Which dating technique would be best for a volcanic rock containing uranium?
Radiometric dating based on the decay of the uranium.
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.
How would you calculate the age of a volcano?
Scientists usually find the age of volcanoes through radiometric dating of their rocks.
Why not use igneous rocks with relative dating?
Igneous rock is formed by lava. A fossil can't be contained in lava because it would be destroyed. So, no fossil is near lava so igneous rock can't be used for relative dating.
How would you find the age of a fossil?
You can use relative dating which is looking at the rocks around it, or you can use radiometric dating, which compares the amount of radioactive element with the amount of nonradioactive element in the rock.

Radiometric dating based on the decay of the uranium.
What types of rocks are used in radiometric dating?
From a granite, a common mineral used for radiometric dating is the biotite mica component. For this mineral is among the last to form - as it forms at the lowest temperature compared to the other components of granite.This mineral contains potassium, 40K, which may be dated by the Potassium-Argon method. By radioactive decay, a small portion of the 40K decays to Argon. (The remainder of the potassium decays to a Calcium.)This Ar component is held in the mineral crystal, and by measuring the quantities of K and Ar, the age of the biotite is determined. [to an accuracy of about 1%.] For none of the Ar would be entrained in the previous molten state.All the K in your body is also susceptible to this decay!
If I wanted to know how old a fossil was which type of dating would I be using?
Radiometric is the type of dating used to determine how old a fossil is.
Can all radioactive isotopes be used in radiometric dating?
No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappear before any useful period of time passed.

Which radiometric dating method would be ujsed to date objects found at effigy mounds?
Carbon-14

Which radiometric-dating method would be most apprioate for dating artifacts found at effi gy mounds?
Carbon-14 dating would be the most appropriate radiometric dating method for dating artifacts found at effigy mounds. This method is commonly used for dating organic materials such as wood, charcoal, or bone, which are typically found in archaeological sites like effigy mounds.
How would you find the age of a fossil?
You can use relative dating which is looking at the rocks around it, or you can use radiometric dating, which compares the amount of radioactive element with the amount of nonradioactive element in the rock.
What evidence would a scientist use to determine the absolute age of a fossil found in a sedimentary rock?
Uranium is the element that decays at a rate that relates to the sample. Uranium is the element that decays at a rate that relates to the sample.
How would a scientist determine the age of a fossilized dinosaur egg?
That can be deduced from the geological layer in which it is found; or (probably more accurate), radiometric dating can be used.
