1. Seismic Wave: It may be defined as the vibration generated by an explosion, earthquake or from some powerful energetic source within the earth’s surface. The wave travels only beneath the earth’s surface and is usually measured on a seismograph.
2. Lithosphere: It is the solid outermost part of the earth’s surface which contains a hard portion of crust and the mantle. It is also one of the coolest layers of the earth that has the ability to conduct heat.
3. Asthenosphere: It is the layer of the earth, which is beneath the lithosphere and is said to be quite hotter than any other layer. It plays a crucial role in the movement of the tectonic plates across the face of the earth’s surface.
4. Convection Current: It is defined as the movement of fluid caused by the change in temperature that transfers heat from one part of the fluid to another. It usually occurs within the plate tectonics, ocean currents, and winds.
5. Mantle: The part of the earth’s surface between the core and crust is called mantle. It is the hardest part of the earth’s interior that constitutes around 84% of the earth’s total surface.

Our plate tectonics assignment help experts cover a lot of topics such as pressure, crust, outer core, heat transfer, inner core, conduction, radiation, density, fossil, deep ocean trench, transform boundary, rift valley, fault, etc.
