What is an earthquake?   

 

Earthquake in simple language means - Earth's vibration. Earthquake is called shaking of the earth's surface. It generates energy waves in the Earth's lithosphere, which spread in all directions and cause earthquakes.

 

Why do earthquakes happen?

The Earth is situated on tectonic plates and beneath it is liquid lava. The plates collide with each other, due to repeated collisions, the corners of the plates get muddled. Plates break due to high pressure, due to breaking, the energy released from below finds a way out towards the outside, due to which earthquake occurs.
