Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layers are?
Geologists use radiometric dating of the igneous rock units above and below the sedimentary layer to establish a time range for the sedimentary rock. They assume that the sedimentary layers are younger than the underlying igneous rock and older than the overlying igneous rock, based on the principle of superposition. This allows them to estimate the age of the sedimentary layer by determining the ages of the surrounding igneous rocks.
What are ingenue rocks the best types of rock samples for radioametric dating?
Igneous rocks are the best types of rock samples for radiometric dating because they form from the cooling and solidification of molten material, which allows for the incorporation of radioactive isotopes at the time of their formation. This provides a clear starting point for measuring the decay of these isotopes over time. The closed system nature of igneous rocks, where no parent or daughter isotopes are lost or gained after formation, enhances the accuracy of dating. Common examples used in radiometric dating include basalt and granite.
The absolute age of a rock is the approximate number of years ago that the rock formed. The absolute age of an igneous rock can best be determined by?
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layer and age .?
To date a sedimentary rock layer between two igneous rock units, geologists typically use radiometric dating on the igneous rocks above and below the sedimentary layer. They assume that the sedimentary layer was formed after the lower igneous layer and before the upper igneous layer, thus establishing a relative age. The ages obtained from the igneous rocks provide a minimum and maximum age for the sedimentary layer, allowing geologists to estimate its age within that timeframe. This technique relies on the principle of stratigraphy and the law of superposition.
Why is igneous rock best for radiometric dating?
What method, and what materials, are best for dating depends on what exactly you are after.

Radiometric dating of igneous rocks that relate to the sedimentary rock
How is the absolute age of a rock determined?
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
Why are igneous rock most often used in radiometric dating?
Their radioactive clock is set when they solidify from magma or lava.
What do Geologists use radiometric dating to date sedimentary rock?
Geologists use radiometric dating of volcanic ash layers within sedimentary rock to determine the age of the sedimentary rock. By dating the igneous rock layers above and below the sedimentary rock, geologists can establish a bracket of time within which the sedimentary rock was deposited.

The absolute age of a rock is the approximate number of years ago that the rock formed The absolute age of an igneous rock can best be determined by?
The absolute age of an igneous rock can best be determined by radiometric dating methods, such as uranium-lead dating or potassium-argon dating. These methods rely on the natural decay of radioactive isotopes in the rock to calculate the time elapsed since the rock formed.

Why is radiometric dating less useful to date sedimentary rocks than igneous rocks?
Radiometric dating is less useful for dating sedimentary rocks because they are made up of material that has been transported and deposited from other sources, making the age of the sedimentary rock different from the age of the material within it. Igneous rocks directly crystallize from magma and accurately retain the age of their formation through radiometric dating.
The absolute age of a rock is the approximate number of years ago that the rock formed. The absolute age of an igneous rock can best be determined by?
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
What can radiometric dating tell us about the age of rock that law of superposition cannot?
Radiometric dating can give us the absolute age of the rock. Trace fossils and the Law of Superposition can only provide the relative age of the rock. Radiometric dating is far more specific in formation analysis.
How old are igneous rocks?
Igneous rocks do not have a specific age. They are formed from lava or magma cooling and solidifying, which can happen at any point in time. The age of an igneous rock can be determined through radiometric dating techniques.
