In the context of geology, a theory which explains the spread of energy throughout an earthquake is known as the elastic rebound theory. As reefs on opposing sides of a fault become subject to force and shift, they gain energy and gradually deface until their innate force is passed. In this way, the elastic rebound is comparable to what happens when we release a stretched rubber band.
The Cinder cones are the volcanic landform that develops from felsic lava oozing out of the ground—often in the crater of another volcano. It is made from discharged lava fragments that harden in flight to produce scoria or vesicular rock.
