The Two Main Layers That Caused The Earthquake And The Asthenosphere

point in time, has a great influence on understanding all aspects of living things, either in the past, present, or future. The Theory of Plate tectonics is accredited to most of the creations of Mountain Ranges, the Centennial drifting Theory, for earthquakes, and volcanic activity. Plate tectonics and mountains also play a big part in the Earth and its geological features. Geophysics, which studies the physics of the Earth, has led to many important findings about the Earth and how it is made. Seismologic

and the continents, producing earthquakes, volcanoes and uplifts. This paper will discuss the composition, movement and history of tectonic plates, the theory of plate tectonics and its history, and tectonic plates affect the surface of the earth today and will continue to do so in the future. The earth is divided into three main layers: the core, the mantle and the crust. The core is further divided into the solid inner core and the liquid outer core. This layer is mostly iron and nickel and

released from earthquakes and forces that move crustal plates are derived from the internal heat engine. Liquid water can exist on earth because the orbit is at the proper distance from the sun. The ozone layer is important to life on earth because it shields living things from uv rays. Constant change and state of flux on earth is caused by slow moving convection currents in the mantle. The internal heat of earth is a result of heat from radioactive decay of certain elements. The main cause of over-use

Earthquakes happen all round the world daily and they are extremely dangerous. An earthquake is caused by the movement of plates called fault. Plates are segments of the outermost rigid shell of the Earth, composed of the crust and attached upper mantle, which float on the plastic like asthenosphere. Faults are in deep underground, they are always moving slowly that we can’t even feel it. Seismologists are studying how to predict an earthquake to be safer in the earthquake by learning and studying

Understanding Volcanoes The Earth has a long history of volcanic activity. Currently, there are approximately 1,500 active volcanoes worldwide (USGS, 2014). Whether erupting on the Earth’s surface or deep in the ocean, volcanic activity can result in devastating natural disasters. A thorough background regarding volcanoes and their formation mechanisms, historical data, and damaging impact from previous eruptions is needed in order to understand the complicated science behind volcanoes. Background

the island of Iceland. Which is due to the formation of the Mid-Atlantic ridge, which is where two tectonic plates are diverging away from each other. Features Volcanoes release large amounts of energy from beneath the lithosphere, (Earth's crust and upper part of the mantle) and asthenosphere, (semi-molten mantle). During volcanic eruptions molten rock or magma rises up from the asthenosphere towards the surface as it's propelled by gases surrounding it. Some eruptions can occur through
