It uses size, depth, shading, and texture
Sculpture is art that's three dimensional it is made by joining pieces of material together. Carving is an example of making a sculpture using a solid block of material like stone or wood. Another one is modeling it is a sculpture that is created by adding pliable material to create a form usually with clay or sometimes wax. And a third one is Assembly that’s where people use pre made objects or objects that are found like large pieces of metals and put them together.
I hope this helps you out :)
