Stress in the earth’s outer layer cause a pushing effect against the sides of the fault. Due to this motion, rocks slip or collide against each other releasing energy. This released energy travels in waves through the earth’s crust and caus...

This energy is released in the form of vibrations called 'seismic waves'. These waves travel along the surface and through the earth at varying speeds depending on the material through which they move. It is actually these seismic waves that cause most of the destructive effects, which we associate with earthquakes.

Forces causing earthquakes were not close to the earthquake source but very distant. these distant forces cause a gradual build up of stress in the earth over tens or hundreds or thousands of years, slowly distorting the earth underneath ou...

Earth quakes happen when two giant rocks under the earth's surface, called plates, scrape against each other. This causes the earth to rumble and shake, which can knock down buildings, homes, crush cars, and do many other terrible things to...

Earthquakes question: What are the possible causes of earthquakes? Earthquakes may be caused by moving plate boundaries. It is when there are convergent, divergent or transform plate boundaries. In a convergent ... The water travelling at fast speeds will start to form great waves when the seafloor gets shallower. It may be...

Earthquakes are caused by movement of faults --by the fault breaking and the two sides moving in opposite directions. ... Between earthquakes, energy is stored in the rock as it is in a spring: by elastically deforming (bending) the rock. ... The faults that form here are normal faults.

Earthquakes are caused by the movements of giant tectonic plates that form the Earthʼs crust. Most quakes occur at the boundaries where plates meet. ... Scientist believe slow-churning convection currents in the mantle cause the plates to move.
