In India's mountain regions glaciers become sources of what?

Correct answer: Rivers

The direct answer is A: rivers. In high mountain regions, glaciers are large bodies of ice formed from accumulated snow. During warmer periods, melting glacier ice releases water. This meltwater joins streams and becomes an important source of many rivers, especially in the Himalayas. Step by step: snow falls and accumulates; pressure turns old snow into ice; the glacier stores freshwater; melting produces streams; streams join to form or feed rivers. Option A is correct. Option B, sand dunes, are heaps or ridges of wind-blown sand, usually associated with deserts, not glacier melt. Option C, corals, are marine organisms or limestone structures found mainly in warm, shallow seas; glaciers do not become corals. Option D, salt flats, form where salty water evaporates in dry basins; they are not the normal result of glacier melt. The memory cue is “Himalayan glaciers feed Himalayan rivers.” Glaciers may not be the only sources of every river, because rain and groundwater also contribute, but they are crucial sources of many mountain rivers.
