Plate Tectonics Plate tectonics is the manner of which the Earth’s lithosphere moves around. The weakness of the Earth’s upper mantle allows the Earth’s lithosphere to move. The lithosphere is not a single unit, it is broken down into a series of plates. The result of plate tectonics movements result in large catastrophes and natural disasters. Why do plate tectonics move ? The mantle of the Earth is very weak so, the rigid structures of the lithosphere move around easily. Tectonic plates move easily over the mantle because, they are just floating there. The heat of the Earth causes the magma in the liquid mantle to expand and move. The heating and moving of magma causes the tectonic plates to move. The plates move in a pattern called a …show more content…

Earthquakes, tsunamis, and volcanos have all caused significant damage to the Earth and the people of it. Earthquakes can cause huge buildings to crumble, the ground to subside, flooding when a dam/ levee breaks, and fires caused by broken gas lines. People can be crushed by huge buildings collapsing, drowning from the flood caused by the broken levee or dam, getting buried under a landslide, or even getting burned alive by a fire from a broken gas line. Tsunamis can cause major flooding, a great number of casualties, and the total destruction of houses of buildings. People die from drowning, collapsing buildings, electrocution from power outlets, diseases, and explosions of gas from damaged tanks and other floating debris. Lastly, volcanoes can also cause large amounts of damage. Volcanoes cause; earthquakes, mudslides, fast floods, rock falls, and huge amounts of ash to be discharged. Houses, buildings, roads, and fields can collapse when covered with hot ash. Harmful gasses that are emitted from a volcano can get into your respiratory system and make it hard for you to breathe, causing death. Cities and towns are destroyed by mudslides, ash, and the earthquakes caused by a volcanic eruption. When plate tectonics move they cause all of these terrible things. The number of casualties are constantly rising because of these natural disasters and their effects on

    Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...

  • Comparison Of Haiti And Japan Earthquake

    Earthquakes happen about 20,000 times a year worldwide. They can destroy almost anything.In 2011, Japan had 9.1 magnitude earthquake, close to the highest magnitude of 9.2 in Alaska. They suffered tremendous damage from such a strong earthquake. The year before Haiti suffered from a 7.0 magnitude earthquake, still quite high compared to small tremors at magnitude 0-2. Japan recovered and rebuilt much faster than haiti did though. Haiti isn't even quite done recovering yet. The earthquakes had such different effects on the countries because of their economy, the condition of their people, and population rates.

  • Thromas By Zeta Stevens Why Do Earthquakes Occur?

    1145 Words  | 3 Pages

    The earth is split into four layers, inner and outer core, the mantle and crust. The top of the mantle and crust make up what is like the skin of our earth (see source 2). The skin is split up like a puzzle and we call these puzzle pieces’ tectonic plates (see source 1). These plates are constantly moving and the plate boundaries (edges of the plates) move and slide past one another. Sometimes as the plates move the plate boundaries become stuck. Pressure builds up in the stuck area over time and eventually breaks. This is why earthquakes occur due to the sudden movement of the plate sliding and breaking creating a fault line to go off. The fault line is the line on which the

Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.

  • A Tsunami in Santa Cruz

    464 Words  | 1 Pages

    Out of all the natural disasters that we talk about in class, the most deadly would have to be a Tsunami. Compared to earthquakes, Tsunamis have cause more deaths since 1945. A Tsunami is likely to strike anywhere on the west coast, including Santa Cruz in California – United States – North America – 36:58:24N 122:02:09W. A Tsunami is a giant “wave” of water that is caused by a sudden shift in the sea floor. The wave is a result of the water attempting to regain its equilibrium, which is driven by gravity. The size of the wave is determined by how much the sea floor is moved vertically, and how quickly it shifts. A greater water depth helps as well. They can travel up to five hundred miles an hour and have wave heights of one hundred feet. Earthquakes are the leading cause of Tsunamis. People who live in California are well aware of earthquakes that are frequently caused by the San Andreas Fault. However, not many are aware of the results of earthquakes that occur out in the Pacific Ocean. Tsunamis have also been referred to in the past as seismic sea waves, but Earthquakes aren’t the only cause of this phenomenon. Landslides, nuclear explosions, volcanic eruptions, and extra terrestrial impacts also have great water displacement results.

