Why does phanerozoic eon has many more divisions and dates associated than archean eon?
The Phanerozoic Eon has many more divisions and dates associated with it than the Archean Eon primarily due to the abundance of fossil records and geological evidence available from this time, which spans the last 541 million years. The emergence of complex life forms, diverse ecosystems, and significant geological events during the Phanerozoic provide a clearer timeline for scientists to study. In contrast, the Archean Eon, which predates complex life, is characterized by simpler life forms and limited geological evidence, leading to fewer distinct divisions and less precise dating.

Why can it be difficult to assign dates to the divisions of the geologic time scale?
Assigning dates to divisions of the geologic time scale can be difficult because different rock layers and fossils may not be found in all locations, making correlation between different areas challenging. Additionally, the accuracy of dating methods can vary depending on the type of material being dated. Lastly, changes in Earth's environment and processes over time can complicate the interpretation of the geologic record.
