The process in which rocks change shape is called deformation.

Here's why:

* Deformation refers to the changes in the shape or volume of a rock due to stress. This stress can be caused by forces like tectonic plate movement, pressure from buried rocks, or even the weight of glaciers.

* Deposition is the process of sediments settling and accumulating.

* Composition refers to the mineral makeup of a rock.

* Flotation is a separation process used in mining, not related to rock shape changes.
