Answer :
Final answer:
The geological principles of superposition, lateral continuity, and unconformities help determine rock ages and understand rock formations.
Explanation:
The principle of superposition states that sedimentary layers are deposited in sequence, with the oldest at the bottom and youngest at the top. This law helps in determining the relative ages of rocks, where the lower layers are older than the upper ones.
The principle of lateral continuity states that layers of sedimentary rock are continuous, and interruptions occurred after the rock formation. It is useful in understanding the extent of rock layers.
The principle of unconformities refers to gaps in the rock record, indicating periods where erosion or non-deposition occurred. These provide critical insights into the geological history of an area.
