Deltaic systems are dynamic interfaces where fluvial sediment delivery, coastal processes and chemical weathering converge to shape landforms, influence carbon cycling and regulate coastal ecology.

Explanation: Weathering is gradual disintegration of rocks by atmospheric forces, erosion is active wearing away of earth surfaces, Transportation is removal of eroded debris to new positions; ...

Processes called erosion, mass movement and weathering break down and remove material from the coast. The material is moved along the coastline by the sea and deposited when there is energy loss.
