Where would evidence of earthquakes most often be found throughout Earth’s history?
A
In dry riverbeds
B
Along fault lines
C
Along ocean shoreline
D
In desert sand dune formations
Explanation: 

Detailed explanation-1: -Faults are fractures in Earth’s crust where movement has occurred. Sometimes faults move when energy is released from a sudden slip of the rocks on either side. Most earthquakes occur along plate boundaries, but they can also happen in the middle of plates along intraplate fault zones.

Detailed explanation-2: -The boundaries between plates contains systems of deep cracks, called faults. Most earthquakes occur along these faults.

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: -The Ring of Fire. The Circum-Pacific belt, also known as the “Ring of Fire”, is the world’s greatest volcanic and earthquake belt, where 81 percent of recorded earthquakes occur. Alpide Belt. The Mid-Atlantic Ridge. Seismically Most Active Countries.
