Final answer:
Coastal landforms include beaches, cliffs, bays, and estuaries, shaped by erosional and depositional processes, as well as tectonic activity.
Step-by-step explanation:
The different landforms that can be found along coastlines include beaches, cliffs, bays, and estuaries. Beaches are sandy or pebbly shores that often represent the area where land meets sea. Cliffs are steep rock faces, also at the edge of the sea, created by erosional processes; bays are broad coastal inlets that can provide safe harbors for boats, while estuaries are where freshwater rivers meet the sea, creating a unique brackish water habitat with a variety of wildlife.
The physical processes that cause the development of these landforms involve a combination of erosional and depositional activities. Waves and currents shape the coastline by eroding rock and depositing sediments, creating diverse landscapes that change over time. Factors like tectonic activity can also play a significant role in the formation of coastal features.
