5.1 Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Flint vs Pumice Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Flint and Pumice Reserves. Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Flint vs Pumice information and Flint vs Pumice characteristics in the upcoming sections.
