* Fault Zones: These are fractures in the Earth's crust where rocks have moved past each other.
* Stress Build-up: Over long periods, tectonic plates push and pull against each other, causing stress to build up in the rocks along the fault zone.
* Elastic Strain: This stress causes the rocks to deform elastically, like a stretched rubber band.
* Rupture and Release: When the stress exceeds the strength of the rocks, the fault ruptures, allowing the stored energy to be released in a sudden burst.
* Seismic Waves: This release of energy creates seismic waves that travel through the Earth and cause the ground to shake.
Think of it like this: Imagine a tightly wound spring. As you wind it tighter, you store energy in the spring. Eventually, the spring reaches its limit and snaps back, releasing all that stored energy. This is similar to what happens in an earthquake.
Therefore, earthquakes are the result of the Earth's internal forces that build up stress along fault zones, and when the stress exceeds the strength of the rocks, the energy is released in the form of seismic waves.
