* Glacial Erosion: Fjords are formed by the erosive power of glaciers. As glaciers move across the landscape, they carve out deep, U-shaped valleys.

* Sea Level Rise: After the glaciers retreat, the sea level rises and floods these valleys, creating the characteristic narrow, deep inlets with steep sides that we recognize as fjords.

Deposition does play a role in the formation of features within fjords, but it is not the primary process that creates them.

Here's how deposition is involved:

* Moraine Formation: Glaciers deposit sediment called moraine at the end of their tongues. These moraines can create islands and shoals within fjords.

* Delta Formation: Rivers that flow into fjords can deposit sediment, forming deltas at the fjord mouth.

In summary: While deposition plays a part in shaping the internal features of fjords, the primary process responsible for their creation is glacial erosion.
