Answer 1

The type of water that can remain in the ground as groundwater for up to 10,000 years is called fossil water. This type of water is usually contained in an undisturbed place usually underground. This water is usually infiltrated for millennia and often different from the present.

Answer 2

Answer: Fossil water

Step-by-step explanation
Water that is stored near the earth's surface goes through cycles in which evaporation, condensation, and subsurface water movements recycle the water.
For example, water moves from rivers into the oceans and evaporated water condenses in the clouds and returns to the earth as precipitation.

On the other hand, fossil water can remain under the earth as groundwater for up to 10,000 years.
Furthermore, the polar caps can store water in the frozen form as ice for periods much longer than 10,000 years.
