Earthquake➫ Any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks.

♦ Earthquakes can be extremely violent or so slight that they only register on instruments.

♦ The largest fault surfaces on Earth are formed due to boundaries between moving plates.

♦ They are caused by sudden movements of the Earth's tectonic plates.

♦ The sudden release of tension in the tectonic plates sends waves of energy that travel through the Earth.

Answer 2

$\bf \huge \underline{\underline{Answer}}$

Seismic waves are produced when some form of energy stored in Earth's crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.” Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another.
