Archaeologists studying an archaeological site use seriation to determine the relative age of each layer of objects. determine how objects were used by their owners. determine why the objects were discarded. determine the exact age of specific objects.

## Step 1<br />Seriation is a method used by archaeologists to arrange artifacts in a chronological order. This method is based on the assumption that the objects found in the lower layers of an archaeological site are older than those found in the upper layers.<br /><br />## Step 2<br />The primary purpose of seriation is to determine the relative age of each layer of objects. This is done by comparing the objects found in each layer and determining which are older and which are younger.<br /><br />## Step 3<br />The other options, such as determining how objects were used by their owners, why the objects were discarded, or determining the exact age of specific objects, are not the primary goals of seriation. These aspects are typically studied using other methods in archaeology.
