The process by which rocks are broken down and not transported is termed

The correct answer is "weathering". Weathering is the process by which rocks are broken down into smaller fragments or particles through physical, chemical, and biological means. These broken-down rock particles remain in place and do not get transported away. Weathering can occur through a variety of mechanisms including freeze-thaw cycles, chemical reactions, and plant root growth. It is an important process in the formation of soil and can also lead to the development of unique landforms.
