Webasthenosphere ăsthēn´əsfēr [ key], region in the upper mantle of the earth's interior, characterized by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere. The upper part of the asthenosphere is believed to be the zone upon which the great rigid and brittle lithospheric plates of ... Web(a) An earthquake of magnitude 8.0 on the Richter scale occurs about once every year. (b) Earthquakes occur when rocks of the asthenosphere rupture along a fault. (c) The Ring of Fire describes a geological circle on Earth where earthquakes are likely to occur.

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. iowa city cupcake deliveryWebThe asthenosphere is a layer of low rigidity that separates the rigid lithosphere from the rigid mantle. Most of the Earth's volcanic and earthquake activity occurs at the edges of lithospere plates.
