WORLD HISTORY

Detailed explanation-1: -Archaeologists work in teams as they excavate. They carefully remove soil layers at old sites to recover artifacts (things made and used by people). As they dig, they make notes about the contexts in which artifacts are found.

Detailed explanation-2: -In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or “dig” is the area being studied. These locations range from one to several areas at a time during a project and can be conducted over a few weeks to several years.

Detailed explanation-3: -Archaeologists wash, sort, catalog, and store recovered artifacts after bringing them back from the field. They analyze individual artifacts, but also may sort them into groups to see patterns. For example, they might weigh all the oyster shells together or count all the nails and consider them as one unit.

Detailed explanation-4: -Archaeologists have found sites through examination of air photos, various kinds of radar, including ground penetrating radar, and other indirect methods. Remote sensing techniques work best on sites that have features such as walls or deep pits that are distinctly different from the surrounding soil.

Detailed explanation-5: -Archaeologists study past human activity by excavating, dating and interpreting objects and sites of historical interest. They implement excavation projects, informally known as digs, preserve archaelogical remains and collect data that informs their understanding of the past.
