Measurement

Radioactive isotopes are atoms with an unstable nucleus that emits radiation over time. The rate at which an isotope decays is constant, and this decay rate can be used to determine the age of a rock. The Larina Age is determined by measuring the amount of radioactive isotopes in rocks. The most common radioactive isotopes used for dating rocks are uranium-238, uranium-235, thorium-232, and potassium-40.

• Half-life: The half-life of a radioactive isotope is the amount of time it takes for half of the atoms in a sample to decay. The half-life of uranium-238 is 4.47 billion years, while the half-life of potassium-40 is 1.25 billion years.
• Parent and daughter isotopes: When a radioactive isotope decays, it transforms into a different element, called the daughter isotope. For example, when uranium-238 decays, it transforms into lead-206. The ratio of the parent isotope to the daughter isotope can be used to determine the age of a rock.
• Assumptions: The Larina Age assumes that the radioactive decay rate has been constant over time and that the rock has not been significantly altered since it formed.

Crust

The Larina Age is a term used to describe the age of the Earth's crust. It is determined by measuring the amount of radioactive isotopes in rocks and is expressed in billions of years. Crustal age determination is an important component of the Larina Age, as it provides a timeline for the Earth's history and allows scientists to date geological events, such as the formation of mountains and the extinction of species.

Crustal age determination is based on the principle of radioactive decay. Radioactive isotopes are atoms with an unstable nucleus that emits radiation over time.
