Detailed explanation-1: -Stick-slip refers to a movement of two sides of a fault.
Detailed explanation-2: -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-3: -Earthquakes occur when energy stored in elastically strained rocks is suddenly released. This release of energy causes intense ground shaking in the area near the source of the earthquake and sends waves of elastic energy, called seismic waves, throughout the Earth.
Detailed explanation-4: -A phenomenon, in a scientific context, is something that is observed to occur or to exist. It is simply a fact or event that can be observed with the senses, either directly or using equipment such as microscopes or telescopes. This meaning of phenomenon contrasts with the understanding of the word in general usage.
Detailed explanation-5: -The friction across the surface of the fault holds the rocks together so they do not slip immediately when pushed sideways. Eventually enough stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the rock to cause the shaking that we feel during an earthquake.
