Question

Water is not usually thought of as a solid, and only a small fraction of the Earth's water is in a solid state, in the form of ice. This ice includes all forms of frozen water, from the ice sheets at the North and South poles to icebergs, ice on the top of mountains, frozen lakes in the winter, or even the ice in a freezer. Though all the ice on earth is part of the hydrosphere, the frozen aspect is known as the cryosphere. This frozen water is three-fourths of the earth's freshwater, which makes it quite important. Identify other sources of fresh water.

विकल्प

• rivers, lakes and streams

• underground water

• reservoirs and dams

• All of the above

Answer 1

All of the above

Explanation:

Besides the frozen water stored in the cryosphere, other sources of freshwater on Earth include:

1. Rivers, lakes, and streams: These are surface water sources and are commonly used for drinking, irrigation, and industrial purposes.

2. Underground water: Also called groundwater, found in aquifers, wells, and springs, it is a major source of freshwater for agriculture and domestic use.

3. Reservoirs and dams: These are man-made sources created by storing river water, which is then used for various purposes like hydroelectric power, irrigation, and municipal water supply.
