These types of rocks are comprised of particles from many preexisting rocks which were transported (mostly by water) and redeposited somewhere else. Atomic mass is the heaviness of an atom when compared to hydrogen, which is assigned the value of one. In beta decay, either an electron is lost and a neutron is converted into a proton (beta minus decay) or an electron is added and a proton is converted into a neutron (beta plus decay).Types of sedimentary rocks include sandstone, shale, and limestone. In beta decay the total atomic mass does not change significantly.For example, the remaining radioactive parent material will decrease by 1/2 during the passage of each half-life (1→1/2→1/4→1/8→1/16, etc.).Half-lives as measured today are very accurate, even the extremely slow half-lives.Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline.Mike Riddle exposes the unbiblical assumptions used in these calculations The primary dating method scientists use for determining the age of the earth is radioisotope dating.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.
The dating process then requires measuring how much daughter element is in a rock sample and knowing the decay rate (i.e., how long it takes the parent element to decay into the daughter element—uranium into lead or potassium into argon). Half-life is defined as the length of time it takes half of the remaining atoms of a radioactive parent element to decay.
Therefore, there are several assumptions that must be made in radioisotope dating.
Three critical assumptions can affect the results during radioisotope dating: Radioisotope dating can be better understood using an illustration with an hourglass.
Radioisotope dating is commonly used to date igneous rocks.
These are rocks which form when hot, molten material cools and solidifies.

Scientists use observational science to measure the amount of a daughter element within a rock sample and to determine the present observable decay rate of the parent element.