    First you might need to know definition of tectonics. It is a theory in geology. The lithosphere of the Earth is divided into a small number of plates which float on and travel independently over the mantle and much of the Earth’s seismic activity occurs at the boundaries of these plates. That is the official definition of Plate tectonics. secondly, this plate covers many parts of continents. plate boundaries don’t go according to Continents boundaries, they make their own boundaries. The North American plat...

    Why do the continents move everyday? what is causing them to is caused by glaciers falling into the ocean for example rockford was caused by a huge glacier that’s why there are lots and lots of fossils at rockford, because the glaciers carried the fossils to rockford. the evidence of glaciers forming would be ice sheets and ice chunks were found on land and in the ocean, and it affects the earth because it’s putting more water into the oceans. plate tectonics also may have caused the glaciers to fall into the ocean when the plates move which causes the the glaciers to fall. Plate tectonics is the theory that earth’s outer core shell is divided into several plates, there are three different they are Convergent,Divergent, and Transform they all

    Convection currents deep in the mantle of the earth, begin to well up towards the surface. As the pressure increases, it sets the crustal plates in motion. There are different kinds of mountains - Volcanic, Folded, Fault-block, and Dome mountains. Volcanic mountains are formed when magma comes up through cracks in the Earth’s crust and explodes out of lava and ash. The Hawaiian volcanoes, Mt. Hood, Mt. Etna, Vesuvius, and Mt. Saint Helens is an example of volcanic mountains.

    ... of fire in the Pacific Ocean. This is the boundary between the Pacific plate and several other plates. Also, the San Andreas Fault, in California, which is situated on the boundary between the Pacific and North American Plates, sees a large amount of earthquake activity. Another dangerous effect of plate movement which is common in the Asian Pacific is the Tsunami, a huge ocean wave created by earthquakes and plate movements deep under the ocean’s surface. While these events can all be seen as natural disasters, the benefits tectonic plates have to offer the human race are plentiful. Volcanoes produce some of the most fertile soil on earth, while magma that does not erupt from a volcano often forms huge ore deposits beneath the surface. A relatively young science is that of geothermal energy, or the harnessing of heat or pressure from volcanoes, geysers and steam which can be converted into heat and electricity for human use. While it is important to acknowledge the immediate and disastrous ramifications of plate tectonics, such as volcanoes and earthquakes, it is equally as imperative that humans recognize the huge potential for advancement provided by this natural occurrence.

    Plate tectonics is the theory that landmasses on tectonic plates are in slow constant movement due to convection currents in the mantle. Plate tectonics, or the movements of plates above the lithosphere (the most upper layer of earth's crust) can cause divergent, convergent,and transform boundaries.A boundary the way two tectonic plates collide. is Continental plates are plates that the continents are formed on. Oceanic plates are plates that the ocean covers, and the oceans form on top of these plates. Convergent boundaries and divergent boundaries are ways that these oceanic and continental plates interact with each other. Landforms are formed at boundaries. The landforms formed at boundaries depends on the type of plates that collide, and

    The concurrent convective circulations in the mantle leads to some segments of the mantle moving on top of the outer core which is very hot and molten in nature. This kind of movement in different segments occurs as tectonic plates. These tectonic plates are basically seven on the earth surface as major ones, although, several small ones exist also. The plates motions are characterized by varying velocities, this variance results to sub sequential collision of two plates (leading to formation of a mountain in a convergent boundary), drift of two plates (leading to formation of rifts in a divergent boundary), or parallel movement in a transform boundary(Webcache 3).
