Answer 1

Step-by-step explanation:

• Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. ... When the rocks break, the earthquake occurs.
• The two major seismic belts are the Circum-Pacific Belt, which surrounds the Pacific Ocean, and the Alpide Belt, which stretches from the Azores through the Mediterranean and Middle East to the Himalayas and Indonesia, where it joins the Circum-Pacific Belt.
• The earthquake was caused at the convergent plate boundary between the Indian plate and the Eurasian plate boundary. These pushed together and caused the earthquake
• Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere, since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.

Answer 2

The Explaination goes like this:-

Earthquakes are due to the disturbance in Tectonic plates(the plates are molten to such a high temp. that they remain in semi-solid form)

These disturbance make earth grow indeed(because these wear and tears make earth expand)

Now comming to fundamental forces:-

there are 4 types of fundamental forces that govern our know and 'beloved universe'

1)Electro-magnetic forces:- The reason you are seeing this 'article' and the reasone you are able to switch channels on you are T.V is due to electromagnetic radiation. And there interaction collectively is known as fundamental force called electro(electric forces)-magnetic(magnetic forces).

eg:Light

2)Strong-nuclear forces:- The fact that every atom's nucleus is packed densily is due to strong nuclear forces(π-measons).These intraction give a atom its know characteristic property.

3)weak-nuclear forces:-Weak here doesn't mean they are the weakest force among 4 fundamental forces(gravity is the weakest indeed).weak-nuclear forces can be seen between alpha-decay,beta-decay.When an electron interact with a nutral particle called neutrino.

4)Gravitational forces:-These are the weakest and the most common force in nature(And the reason of why you stay on ground).Actually,we don't know much about gravitation intraction and hence,belief that they are due to 'gravitons'(these particle are theoritical and yet to be proven).

So,

that's it. The 4 fundamental forces in nature

And if i would compare the magnitude of them then,

F(strong nuclear)>F(Electromagnetic)>F(weak nuclear)>F(Gravitational)

And there you go, Everything about the FORCE...
