The Law of Inclusions basically states that any rock (or mineral or fossil) that is entirely within another rock must be older than the rock containing it. The rock containing the inclusion formed around the already existing rock, thus preserving it inside.
For example, a fossil bone found in limestone is necessarily older than the limestone surrounding it.

CoachInclusions are used in relative dating to determine the sequence of formation of rock layers. If a layer contains inclusions of another rock type, the layer must be younger than the inclusions. This is because the inclusions were already present in the older rock and got incorporated into the younger rock layer during its formation.

What is the process by which scientists match sedimentary strata to other rocks of different ages?
Its position in the stratigraphic column, particularly if there are any index fossils. if that fails, then radiometric dating techniques may be appropriate. There are a wide variety of radioisotopes to be used ranging from 14C (5700 years half life) through K-Ar, and to the various uranium series.
Principle of inclusions?
The principle of inclusions states that any rock fragment included in another rock must be older than the surrounding rock, as the inclusion had to exist before the rock containing it formed. This principle is used in relative dating to determine the sequence of events in geologic history. By examining inclusions, geologists can establish the relative ages of rock layers.
How is relative dating more accurate?
Relative dating is not more accurate than absolute dating. Relative dating will, if done properly, give you an order sequence in time but it will not return any information about when something happened unless there is other information that can be used to establish a time frame.
