Answer:
1) When we push two books towards each other, the two books will move on top of each other, or their papers will go on top of each other.
2) I observed since books are flexible, they move on the top of other book without distorting their shape. In real life on the upper surface of earth Crustal Plate(Tectonic plate) lies. When the plates collide with each other one plates move on the top other plate and we experience shock, which is nothing but earthquake.
If there is an earthquake, the first thing to do is to go to the open ground.Will not stay in homes at all, there may be a possibility of loss of life and property by being buried in debris during earthquake. and hold on to a strong pole.
