The correct answer is D. Time periods on the geologic time scale are not even in length because they are based on important events that happened in Earth's history. The geologic time scale is divided into various periods that represent significant changes or major events in Earth's development, such as mass extinctions, the diversification of life forms, or the formation of major mountain ranges. These events and changes serve as markers in Earth's history, and the time periods are named and defined according to them. The length of each time period is determined by the duration of the event or the time it takes for the significant change to occur. Therefore, the length of the time periods is not consistent and can vary depending on the significance of the event.
