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.

WebThe Earth is made of three basic layers. The crust and the top, rigid part of the mantle. make up the lithosphere. The plastic-like layer of the mantle is called. the asthenosphere. … WebEarth's mantle is thought to be composed mainly of olivine-rich rock. It has different temperatures at different depths. The temperature is lowest immediately beneath the crust and increases with depth. The highest temperatures occur where the mantle material is in contact with the heat-producing core. This steady increase of temperature with ...
