absolute age
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.
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.
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.
Coal is a sedimentary rock that forms from the remains of plants that have been buried and compressed over millions of years.
Yes, coal is considered a type of rock. It is a sedimentary rock formed from the remains of plants that have been compressed and heated over millions of years.

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.
The land where the rock was formed was underwater when the rock was formed. Over the years layers of Sediment sank to the bottom. Pressure formed the sediments into rock.
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.
It varies with the type of rock being formed. Some igneous rock is formed in a matter of minutes; some sedimentary rock is formed in processes requiring many millions of years.
Sedimentary rock. Eg Conglomerate.
Yes it is.
Train has been a band since 1993. They have been together for 21, almost 22, years.
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.

Because rocks form and change over millions of years that is why difficult to know exactly when a rock formed.
Saybia, the Danish rock band, has been active since 1993, taking a 2 year break between 2008 and 2010. They have released 3 albums since they formed in Nyborg in '93.
