Mohs Hardness Scale:

* Marble: 3-5

* Granite: 6-7

The Mohs Hardness Scale measures the resistance of a mineral to scratching. A higher number indicates a harder material.

Reasons for Marble's Softness:

* Marble is primarily composed of calcium carbonate, which is a relatively soft mineral.

* It has a crystalline structure that is more susceptible to scratching and abrasion.

Uses:

* Marble: Due to its softness, marble is often used for sculptures, decorative items, and flooring in areas with low traffic.

* Granite: Its hardness makes it ideal for countertops, kitchen sinks, and exterior cladding.

Conclusion:

While both marble and granite are natural stones, marble is significantly softer than granite. This difference in hardness affects their durability, suitability for different applications, and susceptibility to scratches and stains.
