what is the link between earthquakes and the movement of tectonic plates?

Tectonic Plates, Earthquakes, and Volcanoes. According to the theory of plate tectonics, Earth is an active planet. Its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates.

There are places on the earth where the movement of the plate causes them to collide. These collisions cause convergent boundaries. The collisions of large masses of the crust result in mountains ( such as the Himilayans ) , earthquakes ( such as the San Andreas fault) .

Plate tectonics is the name of the concept that the surface of Earth consists of separate plates moving independently of each other. Continental drift is the result of plate movement and causes continents to move in relation to each other.

Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.

Earthquakes likely occur in Convergent and Transform boundaries. What happens when plates move apart? When plates start moving apart the magma from the Earth's core rises up and new crust is created.

When that happens, the Earth's surface is subject to natural disasters. Events such as earthquakes, volcanoes and tsunamis all result because of plate tectonics.

Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig.

Places where plates slide past each other are called transform boundaries. ... Although transform boundaries are not marked by spectacular surface features, their sliding motion causes lots of earthquakes. The strongest and most famous earthquake along the San Andreas fault hit San Francisco in 1906.

Subduction zones are plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other. This process results in geohazards, such as earthquakes and volcanoes.

Tectonic plates are formed and move apart at mid-ocean ridges. Some portion of this plate-separation process can occur by stretching of the crust, resulting in a complex pattern of extensional faults. Abyssal hills, the most ubiquitous topographic features on Earth1, are thought to be a product of this faulting2,3.

Interactions between the North American Plate and the Pacific Plate produce California's mountains and basins and cause earthquakes and volcanoes. Any process that moves Earth's surface to a higher elevation. * The San Andreas Fault is a boundary between two adjacent plates.

Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.

The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.

Three of the forces that have been proposed as the main drivers of tectonic plate movement are: mantle convection currents— warm mantle currents drive and carry plates of lithosphere along a like a conveyor belt; ... The cooler sinking plate pulls the rest of the warmer plate along behind it.

Plate boundaries are always faults, but not all faults are plate boundaries. The movement of the plates relative to each other distorts the crust in the region of the boundaries creating systems of earthquake faults. ... When this wave reaches an observer, the rapid motion of the earth is interpreted as an earthquake.

Answer Expert Verified. Volcanoes, earthquakes and mountain ranges are all results of the tectonic movement of the Earth. When two plates collide and one does not completely give way and go under the other the crust is pushed up forming mountain ranges.

Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates.
