Earth Art, also known as Land Art, is a movement that emerged in the 1960s and 1970s, where artists create works using natural materials found in the environment. This art form often involves large-scale installations made from earth, rocks, trees, and other organic elements, emphasizing the relationship between art and nature. Artists like Robert Smithson and Andy Goldsworthy are well-known figures in this genre. Their works are often site-specific, meaning they are designed for a particular location, and they can change over time due to natural processes. Earth Art encourages viewers to appreciate the beauty of the landscape and the transient nature of art.
