Answer:
Explanation:
This is because gypsum and limestone contains compounds that are responsible for the hardness of water
Limestone is made of calcium carbonate, whereas gypsum is made of calcium sulfate. They can lead to hard water due to the presence of dissolved calcium (minerals).
Hard water is the dissolved minerals like calcium, magnesium, etc., in water that alters the water quality. They have high mineral content that percolates bicarbonates, carbonates, and sulfates salt of minerals.
The minerals get dissolved from the water that runs over the limestone and gypsum rocks resulting in substantial damage to the infrastructures, dry skin, and hair.
Hard water is not good for many uses due to its high mineral content that accumulates in the environment leading to land degradation and harm to the plants through the roots.
Therefore, the places rich in limestone have hard water due to dissolved minerals.
