The ______is the name of a period of rapid change during which the ancestors of most animal groups emerged. A layer of soot found between rock layersworldwide, known as the______, might indicatethat a large meteorite collided with Earth causing the extinction of the dinosaurs.

They determine the relative ageof rocks using ______, which compares the sequence ofrock layers. The ______states that younger rocklayers are deposited on top of older rock layers. Another method ofdetermining the age of rocks is ______, whichmeasures the decay of radioactive isotopes. The rate of decay canbe measured using ______, the amount of time requiredfor half of a radioactive isotope to decay.

[1]K is the traditional abbreviation for the Cretaceous Period, and T is the abbreviation for the Tertiary Period. The boundary marks the end of the Mesozoic Era, and the beginning of the Cenozoic Era, and is associated with the Cretaceous–Tertiary extinction event, a mass extinction.
[2]It is the first period of the Paleozoic era of the Phanerozoic eon. The Cambrian takes its name from Cambria, the classical name for Wales, the area where rocks from this time period were first studied.
