Answer:

Ans to first question: 3 percent of the water is fresh

Ans to second question: Only confined aquifers can produce artisan wells

Explanation:

The earth is largely covered by water, upto 70 percent, and only about 3 percent of the entire water is fresh, which can be used for agricultural purposes or for other domestic uses. Only 1 percent of this fresh water portion is easily reached by us while the remaining portion are found in snowfields and glaciers.

The remaining water portion are deemed saline.

Artesian well are wells with its water being under pressure and can be said to flow to the surface naturally without being pumped. Only confined aquifers can produce artisan wells

Answer:

Question 1. The percentage is 3%.

Question 2. Only confined aquifers can produce artesian wells.

Explanation:

The remaining 97% of water is saline and ocean-based, thus, not adequate for consumption. And with from that small 3%, only about 1% is accessible to us, because the rest is located in glaciers and snowfields.

Regarding the second question, for an artesian well to form, a confined aquifer must exist. A confined aquifer stores groundwater under positive pressure, caused by layers of impermeable rocks. Any well drilled into the confined aquifer is called an artesian well.
