What are the three characteristics of coastline?

Coastlines are dynamic systems that are constantly changing in response to a variety of forces, including waves, tides, currents, and sea level rise. They are also influenced by human activities, such as coastal development and pollution. Here are three general characteristics of coastlines:

Irregularity: Coastlines are rarely straight. They are typically irregular, with bays, headlands, and peninsulas. This irregularity is the result of erosion, deposition, and tectonic activity.

Diversity: Coastlines vary greatly in their physical characteristics, from rocky cliffs to sandy beaches to mangrove swamps. This diversity is due to differences in geology, climate, and other factors.

Vulnerability: Coastlines are vulnerable to a variety of hazards, including storms, flooding, sea level rise, and erosion. These hazards can damage coastal ecosystems, infrastructure, and communities.
