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.
Inclusions 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.

The dating process that places geologic events in proper sequence is?
The dating process that places geologic events in proper sequence is called relative dating. Relative dating relies on the principles of superposition, original horizontality, cross-cutting relationships, and faunal succession to determine the relative ages of rock layers and fossils. It does not provide an exact age in years but helps establish a chronological order of events. Absolute dating techniques, such as radiometric dating, are used to determine the actual numerical age of a rock or fossil.

What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)

Relative dating is used to determine the?
Relative age is used to determine the age and how old a geological feature or fossil.
What is an name to describe inclusions in a diamond?
The term "diamond inclusions" refers to natural imperfections or minerals trapped inside a diamond during its formation process. These inclusions can affect the diamond's clarity and are used to help identify and grade diamonds.
Darwin would have used relative dating because?
radiation had not been discovered.

Describe two ways a paleontologist determines the approximate age of a fossil?
Paleontologists can determine the age of a fossil by using relative dating techniques, such as examining the position of the fossil in relation to surrounding rock layers, or by using absolute dating methods, such as radiometric dating to determine the actual numerical age of the fossil based on the decay of radioactive isotopes within it.
One commonly used method of relative dating is?
It's illegal, so don't do it.
