America. Mount Saint Helens is known to be one of the top 10 most famous volcanoes in the world due to the deadly pyroclastic flows and ash explosions well known to it. A volcano is a mountain with a vent at the top where magma and gasses from the earth’s Mantle erupt on the earths crust and turn into lava caused by the movement of the tectonic plates. Tectonic plates are big pieces of the lithosphere that

“Discuss the Extent to which volcanic and seismic activity are evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported

relating to earthquakes and volcanic activity can be explained by plate tectonics. If you follow news stories of earthquakes‚ you may begin to wonder why such places as California or Japan have so many earthquakes‚ whereas the north eastern United States or Western Europe have so few. The fact is that earthquakes occur along belts and the vast majority of these belts lie on the boundaries of the earth’s tectonic plates. The same is true of volcanoes and locations known for earthquakes‚ such as the

major city in the United States. Hurricane Katrina tore through the city with a vengeance leaving thousands destitute and stranded for days. Areas such as California have high risk of earthquakes at any given moment. For years the western coast of the United States has had its fair share of experiences with earthquakes. But‚ what region or pocket of this country is safer than any other. Deciding the safest place to live in the United States can be a matter of opinion based upon what a person may feel

Pacific Ring of Fire (or just The Ring of Fire) is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40‚000 km (25‚000 mi) horseshoe shape‚ it is associated with a nearly continuous series of oceanic trenches‚ volcanic arcs‚ and volcanic belts and plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.[1] It is sometimes called the circum-Pacific belt or the circum-Pacific seismic

These borders are regions of intense seismic activity‚ including frequent earthquakes‚ occasional tsunamis and volcanic eruptions. * Plate tectonics give rise to fold mountains‚ earthquakes‚ volcanoes‚ island arcs and ocean ridges.

Jaesung Lee Geography 1 Professor Thomas Orf Chapter 14 Questions 1) The first evidence Wegner was able to find was the remarkable number of close affinities of geologic features on both sides of the Atlantic Ocean. He found the continental margins of the subequatorial portions of Africa and South America fit together with jigsaw-on-like precision. He also determined that the petrologic records on both sides of the Atlantic show many distributions- such as ancient coal deposits-that would

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new science. It’s partially explained in the sense that we still don’t know fully about how the plates came together‚ what they were before they were the seven continents we know today. We already know‚ or have a theory‚ about what our world was like a long time ago and so if we already know that the plates can pull and push against each other‚ then surely
