A Lake is a body of fresh or salt water of considerable size and land surrounds this body of water. This body of water is inland and is not a part of the ocean but is larger and deeper than a pond. We find natural lakes on Earth in mountainous areas, rift zones, and areas with ongoing or recent glaciations. We also find other lakes in basins or along the courses of mature rivers.
A Well is an excavation created in the ground by digging, driving, or drilling to access groundwater in underground aquifers. An electric pump, a hand pump, or a mechanical pump draws the well water. Wells can vary greatly in depth, water volume and water quality. Well water typically contains more minerals in solution than surface water and may require treatment to soften the water by removing minerals such as arsenic, iron, and manganese.
