Fjords are formed by glaciers carving out valleys during the ice age, and then being flooded by seawater as sea levels rose. They are characterized by their narrow, deep, and steep-sided inlets, with often dramatic cliff faces on either side.
Some famous examples of fjords include:
* The Norwegian Fjords: These are some of the most well-known fjords in the world, known for their scenic beauty and dramatic landscapes.
* The Milford Sound in New Zealand: This is a stunning fjord with towering cliffs, cascading waterfalls, and abundant wildlife.
* The Kenai Fjords National Park in Alaska: This park features dramatic fjords, glaciers, and abundant wildlife.
