What Defines a Coastline?
A coastline is where land meets the sea or ocean. Measuring coastlines can be tricky because their lengths vary depending on the scale of measurement—smaller inlets and bays can add significant mileage when accounted for in detail. The figures in this list are based on data from the World Factbook by the CIA and other reliable geographical sources.
Why Do Coastlines Matter?
Coastlines are vital for:
✔ Biodiversity – Home to coral reefs, mangroves, and marine species.
✔ Economy – Support fishing, shipping, and tourism industries.
✔ Climate Regulation – Oceans absorb CO₂ and influence weather patterns.
✔ Human Settlement – Over 40% of the world’s population lives near coasts.
