WebStudents examine seismic evidence to determine that the Earth must have a layered internal structure and to estimate the size of Earth's core. Using an inquiry approach, students are divided into two teams (theoreticians and seismologists) to test the simplest hypothesis for what is inside of Earth; that the Earth is homogeneous throughout. WebThis course discusses phase transitions in Earth's interior. Phase transitions in Earth materials at high pressures and temperatures cause the seismic discontinuities and …

One of the most significant of these boundaries is the mantle's discontinuity, which occurs between depths of approximately 410 and 660 kilometers. psychomotor ability adalahWebSeismic discontinuities aid in distinguishing divisions of the Earth into inner core, outer core, D", lower mantle, transition region, upper mantle, and crust (oceanic and continental). Lateral discontinuities also have been distinguished and mapped through seismic tomography but shall not be discussed here. hosting ssh accessWebA discontinuity at around 670 km depth is particularly distinct.
