Final answer:
Fractures are separations in rock that occur without displacement of the sides. They are irregular breaks that happen along mineral planes without weak bonds.
Step-by-step explanation:
Fractures are separations or fractures in rock that occur without displacement of the sides (i.e., without faulting). These fractures are typically irregular and occur along mineral planes that do not have weak bonds. Unlike faults which involve significant movement, fractures occur due to irregular breakage in minerals.
