Absolute Age
The age of a rock is typically measured in years using radiometric dating techniques. These techniques analyze the decay of radioactive isotopes in the rock to determine the amount of time that has passed since the rock formed.
True. Numerical age is the age of a rock or geological feature in years, typically determined through radiometric dating methods.
Uranium-238 (U-238) is an appropriate radioactive isotope to estimate the age of a rock formation believed to be a billion years old. This isotope has a half-life of about 4.5 billion years, making it suitable for dating rocks of such age. By measuring the ratio of U-238 to its decay product, lead-206 (Pb-206), scientists can calculate the age of the rock formation.
The actual age of a rock can be determined through radiometric dating methods that analyze the decay of radioactive elements within the rock. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the rock's age in years.
Schist rock is a type of metamorphic rock that forms deep within the Earth's crust. The age of schist rock can vary widely, as it depends on when the rock was formed through the process of metamorphism. In general, schist rock can range in age from hundreds of millions to billions of years old.

Needle cricothyroidotomy is the only form of this procedure that can be done in children under 12 years of age.
The Rock is 37 years old.
The age in years of a rock or other object is a representation of the time that has passed since its formation. This age can be determined through various methods such as radiometric dating or relative dating techniques.
relative age
depends on the kind of rock the material it is made of.
