Most of the knowledge we have about Earth’s deep interior comes from the fact that seismic waves penetrate the Earth and are recorded on the other side. Earthquake ray paths and arrival times are more complex than illustrated in the animations, because velocity in the Earth does not simply increase with depth. Velocities generally … Read more
Crust: The outer most layer or shell of the earth is known as earth’s crust. On an average it is 30km deep. It can be up to 70km under high mountains and up to 8km under ocean. It represents less than 1% of earth’s total volume and its average density is 2.7 gm/cm3. It is … Read more

Interior of the earth- composition and physical conditions Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s … Read more
