Tectonic plates.
earthquakes
That theory relates to Plate Tectonics.
Lower mantle is the surface on which the lithospheric plates move around earths surface.
Tectonic Plates
tectonics
They are geologic features because when the crustal plates move its makes cracks on earth the the mountains are one because everytime the crustal plates move it breaks the earths surface and the dirt and rocks start gathering together
Lithospheric plates are a number of rigid but moving pieces of earths surface.
the moving of the plates under the earths surface
plate tectonics are moving plates under the earths surface
Their evidence comes from rocks at earths surface.
moving tectonic plates on earths surface
The answer is tectonic plates floating on the lithosphere. Does that answer your question? LOL :)
When the crustal plate moves it vibrates the earths crust and its plates. When the crust and plates are forced to move it can result in volcanic action.
beacause it is moving
Plate tectonics.
rocks
they just happen earthquakes are caused from the plates under earths surface moving
