Since, in seismic zones, all the houses and buildings should be designed and constructed in such a way, so that they can withstand major earthquake tremors.

Three precautions during earthquake inside the house are as follows:
(i) Instead of running away, we should get under a desk, table or bench or sit against a nearby interior wall.
(ii) Pick a safe place where things will not fall on you, away from windows, bookcases or tall heavy furniture.
(iii) Wait at your safe place until the shaking stops.

The causes of sparking are given below:
(i) Shaking of wires and blowing of winds.
(ii) Looseness of plug in its socket.
(iii) Electric poles consisting of loose wires.

Lightning conductor is connected with a wire which is finally connected to a copper plate and copper plate is grounded. So, when lightning occurs, all the charge is transferred through this conductor and reach to the ground and building gets no harm.

Since, both the balloons acquire the same charges when being charged upon rubbing. Thus, repel each other.
On the other hand, one charged and the other uncharged balloon attract each other. This is due to the property of charges that unlike charges attract each other. The uncharged balloon having opposite charge is attracted by the other charged balloon.

Lightning conductor is a device which is used to protect the buildings from the effect of lightning.

The tremors produce waves on the surface of the earth. These waves are called seismic waves.

In order to protect us from electrical shock due to leakage of electric current, the earthing is provided in the building.

Unlike charges attract each other whereas like charges repel each other.

As we know that earthquakes are usually caused by the movement of plates on the outer layer of earth. So, the regions which fall on the boundaries of these plates are called danger zones. In India, the most dangerous zones which are prone to earthquakes are Kashmir, western and central himalays, the whole of North-East, Rann of Kutch, Rajasthan and the Indo-Gangetic planes.

(a) A sudden shaking of the earth which last for very short time is called an earthquake.
(b) Quake-resist building means that the buildings should be constructed in such a way so that it can withstand for more time even on shaking the earth.
(c) Since the viscous force of water resists the oscillation or vibration of building caused by shaking of the earth and ultimately reduces the shaking in building with hose.
(d) They use applications of science and technology and more curious with the methods.

Clouds having water droplets, coming from different directions, strike each other and due to striking, a friction force is created when they rub each other and during rubbing, the charges appear on clouds (static charges).
They grow up due to continuous charging and finally discharge when any moisture place is found on the earth because they get the path due to this place.

Since the process of electric discharge always occurs between the earth and the clouds, it ultimately leads to the lightning.
