Coastal landforms are created by a variety of natural processes involving the movement and deposition of sediment, as well as the erosive power of water and wind. Here's a step-by-step description of the formation and features of beaches, cliffs, and deltas, and the role of various erosional and depositional processes in shaping these coastal landscapes.

1. Beaches: Beaches are formed through a process called deposition, where waves carry sand and pebbles from the sea and deposit them on the shore. Over time, these materials accumulate to form a beach. The size and shape of a beach can change based on the amount of sediment available and the power of the waves. Beaches can also be shaped by wind, which can move sand inland to create dunes.

2. Cliffs: Cliffs are formed through a process called erosion, where waves crash against the shore, wearing away the land. Over time, this can create steep, vertical cliffs. The rate of cliff erosion can vary based on the hardness of the rock and the power of the waves. Soft rock, like sandstone, erodes more quickly than hard rock, like granite. Cliffs can also be shaped by weathering processes, such as freeze-thaw cycles, which can cause rocks to crack and break off.

3. Deltas: Deltas are formed at the mouth of rivers, where the river meets the sea or a lake. As the river slows down, it drops the sediment it's carrying. Over time, this sediment builds up to form a delta. The shape of a delta can vary based on the amount of sediment available and the strength of the waves and tides. Deltas can be shaped by both erosional and depositional processes.

Erosional processes, like wave action and weathering, play a key role in shaping coastal landscapes by wearing away rocks and sediment. This can create features like cliffs and sea stacks. Depositional processes, like the accumulation of sediment by rivers and waves, can create features like beaches and deltas. The balance between these processes can determine the shape and stability of a coastal landscape.
