Glaciers

Glaciers are huge, slow-moving masses of ice formed from snow that has accumulated over many years.

  1. They are found mainly in very cold regions such as the polar areas and high mountains (like the Himalayas).
  2. When snow does not melt completely, it compresses into ice and forms a glacier.
  3. Glaciers store most of the Earth’s freshwater.
  4. As glaciers slowly melt, they provide water to rivers, especially during summer.
  5. Many important rivers, such as the Ganga, Indus, and Brahmaputra, originate from glaciers.
  6. Glaciers move very slowly, shaping the land by erosion.
  7. Global warming causes glaciers to melt faster, which can lead to floods and sea-level rise.

Glaciers are natural freshwater reservoirs and are very important for life on Earth.

Earth’s Freshwater

Only about 3% of all the water on Earth is freshwater.  The remaining 97% is saltwater, found in oceans and seas. Even within this 3% freshwater: A large portion is frozen in glaciers and ice caps  Some water is stored as groundwater Only a very small amount is available in rivers, lakes, and ponds  This means very little freshwater is easily available for drinking, farming, and daily use. Water on Earth –  Facts About 71% of the Earth’s surface is covered with water. Only 3% of Earth’s water is freshwater , and 97% is saltwater . Less than 1% of freshwater is easily available for human use. Most freshwater is locked in glaciers and ice caps . Groundwater is the largest source of usable freshwater for humans. Rivers, lakes, and ponds together hold a very tiny amount of freshwater . Johads in Rajasthan are traditional structures used to store rainwater. Salt pans in Gujarat produce a large amount of India’s salt. The largest ocean on Earth is the Pacific Ocean...
