Based on research I did, Land Soecific (Earthwork) is using the land itself to create art. This type of artwork is typically used for indoor installations but could also be used outdoors although it is not as common. A sculpture on the other hand is designed to be displayed outdoors but could be placed anywhere depending on the purchasers desires. An example of Land Art is using rocks, dirt, and natural resources to create an image. An example of a sculpture is using form or shape whether it’s figurative or abstract to make us aware of our environment and it helps us to connect with it. Hope this helps :)
