Final answer:
In archaeology, ecofacts are natural items not altered by humans, artifacts are portable objects revealing human activity, and features are non-portable structures showing human modification.
Step-by-step explanation:
Archaeologists uncover materials at sites that help reveal historical and environmental contexts. These materials can be classified into several types:
- Ecofacts – Natural objects such as seeds, bone, and shells that have not been altered by humans.
- Artifacts – Portable objects like stone tools and pottery, which have been used, modified, or created by humans.
- Feature – Non-portable enhancements such as hearths or buildings, reflecting human modification of the environment.
Each category provides valuable information about the human past. Ecofacts help us understand the surrounding environment and resources that were available. Artifacts shed light on the cultural aspects such as art, tools, and technology. Features can give insight into the social organization and architectural accomplishments of the society.
