Earth`s InteriorNameProfessorDateEarth`s interiorPlanets are structured into distinct layers. The layers appear in the order of densities of the materials making up these layers. The densest materials form the innermost layers while the least dense form the outermost layer. For planet earth, these layers from the innermost to the outermost are the iron core, mantle, crust, Liquid Ocean and the atmosphere. Understanding the layered structure of the earth is not an easy thing and requires a lot of scientific techniques. Study of seismic waves produced by earthquakes, mineral physics experiments, and gravity measurements are some of the methods used to study the patterns of earth`s deep motions. Nebular debris melt and segregates into layers and this is what forms the different layers of planets.Seismic wavesThe property of the Earth`s layers includes the physical state and composition of the materials making up each of the layers as well as how stiff these materials are. Density determines the layers of the earth, the heaviest materials forms the center of the earth and the lightest ones on the outside of the earth. Geophysical techniques and the study of seismic waves have shown the earth as comprising of interacting parts. Many earthquakes are large enough that their waves can be detected and measured on the earth`s surface. What becomes more challenging is interpreting seismic waves recorded on seismographs as seismic waves do not travel on straight paths. The waves are reflected, refracted, and diffracted as they pass through the different layers of our planet. Changes in the structure of rocks makes seismic waves to be reflected off between different layers a characteristic that is especially important in the exploration for natural gas and oil. Mapping the layering of the upper crust helps identify petroleum which appears as being trapped in specific kind of geological structures. Seismic waves are also useful in identifying the boundaries between the crust, mantle, inner and outer core. Seismic waves travel faster i...
