 A delta is defined as a triangular mass of sediment, silt, and sand, deposited at the mouth of a river. Deltas form when a river flows into a body of standing water, such as a sea or lake, and deposits large quantities of sediment. They are usually crossed by numerous streams and channels and have exposed as well as submerged areas. Which process was primarily responsible for the formation of a delta?

Below is a diagram of the transformation of sediment to magma.

Sediment ----?---> Limestone ----?----> Marble ----?----> Magma
