True or False? Relative Dating determines the exact age of rock layers
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -The numerical ages of rocks in the Geologic Time Scale are determined by radiometric dating, which makes use of a process called radioactive decay – the same process that goes on inside a nuclear reactor to produce heat to make electricity. Radiometric dating works because radioactive elements decay at a known rate.

Detailed explanation-3: -What is true about relative dating? A: Relative Dating uses the half life of isotopes to get the exact age of a rock or mineral.

Detailed explanation-4: -Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e., estimated age).

Detailed explanation-5: -Relative dating is the process of determining if one rock or geologic event is older or younger than another, without knowing their specific ages-i.e., how many years ago the object was formed.
