Why do earthquakes and volcanoes occur at plate boundaries? A.Plate boundaries undergo much tension and friction. B.Temperatures fluctuate greatly at plate boundaries. C.Earthquakes and volcanoes cause new plates to form. D.The causes of earthquakes and volcanoes are unknown....
During subduction, as one plate dives into the depths beneath another, we think part of the rock melts and eventually finds its way back to the surface in the form of volcanoes. In fact, most of the world"s volcanoes and earthquakes occur at plate boundaries. This is what you"d expect....
and we said that most of the world's volcanoes occur at the boundaries of these tectonic plates where you have hot molten rock squeezing up through gaps between the plates. But some volcanoes occur not at the edges, but in the middle of a continental or oceanic plate. The Hawaiian Islands...

The Pacific Plate is slowly speading away from its neighbors. (Map by John Nelson from NASA Visible Earth satellite imagery and tectonic plate boundaries from Hugo Ahlenius) Slide 1Slide 2Slide 3 Transformation and Destruction For starters, what happens in the ocean doesn’t stay in the ocean...
Conversely, in places where the plates collide—called convergent boundaries—one plate will often slide under the other. This process, called subduction, produces many of the planet's mountain ranges and volcanoes. Subduction can be a violent process. It's no coincidence that mostundersea earthquak...
Plate Tectonics: The theory of plate tectonics deals with the dynamics of the earth's outermost layer (also known as the lithosphere). The theory gives a satisfying explanation for the formation of structures like mountains. ridges, volcanos etc. According to the theory...
And of course an absolutely nightmarish earthquake could occur along the New Madrid fault at any time, but that is a topic for another article. As far as the Ring of Fire is concerned, another major threat is volcanic activity. One of these days, one or more of the major volcanoes on ...
Why do earthquakes occur before a volcano erupts? Why do earthquakes often happen near volcanic regions? Why are most earthquakes and volcanoes at plate boundaries? Why is Mount Pinatubo considered an active volcano? Why do tectonic plates exist? Why do tectonic plates move? Why do most earthquak...
Unlike Earth, on Venus, no plate tectonics exist which could help to hide old craters. If all the water in Venus’s atmosphere were condensed into a layer on the surface, it would be only 10 cm deep. And the ratio of deuterium to hydrogen on Venus suggests that a huge amount of ...
