What is the difference between granite and marble?
1, with different appearance.

Marble and granite are quite different in appearance patterns. Marble is richer in color and changeable in pattern, which is freehand like landscape painting. Granite has no obvious patterns, and the patterns on the outside are dotted, which is relatively simple.

2. The reasons are different.

In addition to the huge differences in appearance, the reasons for their formation are also very different. Marble is a metamorphic rock formed by high temperature and high pressure in the crust. Granite is magmatic rock formed by magma jet cooling in the earth's crust or cooling after high temperature melting of rocks.

3. Different hardness

Their hardness is also very different. Marble has low hardness and is easily eroded by air and rain, so its Mohs hardness is generally 3-5. Granite has a high hardness and is not easy to process, so its Mohs hardness is generally 6-7.
