Chalk vs Scoria

Chalk vs Scoria 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 Scoria Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Chalk vs Scoria information and Chalk vs Scoria characteristics in the upcoming sections.
