GENERAL KNOWLEDGE

Detailed explanation-1: -Archaeologists can excavate ancient structures and burial sites and begin to infer how the people lived from fossils (like human remains) and artifacts (human-made items).

Detailed explanation-2: -As they walk, they look for evidence of past human activity, including walls or foundations, artifacts, or color changes in the soil that may indicate features.

Detailed explanation-3: -Very few artifacts recovered from an archeological site can be absolutely dated. Archeologists use several methods to establish absolute chronology including radiocarbon dating, obsidian hydration, thermoluminescence, dendrochronology, historical records, mean ceramic dating, and pipe stem dating.

Detailed explanation-4: -One of the best-known methods of absolute dating is called radiocarbon dating. Radiocarbon dating (often written shorthand to C-14 dating) is a method for dating sites by analyzing the amount of Carbon-14 (a radioactive isotope of carbon) found in organic remains like charcoal or bones.
