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.
Earthquakes are also caused by humans, the way trees are
cut day by day. Earth is being excavated, buildings are being prepared, due to
all this the balance of nature deteriorates, due to which we feel earthquake
tremors again and again.
