Explanation of Solution
Scientists measure Earth's geological and biological events using the geologic time scale, which is divided into eon, epoch, eras and periods. The Cambrian explosion 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 layers worldwide, known as the K-T boundary, might indicate that a large meteorite collided with Earth.
The theory of plate tectonics describes Earth's surface as large plates that move over Earth's thick, liquid interior. These plates are made up of various types of rocks. Paleontologists are scientists who study fossils. They determine the relative age of rocks using relative dating, which compares the sequence of rock layers. The law of superposition states that younger rock layers are deposited on top of older rock layers. Another method of determining the age of rocks is radiometric dating, which measures the decay of radioactive isotopes. The rate of decay can be measured using half-lives, the amount of time required for half of a radioactive isotope to decay.
