Subduction

There are many different aspects in the world of geology. Something that I want to focus on are hydrothermal vents. Hydrothermal vents are like chimney shaped hot springs that are located on the ocean floor. Hydrothermal vents were first discovered in 1977 near the Galapagos Islands in the eastern Pacific. Scientists exploring the area along the mid-oceanic ridge had noticed drastic temperature changes in their data. With the help of ALVIN, a research deep sea submersible, they discovered vents…

Over the years, earthquakes have acted as one of the most lethal calamity in the world among other disasters. They have claimed millions of lives and numerous properties in the world since documentation of the earthquakes begun. Naturally, some areas have never experienced any earthquakes while other areas are said to be precisely in the hot zone where the probability of occurrence remains high. In the recent past, about 500,000 earthquakes are reported to happen every year. Of this, a human…

side of the plate, along Central America, there have been way bigger eruptions than the west side. The west side of the plate has also had a lot more, deeper earthquakes than the other sides of the plate. The Cocos and Caribbean plates could have subduction occurring, considering that the west side of the plate has a lot more height directly next to a deep trench, a lot of earthquake and volcanic activity, and the sea floor is a little older in that…

Section 1: Plate tectonics is the the theory that the outer crust of the earth is cut up into a lot of pieces called plate tectonics. The plate tectonics move around in the mantle. The mantle is the rocky middle layer of our earth it lies right above the core. The plates are very much like a shel going around the earth. The evidence of plate tectonics began as simply circumstantial evidence one example is continental drift which is the theory that all the continents used to be one giant…

The Inner Core, Outer Core, Mantle, Asthenosphere, and Lithosphere, or, as more colloquially known, the five layers of the Earth. Although each layer is important, each living thing resides on the Lithosphere, which happens to rest on the Asthenosphere, the upper part of the Mantle. Forces caused by these two layers both contribute to the theory of Plate Tectonics, which happens to be interconnected to Earthquakes and Volcanoes. Without Plate Tectonics, the other two occurrences simply cannot…

Taupo Volcanic Zone The Taupo Volcanic Zone is a highly active volcanic region situated in the central part of the North Island in New Zealand. The Taupo Volcanic Zone (TVZ) stretches from Ohakune in the south of the Bay of Plenty to White Island in the north. It is estimated that the Earth’s crust below the Taupo Volcanic Zone may possibly be as small as 16 kilometers think and currently moves approximately 8mm per year. The TVZ is named after Lake Taupo, the caldera of the formaly largest…

Plate tectonics is a theory about how the plates are constantly moving on top of a layer of magma that is constantly taking in old crust to recycle it this constant movement causes earthquakes, tsunamis and other geological events. The movement of the Pacific and North American plates cause the old sea floor to be replaced by the now wider North American plate. Also with the movement the continental plate was stretched as the Pacific plate pulled the continental plate to the northwest which…

I believe that there are no plate tectonics on Venus. I believe this because of the reasearch that i did on this topic. Venus shows no evidence of plate tectonics on it's planet. " There are no long, linear volcano chains or any clear subduction zones. The transform plate boundary, causes the plates to slide past one another, which may cause earthquakes or fault lines, which is exactly what is happening. The plates are sliding past one another and earthquakes ar occuring which may lead one to…

Earthquakes and volcanoes go hand in hand like peanut butter and jelly or rice and beans. Where there are volcanos there are usually tectonic plates beneath them either pushing against or pulling away from one another. Take for instance the Cascade Mountain Range in Northern California and stretches through Oregon and into Vancouver, British Columbia and sits northeast of the San Andreas Fault line that runs 750 miles through California. This fault creates the tectonic boundary between the…
