some students compare four insect fossils. they want to know which of these fossils is the youngest. which of the following questions would be best for them to ask? a: which one is lightest in mass? b: which one is lightest in color? c: which one was unearthed from the richest soil? d: which one was uncovered at the most shallow depth?
Answer

In geology, generally, fossils found at shallower depths are younger as newer layers of sediment accumulate over time. Mass, color, and soil - richness do not directly correlate with the age of a fossil.
Answer:
D. Which one was uncovered at the most shallow depth?
