there is no real answer to that because we drink the same water the dinos lived on and if water can stick around that long then i think it will stay around a lot longer than the human race.
The rain, It rained heavily for a long period of time, (Prolonged Rain) , it rained an exceptional amount of rain in 8 hours, 2 inches in 2 hours. as well as that, deforestation, and the fact that the soil was saturated deforestation is when trees are cut down. when they are cut down theres nothing to suck of the water from the ground (roots) and no leaves to catch the water interception
Most ancient civilizations needed the fertile land, food sources (water-based fowl, fish, etc.), and trading opportunities found near rivers to support their community. Over time, commerce and population would grow, and with it would develop a full-fledged civilization. They could then use their clever location to defend themselves from attackers, to reach other main hubs of civilization to trade, and to establish a navy. hi guys
Because they always need water
new mexicos greatest shortcoming is water.
Water shortages, unequal distribution, pollution
Water. H2O
It is not necessary to refrigerate a cold water extraction with pills as long as it is stored in a cool, dark place away from direct sunlight and heat. Make sure to keep it out of reach of children and pets.

Hot water extraction is sometimes refered to as steam cleaning.
The best way to find information about water extraction might be Wikipedia where one can find information about both cold water extrection and hot water extraction. On a wedside called Wikihow one can find a 13 steps manual how to perform a cold water extraction which is nicely illustrated.
Extraction (Solid-Liquid Extraction)
Desalination is the extraction of sodium chloride to obtain drinking water, extraction of salt from petroleum, from water wastes etc.
Underground water can typically be found in aquifers, which are layers of permeable rock or sediment that hold water. These aquifers are replenished by precipitation and can be tapped into through wells for groundwater extraction. Areas with high water tables or near rivers and lakes are also likely to have underground water.
yes
Soda or juice is not recommended as a substitute for water in a cold water extraction method. Codeine is slightly soluble in acidic solutions like soda or acidic juices, but it may not dissolve as effectively as in water, affecting the extraction process. It is best to stick with water for a cold water extraction to ensure optimal results.
No, ethanol and water are miscible. For an extraction, you want two solvents that are immiscible (mutually insoluble). Standard choices for the organic phase are ethyl acetate or dichloromethane. For the aqueous phase, use water, aqueous acid or aqueous base, depending on the compound you are trying to isolate.
