Step-by-step explanation:
Carving is a subtractive process used in sculpting, where the artist removes material to create the desired form. During carving, the original material is cut or scraped away, making it nearly impossible to create a sculpture from scratch, add more material, change the shape of the original material, or use a different type of material. Examples of carving can be found in sculptures made from wood, stone, clay, bone, ivory, and other suitable materials, with different civilizations developing unique tools depending on the available resources.
