500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. The role of plate tectonics in the origin of igneous rock is extremely important. Igneous rock is formed from magma that reaches the continental and oceanic crust or through hot spots that are around the world. There are three different places where igneous rocks can form; where the lithospheric plates pull apart at mid ocean ridges‚ where plates come together at seduction zones‚ and where continental

Geo assessment Mt Etna An eruption begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. When the magma chamber has been completely filled‚ the pressure in the pipe will build up very high resulting in an explosion. When magma reaches earth’s surface it is called lava. It may pour out in gentle streams called lava flows or erupt violently into the air. Rocks ripped loose from the inside of the volcano or torn apart by the gas may be shot into the

Through the years humans have evolved beyond our expectations‚ while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume‚ the environment is constantly being affected. First the very stuff we breathe

of Northridge in 1994 that occurred along one of the San Andreas’s larger secondary faults. The San Andreas Fault is a conservative boundary between two major plates of the Earth’s crust: the Pacific to the south and west and the North American to the north and east. The Pacific plate is sliding laterally past the North American plate in a northerly direction‚ and hence the San Andreas is classified as a strike-slip fault. The annual rate of movement has been 4 to 6 cm per year since the early

The legend of Atlantis‚ the lost continent described in a story written by Plato around 360 B.C.‚ has inspired heated speculation for many centuries. In modern times‚ public interest in the subject has been accompanied by imaginary proposals that stretch Atlantis well beyond the boundaries of Plato’s story. Nowadays‚ it’s quite difficult to distinguish Atlantis facts from Atlantis fiction. The documentary by the History channel called “Atlantis: Searching for the Lost World of Atlantis” starts

Plate Tectonics Plate Tectonics The theory of plate tectonics was developed in the 1960’s and states that the earth is broken into a number of shifting plates. Plate tectonics also provides geology with a comprehensive theory of how the earth’s crust moves. In this essay I will explain the different types of plate movements‚ how the plates move and how this movement affects earthquakes and volcanoes. To begin‚ there are three different types of plate movement; divergent boundaries‚ convergent

At the entrance to a home in Japan‚ the floor will usually be raised about 6 inches (15.24 cm.) indicating you should take off your shoes and put on slippers. If the house has a tatami mat room‚ its floor may be raised 1-2 inches (2.54-5.08 cm.) indicating you should take off your slippers. 2. Interested. 3. Tonight I
