Question

what is an earthquake? how is it caused

Answer 1

Hiiiiii machiiii ✋...

➡️ Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

➡️ When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.


➡️ The boundaries between moving plates form the largest fault surfaces on Earth.
