Generally, <u>deltas are structures that are formed when a body of water empties its contents into another body of water, usually a larger one.</u>
While the water goes into the larger water body, <em>the sediments being carried by the water are </em><em>deposited</em><em> at the mouth of the larger water body and an over-the-time accumulation of these sediments results in a landform known as delta.</em>
