Final Answer:
The process of systematically searching a geographical region for archaeological sites is commonly referred to as "surveying" or "archaeological survey."
Step-by-step explanation:
Archaeological surveying involves a methodical exploration and examination of a specific geographical area to identify, document, and record archaeological sites or artifacts present within that region. This process typically involves various techniques such as surface surveys, aerial surveys, remote sensing, and geophysical methods to systematically locate and map out potential sites of historical or cultural significance.
Archaeologists conduct surveys to gain a comprehensive understanding of the human occupation and activities across different landscapes and time periods, contributing valuable data to the study of past civilizations and cultures.
