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.
The number of years since a rock formed?
To determine the age of a rock, geologists typically use radiometric dating techniques that analyze the decay of radioactive isotopes within the rock. By comparing the ratio of parent to daughter isotopes present in the rock, scientists can calculate its approximate age. Different isotopes have different half-lives, which allow for dating rocks of varying ages.
What is the rock formed as a result of deposits from weathering and erosion?
Sedimentary rock is the rock formed as a result of deposits from weathering and erosion. Sedimentary rock can be millions of years old.
What type of rock is coal and how is it formed?
Coal is a sedimentary rock that forms from the remains of plants that have been buried and compressed over millions of years.
Is coal considered a type of rock?
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.
What is the number of years that have passed sice a rock was formed?
To determine the number of years that have passed since a rock was formed, one would need to know the specific age of the rock. This age can often be estimated using radiometric dating techniques, which measure the decay of isotopes within the rock. For example, if a rock is determined to be 100 million years old, then 100 million years have passed since its formation. Without knowing the specific age of the rock in question, it is impossible to provide an exact number of years.
What age of a rock is its age in 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.
How do layers in sedimentry rocks form?
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 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.
How long does it take to form a rock?
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.
How long has train been a band for?
Train has been a band since 1993. They have been together for 21, almost 22, years.
What rock is formed over millions of years from sediments?
Sedimentary rock. Eg Conglomerate.
Is it possible to have a rock been around since the earth formed?
Yes it is.
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.
The number of years since a rock formed?
To determine the age of a rock, geologists typically use radiometric dating techniques that analyze the decay of radioactive isotopes within the rock. By comparing the ratio of parent to daughter isotopes present in the rock, scientists can calculate its approximate age.

What is a rock formed millions of years ago called?
its called a bobshed
Why is it often difficult to know exactly when a rock formed?
Because rocks form and change over millions of years that is why difficult to know exactly when a rock formed.
