Planetary volcanism Essay Example | Topics and Well Written Essays - 500 words

Planetary vol hindquartersism - Essay ExampleBecause of truly game temperature in the inner core of the earth, the interior material is usually in molten earth (Greeley, 2013). When both plates move further apart, the earths interior materials progressively rise up and plight the vents created by plate movement. Magma chambers may also form in cases where plate move all over each other. Despite the fact that volcanism on earth usually takes place at boundaries between plates, it can also happen at the hotspots inside the plates interiors. Very high temperature of the earths interior causes materials within the inner part to melt. This molten material is then ejected to the earths surface under high pressure. When magma reaches the surface of the earth, it solidifies into thick lava, which eventually forms volcanic rocks. Volcanoes on earth ar mainly categorized into two shield and composite volcanoes (Greeley, 2013).Evidences of volcanism have also been noticed in the Earths m oon. The moon is characterized by small volcanoes, crevices as well as widespread basalt lava flows (Greeley, 2013). The moons large and dark basins, ofttimes called the mare, are flows of lava. However, there exist no sign of active volcano on the moons surface and all the evidences of volcanoes are archaic. Volcano in the planet moon, occurred millions of years ago and no novel volcanic activity has been observed in the recent past. impair also has exhibits of volcanism. The planet has volcanic features that are akin to those on Earth, but a bit larger. deflower has shield volcanoes with Olympus Mons (22 kilometers) being the solar systems tallest volcano. The Tharsis region hosts most volcanoes in Mars (Kusky, 2005). Similar to volcanoes on Earth, the volcanoes in Mars are believed to have formed from materials ejected from the deep and hot interior of the planet. Unlike the Moon, many scientists believe Mars has active volcanoes. Basalt meteorites are perfect
