Landscapes like the river delta above form through in which sediment is transported from other locations to create landforms like this?

Landscapes like the river delta above form through sediment deposition

Explanation:

In summary, we can confirm that the delta of a river is created by deposition and sediments, that the geological process where sediments from one region are transported from one region, through water, to another, where they accumulate over time creating new landforms. Who supplies these sediments, is the hydrographic basin that also has the function of determining the size and shape of the delta through the assigned geological material.
