What drives plate tectonics?
What drives plate tectonics?
The movement of the Earth's lithospheric plates is driven by the heat-powered currents within the mantle.
What are L-waves?
What are L-waves?
Seismic waves are vibrations that travel through the Earth. L-waves are not a type of seismic wave. There are P-waves, S-waves, and surface waves.
