Why are time periods in the geologic time scale are not even in length? Responses They are based on the thickness of the Earth's rock layers. They are based on the thickness of the Earth's rock layers. They are based on a different type of calendar used to track Earth’s history. They are based on a different type of calendar used to track Earth’s history. They are based on the type of fossils found in rock layers of the Earth. They are based on the type of fossils found in rock layers of the Earth. They are based on important events happened in Earth’s history.
The time periods in the geologic time scale are not even in length because they are based on significant events in Earth's history, such as mass extinctions or major geological changes. These events do not occur at regular intervals, so the time periods are not evenly spaced. Additionally, the boundaries between time periods are often defined by changes in rock layers and the types of fossils found within them, rather than by equal time intervals.
The answer is?
The time periods in the geologic time scale are not even in length because they are based on significant events in Earth's history. These events do not occur at regular intervals, so the time periods are not evenly spaced.
