Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
if there is movement on eithert side of the fracture, what is it?
A
strike-slip
B
crust
C
thrust fault
D
fault
Explanation: 

Detailed explanation-1: -If rocks on one side of the break shift relative to rocks on the other side, then the fracture is a fault. If there is no movement of one side relative to the other, and if there are many other fractures with the same orientation, then the fractures are called joints.

Detailed explanation-2: -Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.

Detailed explanation-3: -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. Such movement on the faults is generally a response to long-term deformation and the buildup of stress.

Detailed explanation-4: -Faults are planes of detachment resulting when rocks on either side of the displacement slip past one another. How Rocks Become Deformed. Three Types of Tectonic Forces. 1.

Detailed explanation-5: -Faults are fractures in Earth’s crust where movement has occurred.
