THE LAYERS OF THE EARTH

THE LAYERS OF THE EARTH. (PLATE BOUNDARIES). What is the use of locating seismic discontinuities? Locating these disturbances enable scientists to map the inner regions of the Earth. This science, known as tomography originates from the knowledge gained from discontinuities.

Chemical and Clapeyron-induced buoyancy at the 660 km discontinuity

Chemical and Clapeyron-induced buoyancy at the 660 km discontinuity. D.J. Weidner & Y. Wang 1998. Introduction. The degree to which 660 helps or hinders whole mantle convection is a function of density contrasts derived from chemical and/or structural changes in the mineral assemblage

Causes of Plate Movement

Causes of Plate Movement. How do we know that plates move?. We know that the plates are moving because of earthquakes and volcanoes. . To understand plate movement you must remember the structure inside the Earth . Notice that the mantle is broken into the upper and lower mantle.
