Question

Freshwater can be obtained directly from __________________.

(A) Precipitation

(B) Surface run-off

(C) Groundwater

(D) All of the above

Answer 1

Hint: Freshwater environments are categorized as either lentic systems. They are the tranquil waters including ponds, lakes, swamplands and marshes; lotics which are seriatim-water systems; or groundwaters which stream in rocks and aquifers.

Complete answer:

Fresh water is vital to life and yet it is a finite resource. Of all the water on Earth, just 3% is fresh water. Water is divided into saltwater and freshwater. Salt water is 97% of all water and is found mostly in our oceans and seas. Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater. These freshwater habitats are less than 1% of the world’s total surface area.

Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes.

Freshwater is any innately stirring water excluding seawater and saline water. Freshwater is usually categorized by having low meditations of liquified salts and additional completely liquified solids. However, the term explicitly discounts seawater and saline water, it does comprise mineral-rich waters such as chalybeate upwellings. Freshwater may comprise water in ice sheets, ice caps, glaciers, icebergs, bayous, ponds, lakes, rivers, streams, and even underground water called groundwater. 

Freshwater is not constantly drinkable water, i.e., water safe to drink. Much of the earth's freshwater (on the exterior and groundwater) is to a considerable degree unfitting for human ingesting without some handling. Freshwater can effortlessly become contaminated by human actions or owing to naturally happening courses, such as corrosion.

Therefore the correct answer is option ‘D’.

Note: Freshwater is a renewable and mutable, but limited natural resource. Freshwater can only be restocked through the procedure of the water cycle, in which water from seas, lakes, forests, land, rivers, and tanks disperses, shapes clouds, and returns as rainfall. In the vicinity, though, if more freshwater is expanded through human actions than is naturally reinstated, this may result in abridged fresh water accessibility from the exterior and underground sources and can cause grave impairment to adjacent and connected environments.
