Which term refers to soil that has originated from parent material brought from other regions?

The term that refers to soil originating from parent material brought from other regions is "transported soil." This type of soil forms when materials like sediments or rocks are moved from one location to another through various agents such as water, wind, or ice. As these materials are transported, they can undergo changes in composition and characteristics, ultimately leading to the development of new soil types in the areas where they settle.

In contrast, residual soil develops directly from the weathering of the underlying bedrock in the same location without significant movement. Imported soil typically refers to soil that has been brought in for specific purposes, such as landscaping or construction, but this does not necessarily mean it has formed from other regions. Depositional soil more broadly encompasses soil that has settled out of a fluid (water, air) but does not emphasize the movement from different regions in the way "transported soil" does. Hence, "transported soil" is the most accurate term in this context.
