GEOLOGY

Detailed explanation-1: -Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.

Detailed explanation-2: -The world’s major tectonic plates. An earthquake is caused by a sudden slip on a fault. A fault is a fracture or zone of fractures between two blocks of rock. During an earthquake, the rock on one side of the fault suddenly slips with relative to the other.

Detailed explanation-3: -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-4: -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.
