisions of plates can produce mountains like the Himalayas the tallest range in the world.

Explore the physical and human characteristics of land water and populations across the nation. Fossil remains of similar organisms on widely disparate continents support the theories of continental drift and plate tectonics. It varies by socioeconomic status.

When the concept of seafloor spreading came along scientists recognized that it was the mechanism to explain how continents could move around Earths surface. The theory which solidified in the 1960s transformed the earth sciences by explaining many phenomena including mountain building events volcanoes and earthquakes.
