EARTHQUAKES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why do earthquakes occur?
A
When tectonic plates build up pressure and finally release it an earthquake occurs
B
When tecctonic plates divert from each other
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.

Detailed explanation-2: -Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

Detailed explanation-3: -Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Detailed explanation-4: -It is caused by a disturbance deep inside the earth’s crust. The outer layer of the earth is fragmented. Each fragment is called a plate. Earth’s plates are in continualen these plates brush ptone another or undergo collision, causes earthquakes.

Detailed explanation-5: -While most earthquakes are caused by the slipping of tectonic plates, minor earthquakes can also be caused by volcanic eruptions, collapse of rock formations on Earth’s surface, or underground explosions.
