Gritstone vs Chalk

Gritstone vs Chalk 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 Gritstone and Chalk Reserves. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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.
