Which of the following elements' isotopic ratios are used to make absolute determinations of the time of formation of materials?
Uranium and thorium isotopic ratios are commonly used in radiometric dating to determine the age of materials, such as rocks or minerals. By measuring the ratios of parent and daughter isotopes in these elements, scientists can calculate the absolute age of the material based on the known decay rates of these isotopes.
What elements are used to make absolute determinations of the time of formation of materials?
Radiometric dating methods such as carbon-14 dating, potassium-argon dating, and uranium-lead dating are commonly used to determine the age of materials. These methods rely on the decay of radioactive isotopes within a sample to calculate its age. By comparing the ratio of parent isotopes to daughter isotopes in a sample, scientists can estimate the time of its formation.
The number of years since a rock has formed?
The number of years since a rock has formed is determined by using radiometric dating techniques to measure the decay of radioactive isotopes within the rock. By measuring the ratio of parent isotopes to daughter isotopes, scientists can determine the rock's age. This process involves comparing the rock's isotopic composition to known decay rates and constants to calculate the time elapsed since the rock's formation.
How can the absolute age of a rock be determined?
The absolute age of a rock can be determined through radiometric dating methods, such as carbon dating or uranium-lead dating. These methods rely on the known rates of decay of radioactive isotopes within the rock to calculate how long it has been since the rock formed. By measuring the ratios of parent and daughter isotopes, scientists can determine the rock's absolute age.
What is one drawback of absolute dating?
One drawback of absolute dating methods is that they can be costly and time-consuming to perform, often requiring specialized equipment and expertise. Additionally, some absolute dating techniques are limited in their applicability to certain types of materials or time ranges.

What type of dating involves half-lives and can tell in which geologic period a rock was formed?
This is called absolute, isotopic, or radiometric dating.
Method used to estimate the absolute age of a stream is to?
The absolute age of a stream can be estimated using radiometric dating of rocks found along its path. By analyzing the isotopic composition of these rocks, scientists can determine when they formed and thereby establish the age of the stream. This method allows for accurate dating of the stream's formation based on the age of the rocks in its vicinity.
