Final answer:

Sedimentary rocks are valuable for understanding past events due to their layered structure and sedimentary structures.


Explanation:

Sedimentary rocks are valuable in documenting past events due to their layered structure, which follows a specific order from oldest at the bottom to youngest on top.
