How fjords are formed (250 words)

Answer-

                Fjords are spectacular and distinctive geological features primarily found in glaciated regions. These deep, narrow inlets of the sea are shaped by a combination of glacial activity, erosion, and tectonic forces.

Fjords begin to form when glaciers advance and carve out U-shaped valleys in the surrounding land. As glaciers move downhill, they transport immense quantities of ice, sediment, and rocks. The weight and abrasive action of the ice gradually excavate the valley floor, creating a deep depression.

Simultaneously, the surrounding mountains rise due to tectonic forces, further deepening the valley. The glacial erosion exposes a classic fjord shape, characterized by steep cliffs and a flat valley floor submerged in seawater.

As the glaciers retreat, the sea fills the newly formed valley. This infusion of saltwater creates the iconic fjord environment, where freshwater from the land meets the denser seawater. The resulting stratification leads to distinct layers of water with varying salinities and temperatures.

The stunning landscapes we associate with fjords, such as towering cliffs and deep, clear waters, are the result of this intricate interplay between glacial processes and geological forces over thousands of years. Fjords are not only natural wonders but also crucial ecosystems, supporting diverse marine life in their unique, cold-water environments.
