Fjords are found in locations where current or past glaciation extended below current sea level. A fjord is formed when a glacier retreats, after carving its typical U-shaped valley, and the sea fills the resulting valley floor.

Eskers and Drumlins are classic landforms created by the depositional action of glaciers and their meltwater streams.

Mountain, Valley, Coast, and Ridge are static landforms or features, whereas a Glacier is a dynamic body of ice that causes geological change.

The Baltoro Glacier, at 63 km in length, is one of the longest glaciers outside the polar regions. It is located in the Gilgit-Baltistan region of Pakistan-administered Kashmir, and runs through part of the Karakoram mountain range.

Fiords are deep, narrow, and elongated sea or lake drains with steep land on three sides, formed by the submergence of a glaciated valley.

Hanging valleys occur when a main glacier erodes a deep valley, leaving smaller tributary valleys high above the main valley floor.

Gangotri Glacier is located in Uttarkashi District, Uttarakhand, India in a region bordering China. This glacier, one of the primary sources of the Ganges, is one of the largest in the Himalayas with an estimated volume of over 27 cubic kilometers. Around the glacier are the peaks of the Gangotri Group, including several peaks notable for extremely challenging climbing routes, such as Shivling, Thalay Sagar, Meru, and Bhagirathi III. It flows roughly northwest, originating in a cirque below Chaukhamba, the highest peak of the group.

U-shaped valley is the landform curved by the erosional work of glacier. U-shaped valley has steep valley walls with concave slope and broad and flat valley floor. The U-shaped valley is found in the cross-section of a glacial valley or glacial troughs of mountain glaciers.

When the glaciers melt or recede they deposit the rock materials brought by them in heaps of various shapes and sizes. These are known as moraines. Moraine is a ridge-like depositional feature of a glacier. They are long but narrow ridges with height more than 30m.

The moving ice mass downslope under the impact of gravity is called glacier. About 10 per cent of the earth's surface is now covered by glacier. Glacier are formed due to accumulation of ice above snow-line under extreme cold climate.
