Question
Which of the following are examples of sedimentary structures?Multiple select question.BeddingRecumbent foldsGraded bedsTurbidity currentsFaultsCross-beddingMud cracks
Solution
The examples of sedimentary structures from the options provided are:
- Bedding
- Graded beds
- Cross-bedding
- Mud cracks
Recumbent folds, turbidity currents, and faults are not considered sedimentary structures. Recumbent folds are a type of fold that is overturned to such an extent that the limbs are essentially horizontal. Turbidity currents are a type of underwater current that is driven by the high density and sediment concentration. Faults are fractures in the Earth's crust where blocks of the crust slide relative to one another. They are not formed by the process of sedimentation, hence they are not sedimentary structures.
