fjord

n. narrow inlet of the sea bordered by steep cliffs, fiord

A fjord (or fiord) is a long, narrow estuary with steep sides, made when a glacial valley is filled by rising sea water levels. The seeds of a fjord are laid when a glacier cuts a U-shaped valley through abrasion of the surrounding bedrock by the rocks and sediment it carries. Many such valleys were formed during recent ice ages when the sea was at a much lower level than it is today. At the end of such a period, the climate warms up again and glaciers retreat. Sea level rises due to an influx of water from melting ice sheets and glaciers around the world (it rose over 100 m after the last ice age), inundating the vacated valleys with seawater to form fjords.
