On the planet earth, most of the freshwater exists as ice caps and glaciers. Out of the remaining freshwater, the largest proportion
Answer & explanation
Answer: (c) exists as groundwater
Answer: (c). Ice holds most of Earth's freshwater, roughly 70–78%. Groundwater holds most of the rest, roughly 22–30%. Lakes, rivers, soil moisture and the atmosphere together hold only a tiny fraction, well under 1%.
- ✗ (a) Water held in the atmosphere as vapour and clouds is a minute fraction of freshwater, far smaller than groundwater.
- ✗ (b) Freshwater lakes and rivers are visible and important, but together they hold only a tiny share of freshwater, much smaller than groundwater.
- ✓ (c) Groundwater makes up roughly 22–30% of all freshwater. That makes it by far the largest store after ice.
- ✗ (d) Soil moisture is a very small store of freshwater, far below groundwater.
Remember · Freshwater stores: ice (~70–78%) > groundwater (~22–30%) > everything else (lakes, rivers, soil moisture, atmosphere) together, well under 1%.
