The correct option is A-4, B-1, C-2, D-3
Explanation
The Earth's hydrosphere encompasses all water present on the planet. This water is distributed unevenly across oceans, continents, and the atmosphere. The vast majority exists as saline water, while fresh water constitutes a very small fraction.Distribution Analysis:
- Oceans (A): The oceans are the largest reservoir of water, containing approximately 97.3% of the total global water volume. This water is saline and not directly fit for human consumption. (Matches 4)
- Ice-caps (B): The largest portion of Earth's fresh water is locked in solid form within ice caps and glaciers, accounting for approximately 2.0% of total water. (Matches 1)
- Ground water (C): Subsurface water, or groundwater, represents about 0.68% of the total water. It is a critical source of fresh water for many regions. (Matches 2)
- Rivers (D): Surface water flowing in rivers constitutes a minute fraction of the hydrosphere, approximately 0.0001%. (Matches 3)
Key Takeaway: Over 97% of Earth's water is saline ocean water. Of the remaining fresh water, the majority is stored in ice caps and glaciers, followed by groundwater, with surface water bodies like rivers comprising a negligible percentage.
