What is the difference between relative and numerical age dating

While most properties are based on the number of protons in an element, isotopes can have subtle changes between them, including temperature fractionation and radioactivity.

An atom that has different number of neutrons but the same number of protons.

The theory that the outer layer of the Earth (the lithosphere) is broken in several plates, and these plates move relative to one another, causing the major topographic features of Earth (e.g.

Fossils found in layers that are not as old have organisms that more resemble organisms that are alive today.strata are unique to the time they lived and can be used to correlate rocks of the same age across wide geographic distribution.
