Hello, I am looking for someone to write an article on Formation of Volcanoes on Earth and Other Planets. It needs to be at least 1500 words. The inner part of the earth is made up of two cores, inner and outer nature after the body is a highly viscous mantle and the solid crust. The outer core is liquid while the inner is solid. The high temperatures and pressure inside the earth make the mantle to be in a dense state. Inside the world, the rocks found in the cover and core are still hot after the planet was formed billion of years ago. According to the scientist, as the earth was being developed, the materials that make up the earth collided at high speed, the high-speed collision generated heat, and it remains trapped inside the world while the surface cooled (Haraldur and Broughton 36). Apart from that, radioactive elements within the earth produce heat through radioactive decaying. Since the planet is large, the radioactive elements have a lot of heat, and it is shielded from reaching the earth surface by rocks, rocks are well known to be good insulators. The heat is capable of melting specific stones found at the upper mantle. Rocks at that layer are made up of several minerals, and each mineral has its boiling point that means when a rock starts to melt, some minerals melt faster than others (Haraldur and Broughton 36).Formation through a volcanic eruption When a rock melts and forms liquid or semi-liquid, its density becomes less as compared to the surrounding rocks. Due to the difference in thickness, the magma is pushed upward by pressure, the heat resulting from this pressure melt some stones on the way. The molten material looks for a way into the earth surface through cracks resulting from weak points, it exerts pressure on the cracks so as to escape (Haraldur and BHoughton 36).When it reaches the earth surface, the magma is then referred to as larva. the larva will then form volcanic mountains after cooling. The hills may grow bigger because some volcanoes erupt severally after a certain period forming different layers. Weak points between the magma and the earth surface enable eruption. strong earthquakes sometimes accompany the outburst of magma. The flow of magma is determined by things such as pressure, amount of gas, and mineral content.
