These creatures, over hundreds of thousands of years, are able to change their DNA to adapt to their environment, which is an incredible thought. However, on Earth, the land is always changing, and everything will soon evolve once more to be fit in their habitats. Two hundred million years ago, there was a large supercontinent called Pangea, a strange formation of all seven continents that exist today. Pangea was the largest landform ever to exist on this planet, but was pushed apart by plate tectonics. Earthquakes and waves pushed the supercontinent apart, showing how strong that tectonic plates can be.
Analysis There are lots of different types of volcanos, but they can be divided in three main types. The first one is the stratovolcanoes. It’s called like that after the Latin word “strato”, which means layer. They are usually high mountains that can erupt with a lot of power. They are so high because of the many eruptions that already happened here.
Tsunamis happen when the plates on the crust of the earth move, therefore moving the entire plate so that the water rises and is pushed forward, therefore causing a tsunami (Drohan, 2009, p.21). These tectonic plates are everywhere, under everything from the biggest mountain to the smallest hill. Though it is infrequent, volcanoes have been known to cause tsunamis. It happens when to volcano begins to erupt, but instead of coming out from the top of the volcano a lateral blast shoots out from the side. Next, a quickly moving avalanche of lava pours into the water near it causing the wave to travel to distant coastlines (Springer, 2005).
Igneous rock (derived from the Latin word "Igneus" meaning of fire, from "Ignis" meaning fire) is one of the three main rock types (the others being sedimentary and metamorphic rock). Igneous rock is formed by magma (molten rock) cooling and becoming solid. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition.
theories and ideas presented thus, not generally accepted. In the 1960s, plate tectonics emerged that explained Earth’s features such as continents, oceans, volcanoes, earthquakes, valleys and mountains. This theory became widely accepted by virtually all Earth scientists. A plate is a solid rock that is large and rigid while the Greek word tectonics means ‘to build’. Plate tectonics is the study of how the surface of the Earth is formed, how the separate pieces of it moves and the effects of this movement (Cambridge Dictionaries, 2014) Understanding the dynamic planet upon which we live has been made and transformed significantly although the concept is fairly new.
The earth wasn’t always solid. Billions of years ago it was a blob of magma floating in space. Over time the surface cooled, but the centre remained molten rock. The pressure and heat broke the surface into plates that float on a sea of magma below. These plates are constantly moving, drifting apart creating divergence boundaries and crashing together creating convergence boundaries, colliding with the power to forge mountains, and splitting solid rock like it was paper.
Mid-ocean ridges are sub-surfaced mountain ranges located at the boundaries between the tectonic plates that make up the Earth’s crust (van Dover, 2000; Tivey, 2007; Martin et al., 2008). As the plates are pulled apart by tectonic forces, hot soft rock from the deep Earth emerges to fill the fissure. As the generated ocean crust laterally moves away from the spreading-axis, the age of the crust and the depth of the sediment cover increase systematically (van Dover, 2000). Therefore, different types of hydrothermal vents occur at different areas of the ultramafic sea floor. The simplest of these are the columnar sulfide chimneys at the East Pacific Rise (EPR).
A subduction zone is the place where one tectonic plate slides underneath another. However, in this case, the North American tectonic plate is stuck and is wedged against the oceanic plate called Juan de Fuca. With all the pressure building up, the edge of North America is bulging upward at a rate of over an inch each year. There is a stopping point and soon North America will suddenly spring out and push back the other plate. If the whole zone moves, then it is predicted that this will create a full rupture with a magnitude between 8.7 and 9.2.
One example being, fracking, which is the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc., so as to force open existing fissures and extract oil or gas. When contractors frack they create manmade Earthquakes. At 5:12 AM on April 18, 1906, the Great 1906 San Francisco Earthquake occurred. The rupture was about two hundred and ninety six miles. According to eyewitness
The great heat from this localized hotspot melts the Pacific plate above the hotspot and the spreading seafloor along the plate boundary pushed over the rocky crust. Magma was produced from the melting rock of the Pacific plate. The magma rise through the mantle and the crust as a thin thermal plume because magma is less dense than the solid rock of the plate. It was erupting beneath the ocean to form an active seamount. With the countless eruptions under the sea, the height of seamount keep increase until it breaks the ocean surface and becomes an island volcano.
