🔆Ross Ice Shelf
✅Researchers have uncovered a surprising phenomenon in Antarctica: the massive Ross Ice Shelf, roughly the size of France, lurches forward several centimetres once or twice a day.
📍Ross Ice Shelf:
✅It is the largest ice shelf of Antarctica. It is situated in the Ross Sea, extending off the continent’s coast into the ocean.
✅It is the world’s largest floating body of ice, covering approximately 487,000 square kilometres, about the size of France.
✅Only ten percent of the ice shelf is visible, with the majority hidden in several hundred metres of ice below the surface.
✅Its thickness varies significantly, ranging from about 100 meters to several hundred meters. The thickest parts are generally found where the shelf anchors against the continent.
📍Formation:
✅It is formed by the accumulation and compaction of snow, which, over time, turns into ice.
✅It is being fed a constant flow of ice from glaciers draining from both the East and West Antarctic Ice Sheets.
✅As new ice is added, existing ice is being removed through melting at the base and ice calving at the front.
✅It plays an important role in stabilising the Antarctic ice sheet, buttressing the ice that is constantly moving over the land surface.
📍Key Facts about Ross Sea:
✅It is a giant bay just 320 kms from the South Pole. The sea is remote and positioned south and slightly east of New Zealand. It is the largest polar marine ecosystem in the world. It is relatively shallow.
✅It is strongly influenced by the coastal East-Wind Drift that sets up a vast clockwise gyre accompanied by deepwater upwelling.
✅It is the first protected area in Antarctica and home to most of the world’s penguins and many species of whale. Numerous scientific research stations are located along its coasts.

🔆Bagnoregio region in news
The town of Civita di Bagnoregio (Latium Region, Central Italy) — located at the border of the ancient Volsini volcano and placed on a high tuff peak that rests on fragile clay — is an exceptional example of preserved medieval village where successive cultural layers produced a harmonious ensemble of red tiled stone masonry buildings and stone paved narrow streets, set in a dramatically fragile and unstable environment.

🔆Glacial lakes
✅Glacial lakes are bodies of water that form in depressions or basins created by the erosive action of glaciers.
✅These lakes are typically found in regions where glaciers have previously existed or are currently present.
✅Glacial lakes vary in size and shape, ranging from small ponds to large, deep bodies of water.
✅ISRO categorised glacial lakes into four broad categories based on how they were formed — moraine-dammed, ice-dammed, erosion-based, and ‘others’.
✅Glacial lakes are crucial sources of freshwater for rivers.
✅However, they also pose significant risks, specifically of Glacial Lake Outburst Floods (GLOFs).
✅GLOFs occur when glacial lakes release large volumes of meltwater due to the failure of natural dams, resulting in sudden and severe flooding downstream.
📍Mitigation of risks posed by glacial lakes
✅As per one study, lowering of the lake levels by 10 to 30 m significantly reduces the impacts on downward towns.
Although it does not completely eliminate the risks posed by a GLOM event.
✅One way to syphon off lake water is by using long High-Density Polyethylene (HDPE) pipes.
✅In 2016, members of the Sikkim State Disaster Management Authority used this method to reduce water levels in Sikkim’s South Lhonak Lake
