Q. A huge mass of ice fed by snow on a high mountain slowly sliding downhill before it starts melting is ________?
Answer: Glacier
Notes: The correct answer is "Glacier." A glacier is a large mass of ice formed from compacted snow that moves slowly down a mountain due to gravity. Glaciers can be found in polar regions and high mountain ranges, and they play a crucial role in Earth's climate system. They store about 69% of the world's freshwater and are indicators of climate change, as their retreat is often linked to rising global temperatures.
