Question

Which of the following is usually most helpful in determining the age of these fossils?

A. The size of the fossils
B. The color of the fossils
C. The amount of surface area of the rock layer in which the fossils are found
D. The depth of the rock layer in which the fossils are found

Answer 1

The depth of the rock layer in which the fossils are found is most helpful in determining the relative age of the fossils, as deeper layers are generally older.

Step-by-step explanation:

The age of fossils is usually determined by looking at the depth of the rock layer in which the fossils are found. Rock layers are formed sequentially, with newer layers being deposited on top of older ones. The deepest rock layers are typically the oldest, and so the fossils found within those layers are usually older than those found in higher layers. This method of dating is part of relative dating techniques, which allow paleontologists to establish a sequence of events and the relative age of rocks and fossils without determining the exact age in years.

Answer 2

D. The depth of the rock layer in which the fossils are found

Step-by-step explanation:

Size is irrelevant because a t-rex and ancient hamsters lived together

Color is irrelevant, because with time, almost all fossils are a grey tone look

D.) is the better answer between C.) & D.) because layers of the earth are used in the approximation of the time period in which the dinosaur lived
