How Does Granite Change Into Sandstone? - Reference

Granite changes into sandstone by means of weathering and erosion. Through the passage of time, fragments of granite are broken down into smaller pieces, or sediments, which are transported and deposited at the bottom of the oceans or rivers. These particles form layers of sand and pebbles that undergo compaction and cementation to create ...

Limestone vs Granite: What Are They, And What's The Difference?

The hardness of limestone averagely ranges from three to four while that of granite from six to seven. The heat capacity of limestone is 0.91 KJ/Kg K, whereas that of graphite is 0.79 KJ/Kg K. Therefore, with such properties and other compounds in each stone, limestone is more inclined to be pressure-resistant while granite is heat resistant.
