Read More6/1/2018· Formation of extrusive rocks : These rocks are also known as volcanic rocks, because they are formed by the solidification of lava on the earth’s surface. As on the outer surface of the earths’ crust the rate of cooling and solidification is more rapid than in the interior, the different minerals composing the magma have less time to become crystalline.

Enhanced Weathering is a carbon capture process that could remove over 2bn tons of CO2 each year (for comparison, the U.S. emitted 5.3bn in 2018), explains Benjamin Houlton at the University of California.
Read MoreA crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials, so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified
