Understanding Geologic Time

The video tutorial explains how geologists measure the age of Earth using geologic time, which is divided into relative and absolute time. Relative time involves comparing the age of rocks and events, while absolute time provides specific ages in years. The law of superposition helps determine the relative age of rock layers. Modern techniques allow geologists to accurately date rocks and fossils, providing absolute ages. Examples include dating a cinder cone volcano and fossilized trees.
