Can the age of Earth be reliably estimated from sediment thicknesses?
A)Yes: sedimentation rates remain constant at any one locality throughout Earth's history.
B)Yes: sedimentary rocks are rarely metamorphosed or melted.
C)No: sedimentary rocks make up only a small fraction of the rocks on Earth's surface.
D)No: much of Earth's history is represented by unconformities between strata rather than the strata themselves.

While sediment thicknesses can provide some information about the age of the Earth, it is not a reliable method due to the presence of unconformities between strata. Unconformities represent gaps in the geological record where sediment was not deposited, making it difficult to determine the age of the Earth based on sediment thickness alone.
