What are Earthworks typically made from?

Earthworks are typically created using natural and organic materials primarily because they are often site-specific and integrated into the landscape. Artists utilize materials found in the environment, such as soil, rocks, sand, and vegetation, to create large-scale works that interact with and reflect the geographical features of the site. This use of natural materials emphasizes the connection between the artwork and the Earth, aligning with the conceptual intentions of Earthworks, which often explore themes of nature, ecology, and the relationship between humankind and the environment.

In contrast, the other options involve materials that are not characteristic of Earthworks. Metal and glass are associated with construction and sculptural works that are not site-specific. Paint and canvas are traditionally used in painting and represent a different art form altogether, while mixed media and textiles may apply to various forms of art but do not encompass the primary essence of Earthworks that focus on natural materials and their integration into the landscape.
