frictional forces.
2ans) The point inside the crust where the pressure is released is called the focus . The point on the Earth's surface above the focus is called the epicentre .
Earthquake energy is released in seismic waves. ... The most severe damage caused by an earthquake will happen close to the epicentre.
3ans)Waves are created by energy passing through water, causing it to move in a circular motion. The ocean is never still. ... Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are most commonly caused by wind.
