artistic techniques.

Explanation:

Mosaics are the images and pieces of art made out of small fragments of stone, glass, or ceramics. They are glued to the background or held together by plaster. They often decorate walls or floors and have been used since ancient times, both in secular and religious art. Frescos are wall paintings done in fresh plaster in order to make them one with the wall background. They have also been done since ancient times, and are crucial to the art of Renaissance and Orthodox Christan churches. The sculpture is the type of three-dimensional art of craving and modeling the material into the wished piece of art. It is done in various techniques and materials. It can be attached to the wall (relief) or completely free and unattached (free-standing).

Judging by all the descriptions of these three things, we can conclude that they are all different artistic techniques.
