The best option from the provided choices is:
C: In geology, both tilt and fold are deformation of rocks due to the motion of tectonic plates; however, tilts can occur anywhere in the plate, and folds only occur at fault lines.
Explanation:
- Tilts: This refers to the tilting of rock layers, which can occur anywhere in the tectonic plate due to various tectonic forces, such as sedimentation or changes in pressure.
- Folds: These are typically the result of compressional forces and occur at specific locations, often along faults or in regions where tectonic plates interact (e.g., convergent boundaries).
It's important to note, however, that folds do not only occur at fault lines but can also form in areas of significant tectonic stress. Therefore, while option C is closest, it does contain a slight simplification regarding the occurrence of folds. If the framing of the options were adjusted to allow for a more precise understanding, one could offer a more accurate distinction.
