The correct answer is:
They are based on important events that happened in Earth’s history.
Explanation:
The 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. These events can include major changes in the Earth's climate, the evolution of new species, or the occurrence of significant geological events such as volcanic eruptions or meteorite impacts. Therefore, the length of each time period is determined by the significance and duration of these events rather than by an evenly divided time scale.
