A decay in a rock refers to the process of weathering and breakdown of minerals within the rock due to various environmental factors, such as temperature changes, moisture, and chemical reactions. This can lead to the physical disintegration of the rock and the alteration of its chemical composition. Over time, decay contributes to the formation of soil and the recycling of nutrients in ecosystems.

When the hard parts of an organism decay and leave a cavity in the rock, a fossil mold can form. This mold is a negative impression of the organism's hard parts in the surrounding rock, preserving the shape and structure of the original organism.
At 0 years on a horizontal axis of a graph depicting the decay of strontium in igneous rock, the concentration of strontium-87 (the stable isotope) would represent the initial amount present in the rock. This point marks the starting measurement before any decay has occurred, establishing a baseline for subsequent measurements of strontium-87 and strontium-86 isotopes over time as radioactive parent isotopes decay into daughter isotopes.
To calculate the age of a rock using radiometric dating, scientists measure the abundance of radioactive isotopes and their stable decay products within the rock. By knowing the half-life of the radioactive isotope, which is the time it takes for half of the original isotope to decay, they can determine how many half-lives have passed since the rock formed. This information allows them to calculate the rock's age. For example, if a rock contains a certain amount of uranium-238 and its decay product, lead-206, scientists can use their respective ratios to estimate the time elapsed since the rock's formation.
It can do but not always, it usually decays into bits very like itself.
The cycle of rocks from their birth to eventual decay is termed as Rock Cycle.

Scientists use radiometric dating to determine the age of rocks by measuring the decay of radioactive isotopes in the rock. This method relies on the known rates of decay of specific isotopes to calculate the age of the rock. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, scientists can accurately determine how long ago the rock 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.

Absolute dating relies on radioactive decay of elements in a rock. When an igneous rock is formed it may contain elements that are a mixture.
They need to determine the amount of radioactive decay of a specific isotope in the rock since its formation.
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
