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
The tectonic plates are floating on top of the molten rock and moving around the planet.
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
Tectonic plates are the moving pieces under the Earth's surface that form the Earth's crust. These plates float on the semi-fluid asthenosphere and interact with each other through processes like subduction, spreading, and collision, which contribute to the shaping of Earth's surface features.
The movement of crustal plates is driven by convection currents in the mantle. As these currents circulate, they drag the overlying crustal plates with them, causing them to move. This movement can lead to various geological phenomena, such as earthquakes, volcanic eruptions, and the formation of mountain ranges.
beacause it is moving
Plate tectonics.
rocks
they just happen earthquakes are caused from the plates under earths surface moving
