Most of Earth's freshwater is stored in glaciers and ice caps, with a small accessible percentage found in lakes, rivers, streams, and reservoirs. Groundwater also plays a key role in the freshwater cycle, but these sources are often depleted faster than they are replenished.
The most significant reservoir of Earth's freshwater is stored in glaciers and ice caps. These make up about 68.7% of all freshwater on Earth. On the other hand, only 2.5% of the Earth's total water volume is freshwater, and less than 1% of this fresh water is easily accessible to living things, being found in lakes, rivers, streams, and reservoirs.
Groundwater is important in the cycle of fresh water. This water, found underground in the pores of soil and rocks, eventually finds its way to streams or lakes and then becomes a part of surface water again. Most drinking water or irrigation water is drawn from aquifers, which are reservoirs of groundwater. However, these are often being used up faster than they can be restored by water from the surface.

c. no continents occupied the Northern Hemisphere.
d. the countries found in the Southern Hemisphere today were once centered over the North Pole.
The answer is A. There is evidence from geologic rocks that there was an ice age 2.4 billion years ago and the glaciers had reached Western Australia and India. This ice age is associated with the cooling of the earth due to the Great Oxygenation event when the earth was filled with oxygen produced by photosynthetic organisms hence reducing the amount of greenhouse gases in the then atmosphere. There have been four other major ice ages after that.
