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

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

Earthquake‚ shaking of the Earth’s surface caused by rapid movement of the Earth’s rocky outer layer. Earthquakes occur when energy stored within the Earth‚ usually in the form of strain in rocks‚ suddenly releases. This energy is transmitted to the surface of the Earth by earthquake waves. The destruction an earthquake causes depends on its magnitude and duration‚ or the amount of shaking that occurs. A structure’s design and the materials used in its construction also affect the amount of damage

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

better understanding of both the mechanics of volcanoes and the dangers they present to the environment and communities. Did you know that volcanic ash is actually small glass particles? Or that the majority of volcanoes are submarine? Understanding some of these different facts can help us to understand the earth’s volcanic processes. Volcanoes erupt different materials and those can become different after cooling. Things like lava‚ gases

There are many different reasons why the earth’s crust is moving. Some for example are the friction between two plates causing major earthquakes. Sometimes when this plates are pushed together they form fold mountains or ridges. Today we know that the continents are gradually moving apart. Therefore the there is new rocks created in between those areas. New volcanoes are created and new rocks are formed. Plate tectonics allow scientists to know about the earth’s centre. The oceanic plate slides

restless quickly and earthquakes do occur. NASA also tested a robot named “Dante” at volcanoes in Alaska and Antarctica. The Lakes near volcanoes can become acidic enough to be dangerous to people(pH of water was tested initially. There was seismograph readings in the movie and the carbon dioxide can kill tress and wildlife. Unrealistic Points in the Movie The lava flows were too fluid when it should have been thick and slow moving. The temperature of hot springs near volcanoes changes more slowly

other hand‚ Tsunamis can be caused by a few different factors‚ which are an earthquake‚ a large-scale undersea landslide‚ a submarine volcanic eruption (Cause of Tsunami‚ n.d.). Firstly‚ the vast majority of tsunamis results from the earthquake. The earth ’s surface is covered by the continents and sea floor which are parts of the world-wide system of plates that are in the very slow motion. An earthquake occurs where the edges of plates run into one another‚ which are called faults

the coast of the Hawaii Island. It is 969 meters below the sea surface and 3‚500 meters above the ocean floor. 17. This new island is forming because the Pacific Plate is moving in a northwest direction‚ and as it moves toward the “hot spot”‚ new volcanoes will form‚ which makes Loihi the “new” volcano. 18. In Hawaiian‚ Loihi means long‚ which also describes the shape of this new island being long. It has two curving rift zones in both the north and the south summit‚ and has a caldera that is about
