What term describes the characteristics of physical remains that are created by human behavior?

The term that best describes the characteristics of physical remains that are created by human behavior is "features." Features refer specifically to non-portable remnants created or modified by humans, such as structures, hearths, and other constructions that cannot be removed from their original location without altering their form or meaning. They provide significant insights into past human activities, cultural practices, and interactions with the environment.

Artifacts, on the other hand, are portable objects made or utilized by humans, like tools or pottery, while ecofacts refer to natural remains that provide information about past environments, such as seeds or bones, but do not directly reflect human behavior. Context, while important for understanding the relationship between artifacts, features, and ecofacts, does not describe the physical characteristics themselves. Hence, the most accurate term in this instance is features, as it encompasses those aspects of human behavior reflected in the physical landscape.
