Answer:
Glaciation has carved out narrow sea inlets between rocky cliffs in Scandinavia and on Norway’s coasts. These inlets are called fjords.
Fjord is a landform that is a deep, narrow and elongated sea or lake with steep land on three sides. The opening to the sea is called the mouth of the fjord and is often shallow. The innermost part of the fjord is called the fjord bottom. If the oat is wider than it is long, it is a bay.
Most of the fjords are of tectonic origin and arose when there was a sharp and sudden change in the direction of movement of the tectonic plates. As a result of this, at the edges of plates already compressed by preliminary oncoming motion, numerous cracks and faults form, which are filled with sea water. In this case, the fjord can have a significant depth, up to 800 or more meters, and sometimes more than a kilometer.
