How are the fjords formed? Why do they constitute some of the most picturesque areas of the world?
Introduction
Fjords are long, narrow, deep inlets of the sea, typically U-shaped, with steep sides or cliffs, created by glacial erosion.
Body
Formation of Fjords
During ice ages, massive glaciers flowed through existing river valleys, carving them deeper and wider into characteristic U-shaped troughs. As glaciers retreated, these deeply eroded valleys were subsequently flooded by rising sea levels, creating the distinctive marine inlets.
Reasons for their Picturesque Nature
Fjords are picturesque due to their dramatic landscapes. Towering, steep cliffs plunge into deep, calm blue waters, often adorned with numerous waterfalls cascading from 'hanging valleys'. The striking contrast between sheer rock faces, lush vegetation, and reflective water creates stunning visual appeal. Their remote, pristine nature further enhances their grandeur and attracts tourism.

Key points
Fjords are long, narrow, deep inlets of the sea, typically U-shaped, with steep sides or cliffs, created by glacial erosion.
Formation involves glaciers carving deep valleys (U-shaped) through existing river valleys during ice ages.
As glaciers retreated, these valleys were flooded by rising sea levels, creating the characteristic inlets.
Their picturesque nature stems from dramatic landscapes: steep, towering cliffs, deep blue waters, and often numerous waterfalls from 'hanging valleys'.
The contrast between the sheer rock faces, lush vegetation, and calm, reflective water creates stunning visual appeal.
Often remote and pristine, they offer a sense of untouched wilderness and grandeur, attracting tourism.
Common mistakes
Confusing fjords with other coastal features like rias or estuaries.
Incomplete explanation of formation, omitting either glacial erosion or sea-level rise.
Generic descriptions of 'beauty' without linking it to specific geographical features of fjords.
Not adequately addressing both parts of the question (formation and picturesque nature).
Difficulty: Medium — Requires specific knowledge of geomorphological processes (glacial erosion, sea-level changes) and the ability to articulate how these features contribute to aesthetic appeal. The two-part nature demands comprehensive coverage within the word limit.
