The Lithosphere is made of the two types of crust, denser oceanic crust and thicker conteniental crust, plus the upper rigid part of the mantle.
The Lithosphere float on the semi-liquid Asthenosphere. The Asthenosphere moves through a process known as convection. The convection form currents moving hotter less dense mantle toward the surface where it cools becomes denser and sinks.
Another name for the asthenosphere is the ?
The Hawaiian Islands have formed as the Pacific Plate moves northwestward over a hot spot of Earth’s interior that provides magma to form several volcanos. Explain what could happen if the Pacific Plate continues to move.
The theory of plate tectonics states that Earth’s plates are always in motion. What geological evidence supports this statement?
