Igneous Rocks Research Paper

As a tectonic plate slides into the mantle, the heat releases fluids trapped in the plate. Seawater and carbon dioxide, rise into the upper plate and can partially melt the overlying crust, forming magma. And magma most likely means volcanoes are around.

Volcanos are deadly, can form on islands or mainland, and can destroy mountains and cities. Volcanos commonly form from holes in the earth containing magma. When pressure builds up in these magma chambers, they explode resulting in magma and rock catapulting out into the air. As these volcanoes repeatedly explode, they leak magma, which runs down the side of the volcano. Eventually, the lava cools and transforms into solid rock, building up the volcano to mountain size. An example of giant volcanic eruptions is the Pompeii disaster in 79AD, when Mount Vesuvius erupted and destroyed all of Pompeii. Another example includes, the 1980 eruption of Mount St. Helens in Washington state, which destroyed the whole mountain. Volcanos

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

The Earth’s outer crust is made up many tectonic plates that move over the surface of the planet. When the plates come collide, volcanoes will form sometime (National Ocean Service). Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot” (National Ocean Service). A hot spot is a plume of magma or molten rock that rises from within the Earth then reaches the surface forming underwater volcanoes which may grow tall enough to

Convection currents may bring magma to the surface at diverging boundaries. Sedimentary rocks from the ocean floor gets pushed down to the mantle at convergent boundaries. The crust soon melts and rises to the surface creating igneous rock. Typically mountain ranges are metamorphic rock, maybe our mountains are.

Initially, earthquakes shape the Earth’s surface by creating mountains and geysers. In the article “Historic Earthquakes,” it reads, “High intensities were observed in the northwest section of Yellowstone National Park. Here, new geysers erupted, and massive slumping caused large cracks in the ground from which steam emitted” (Stover 3). Consequently, when the geo-process of earthquakes occurs, it molds and changes the earth by creating new geothermal

Some rock’s in the Earth’s interior that are solid, are so hot that, if the pressure on these were released, or they are convected into a lower pressure zone, they could begin to melt

Metamorphic rocks are the result of the transformation of a pre-existing rock type, the protolith, in a process called metamorphism, which means "change in

What is a volcano: A volcano is a mountain created by the earth. It also creates a hole where molten rock (lava) erupts. A volcano is filled of magma but when the magma erupts and is out of the volcano it is now called lava. When a volcano erupts it fills the air with lava fragments. A volcano can cause a lot of destruction like tsunamis, flash floods, mudflows, rockfalls, and earthquakes. Most volcanoes are located where the tectonic plates meet. Most

To begin, a volcano is a mountain with an opening in the top or side that sometimes sends out rocks, ash, lava, in a sudden eruption (Merriam-Webster, n.d.). A volcano erupts when pressure builds inside the mountain. Magma, lava while it is inside the volcanoe, pushes through the weakened crust. When this built up pressure is released, Earth’s plates move causing a volcanic eruption. Also, dangerous flows of steaming lava can reach up to 2,000

A volcano is a mountain built when magma rises from Earth's interior to the surface of the Earth.Volcanoes erupt when the pressure of the melted rock inside becomes so high that it blows through the solid surface of volcano. This explosion leads to many economic difficulties just like it did when Mount St. Helen exploded. It is a devastating event and clouds of ash, dust, and gases flowed into the environment. These fumes can be difficult to breath in and the damage it can cause wildlife is also

Besides the obvious, I also have to worry about earthquakes. Not all volcanoes are related to earthquakes, but it can happen. When the magma reaches a rock, and pressures it too hard until it cracks, the magma squirts into the crack and creates a pressure again. Every time a rock cracks, it causes a small earthquake. As we can see here, it is not that common for an earthquake to happen, but I also do not want to be part of the statistics.

Volcanos typically formed as a consequence of plate tectonics. In fact, they tend to form when plates converge into each other. In the process of subduction, one plate of the lithosphere, cupped by oceanic crust, slides beneath another one, giving origin to a subduction zone. While sliding down, heat is generated and water is released, causing the formation of magma that rises up to the surface and forms volcanos parallels to overriding plate. The Pacific West region of the United States is known for presenting this type of structure in which the oceanic lithosphere pushes towards the continent and sinks down into the asthenosphere.

     Metamorphic rocks are pre-existing rocks that are changed by heat and pressure. The pre-existing rock is called the parent rock, or protolith. Metamorphism occurs in these rocks when the minerals become instable. There are two types of metamorphism, contact and regional. Contact is high temperature, low pressure. It is basically a massive rock that is baked. Regional is high pressure and low temperature. Strong fabric, or layering, develops from
