With its focus on the ancient past, archaeology somewhat resembles paleontologythe study of fossils of long-extinct animals, such as dinosaurs.
However, archaeology is distinct from paleontology and studies only past human life.
Archaeology also examines many of the same topics explored by historians.
But unlike historythe study of written records such as government archives, personal correspondence, and business documentsmost of the information gathered in archaeology comes from the study of objects lying on or under the ground Archaeologists refer to the vast store of information about the human past as the archaeological record.
Two broad categories of classification methods are relative dating and absolute dating.
Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.
These remains include the fossils (preserved bones) of humans, food remains, the ruins of buildings, and human artifactsitems such as tools, pottery, and jewelry.
From their studies, archaeologists attempt to reconstruct past ways of life.
The machine is a closed re-circulated system in which water is mechanically pumped through an agitator within a tank.The agitation separates lighter residue from the sample.This light residue (flot) is collected in the small mesh bag at front.As the name implies, relative dating can tell which of the two artifacts is older.This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
