Radiometric dating relies on three improvable assumptions, 1) It assumes to know the amounts of the decaying material present when the rocks were formed, 2) It assumes the decay rate has been constant and 3) It assumes there have been no outside influences affecting the amounts of parent and daughter particles in that rock, or in other words the rock has been completely isolated from any outside influences. | Radiometric dating relies on three improvable assumptions, 1) It assumes to know the amounts of the decaying material present when the rocks were formed, 2) It assumes the decay rate has been constant and 3) It assumes there have been no outside influences affecting the amounts of parent and daughter particles in that rock, or in other words the rock has been completely isolated from any outside influences. |
