Chalk vs Blueschist

Chalk vs Blueschist 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 Chalk and Blueschist Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature. 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.
