absolute age

• the numerical age or a rock or object

• the age of rocks and features compared with other nearby rocks and features

• a piece of an older rock that becomes part of a new rock

• the age in which rocks become sediment

uniformitarianism

• principle that states geological processes that occur today are similar to those that occurred in the past

• principle that in undisturbed rock layers, the oldest rocks are at the bottom

• principle that if one geologic feature cuts across another feature, the feature it cuts across is older

• principle that most rock forming materials are deposited in horizontal layers
