Question

Which statements about freshwater sources are true? Check all that apply. Only about 3 percent of Earth’s water is fresh water. Most of the fresh water on Earth is groundwater. About 75 percent of the fresh water on Earth is frozen in ice sheets. The largest source of usable fresh water is groundwater. More fresh water is in the atmosphere than in rivers and lakes.

Answer 1

The correct answers are:

- Only about 3 percent of Earth's water is freshwater;

The amount of freshwater, out of all the water on the planet, is very low, only around 3%. Considering how much we spend of it, and how much we are polluting it, it is alarming, and urgent measures have to be taken in order to preserve this essential life element.

- About 75 percent of the freshwater on Earth is frozen in ice sheets;

Not just being only 3% out of the total water reserves on the planet, the majority of the freshwater is not actually usable, as around 75% (68.7% by the newest data) of it is actually frozen. The ice sheets on the poles, as well as the glaciers, are holding most of the freshwater in them, and even if they melt, the water will become saline and not usable because it will mix with the ocean waters.

Answer 2

Answer:

Options (1) and (3)

Explanation:

Water is the most vital element on earth and all living organisms are dependent on it. It supports life and is found in the different parts of the earth and in different forms. The majority of the earth is comprised of water and out of all the total water present on earth, about 97% of it is saline water and the remaining 3% is the only freshwater.

From this total freshwater composition, approximately 75% of it is the water present in the form of glaciers and ice in the polar region, other 24% is the groundwater, and the remaining 1% includes all the surface water present on earth that includes the waters of rivers, lakes, and ponds.

The main source of usable freshwater is the waters trapped in the glaciers and ice. Some of the water is also present in the atmosphere in the form of vapor but they are significantly less in amount.

Thus, the correct answers are options (1) and (3).
