WebEarthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake. Such movement on the faults is generally a response to long-term deformation and the buildup of stress. WebHow is the asthenosphere different from the mesosphere? Physical behavior; the asthenosphere is slightly mushy where the mesosphere is solid. What happened to Earth's structure when it melted? Chemical differentiation occurred, which formed the dense iron core, and the lighter more silica and aluminum rich crust.
Web31 mrt. 2024 · Plate movement is possible because the lithosphere-asthenosphere boundary is a zone of detachment. As the lithospheric plates move across Earth’s surface, driven by forces as yet not fully understood, they interact along their boundaries, diverging, converging, or slipping past each other.
