Question

what percentage of fresh water is found as ground water. is it accessible to us​

Answer 1

Answer:

Earth is known as the "Blue Planet" because 71 percent of the Earth's surface is covered with water. Water also exists below land surface and as water vapor in the air. Water is a finite source. The bottled water that is consumed today might possibly be the same water that once trickled down the back of a wooly mammoth. The Earth is a closed system, meaning that very little matter, including water, ever leaves or enters the atmosphere; the water that was here billions of years ago is still here now. But, the Earth cleans and replenishes the water supply through the hydrologic cycle.

The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere. Still, much of the 0.3 percent that is useable is unattainable. Most of the water used by humans comes from rivers. The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation. Humans can use both ground and surface water.

Answer 2

Answer:

$0.75\%$ of water is found as water and it's accessible to us.

Explanation:

• Earth’s surface is roofed with 29 piece of land and 71 you look after water. Out of 71% of water, 97% of water is saltwater which is present in oceans, seas, and saltwater lakes.
• Remaining 3% of water present on the land is freshwater which is present within the type of glaciers, ice caps, groundwater, lakes, rivers, and within the atmosphere as vapour.
• Out of three of freshwater, 2.5% of the earth's freshwater can't be used because it's locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted, or lies too far under the Earth's surface to be extracted at a reasonable cost.
• .0% of freshwater is found in ice caps and glaciers, 0.75% of freshwater is within the ground as groundwater, 0.009% in freshwater lakes, 0.001% within the atmosphere, 0.0001% within the rivers.
• Nowadays, groundwater is employed because the main source of water in major cities.
• Naturally, Saltwater will be become freshwater by a combined process called evaporation condensation.
• water on the bottom enters into the deeper parts of the bottom via porous materials. This water is named groundwater.
