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.

What are two methods geologist use to determine the age of a rock?

Geologists use relative dating methods to determine the sequence of events that led to the formation of rocks by analyzing the layering of rocks. They also use absolute dating methods such as radiometric dating to determine the numerical age of rocks by measuring the decay of radioactive isotopes within them.

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 do geologists use to determine the relative ages of a rock?

Relative dating refers to the process of determining the age of a rock, feature, or fossil by comparing it to the rocks around it. To use relative dating, you need to look at the order each rock layer was deposited.


Why cant geologist use the carbon-14 method to date igneous rock?

Geologists cannot use the carbon-14 method to date igneous rock because carbon-14 dating is effective only for organic materials, such as wood or bone, that contain carbon. Igneous rocks, formed from the cooling and solidification of magma or lava, do not contain organic carbon and therefore do not incorporate carbon-14 during their formation. Instead, geologists typically use radiometric dating methods involving isotopes of elements like uranium or potassium, which are suitable for dating the age of igneous rocks.


Why can't geologist use the carbon-14 method to date igneous rocks?

Igneous rocks do not contain much carbon.


How do scientist determine the ages of rocks?

They can use either radiometric dating or magnetostratigraphy.

What are the terms felsic and mafic used by geologists to describe?

Geologists use the terms felsic and mafic to describe the compositions of igneous rocks. Felsic rocks are rich in silicon and aluminum, making them lighter in color and less dense. Mafic rocks are richer in magnesium and iron, making them darker in color and denser.


Who uses igneous rocks why?

Igneous rock can be used for making weapons. Blacksmiths can use them.
