Name one feature formed by river deposition and explain, with the aid of a labelled diagram, how it was formed. - Junior Cycle Geography - Question 1B - 2019

A delta is formed through the process of sediment deposition. As the river flows towards the mouth, it loses energy upon meeting the still water of the ocean or lake, allowing sediments to settle out of the water. Over time, these sediments accumulate, creating new land that extends out into the body of water.

The process involves several steps:

1. Erosion: The river erodes the landscape upstream, transporting sediments downstream.
2. Deposition: Upon reaching slower-moving water, the river's velocity decreases, which results in sediment being deposited.
3. Formation: Continuous deposition leads to the gradual formation of the delta as more sediments pile up.

The accompanying diagram should illustrate the flow of the river, the area of deposition, and the distinct shape of the delta protruding into the ocean/lake.

A labelled diagram depicting the river flowing into a sea/lake, with arrows indicating water flow and sediment deposition, alongside labels for the river, delta, and body of water.
