Final answer:
Archeological findings in Classical period Greece can be skewed due to preservation bias, historical bias, and geological bias.
Step-by-step explanation:
Archeological findings in Classical period Greece can be skewed due to various biases. These biases include preservation bias, where certain materials may not survive the test of time and therefore may not be discovered during excavations. Historical bias is another factor, where excavation efforts are often selective and based on priorities, leading to incomplete representation of the past. Geological bias is also a concern, as natural processes can alter or bury evidence. Therefore, it is important to consider these biases when interpreting archeological findings from Classical period Greece.
