How would relative dating be used to determine the age of a fossil?
 A Fossils in layers closer to Earth’s surface are older. B Fossils in deeper rock layers are older. C The age of fossils is compared using radioactive dating. D DNA is taken from fossils
Explanation:

Detailed explanation-1: -Relative age dating is used to determine whether one rock layer (or the fossils in it) are older or younger than another base on their relative position: younger rocks are positioned on top of older rocks.

Detailed explanation-2: -Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Detailed explanation-3: -Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata). Relative dating does not provide actual numerical dates for the rocks.

Detailed explanation-4: -1 Answer. Neil A. The deeper a fossil is found, the older the rock layer it is found in.

Detailed explanation-5: -Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.
