Since the 1950s, several discoveries have led to a new understanding of how the Earth works. This includes Plate Tectonics, which explains the structure of the Earth's lithosphere (outer shell) and the forces that drive changes in its structure.

The division is based on differences in mechanical properties and in the method for the transfer of heat. The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. This division should not be confus… ctec approved providers california

"WebWhen a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt. " - Earth plate boundaries

WebWhy do so many earthquakes originate in this region? The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate. Earthquakes in these subduction zones are caused by slip between plates and rupture within plates.

WebAn earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.In California there are two … WebFeb 11, 2024 · There are two main ways Earth materials melt: 1) hot mantle rises and decompresses; and 2) water flows through hot rock. The first type of melting occurs at diverging plate boundaries (mid-ocean ridges; continental rift zones) and hotspots, where mantle beneath plates is hot but remains solid because it is under great pressure.

WebDivergent Plate Boundaries. Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the ...
