Question

What are the "types" of water on the planet? How much of it is readily available for humans? How do aquifers work? In what ways do we "use" freshwater? (Subject: Environmental Biology)

Answer 1

• Ocean water: 97.2 percent.
• Glaciers and other ice: 2.15 percent.
• Groundwater,: 0.61 percent.
• Fresh water lakes: 0.009 percent.
• Inland seas: 0.008 percent.
• Soil Moisture: 0.005 percent.
• Atmosphere: 0.001 percent.
• Rivers: 0.0001 percent.

Freshwater makes up a little portion of all water on the planet. While about 70 percent of the world is secured by water, just 2.5 percent of it is fresh. The rest is saline and sea based. And, after its all said and done, only 1 percent of our freshwater is effortlessly open, with quite a bit of it caught in ice sheets and snowfields.

Water movement in aquifers is exceedingly needy of the penetrability of the aquifer material. Porous material contains interconnected splits or spaces that are both sufficiently various and sufficiently huge to enable water to move uninhibitedly. In some porous materials groundwater may move a few meters in a day; in different spots, it moves just a couple of centimeters in a century. Groundwater moves gradually through generally impermeable materials, for example, mud and shale. In the wake of entering an aquifer, water moves gradually toward bring down lying places and in the long run is released from the aquifer from springs, saturates streams, or is pulled back starting from the earliest wells. Groundwater in aquifers between layers of ineffectively penetrable shake, for example, mud or shale, might be kept under strain. On the off chance that such a limited aquifer is tapped by a well, water will transcend the highest point of the aquifer and may even spill out of the well onto the land surface. Water bound thusly is said to be under artesian weight, and the aquifer is called an artesian aquifer.

People utilize freshwater for drinking water, to inundate crops, as a feature of sanitation system, and in modern industrial facilities, to give some examples. Water spent from groundwater, waterways and lakes is renewed by rain and snowfall.
