The layer below the Earth's crust is known as mantle. This consists of magma.

The Earth's crust is not a huge single piece rather it is in many pieces or fragments. The fragments are called plates.

Storms, cyclones, earthquakes and lightning are termed as natural calamities. These causes lot of damages to the properties and enviroments. Hence, they are destructive in nature.

Due to movement of Earth's plates, most of the earthquakes occur.

Earth's plates or tectonic plates are always in motion. They continuously move and sometimes collide with each other.

On 26th January, 2001, an earthquake occurred in Bhuj district of Gujarat at a very high frequency on Richter scale.

Among oxygen, carbon, aluminium and wood, aluminium is a metal while others are non-metals. Metals are good conductors of electricity.

Earthing is important to protect building from lightning. If proper earthing is not provide than it can damage building and dangerous for life also.

Copper wires allow electric current to flow without much loss of energy. Hence, copper is a good conductor of heat and electricity. This is why copper wires are used in mains cables in houses and underground. And, a thick copper strip is used for lightning conductors on tall buildings like church spires.

Earthing is the process of transferring charges to the Earth. During lightning, if earthing is not proper, we will get electrical shocks if lightning strikes.
