- About 12% of the earth's surface is made up of metamorphic rocks that are either derived from the igneous or sedimentary rocks based on texture, chemical, and mineral assemblage.
- Some common examples of these rocks are gneiss, slate, marble, and schist, etc that have been formed from the sedimentary processes.
Momentum is a VECTOR quantity because it involves MAGNITUDE AND DIRECTION.
A vector quantity is a quantity which has both magnitude and direction. The formula for momentum is mass x velocity. The mass is a scalar quantity while the velocity is a vector quantity; scalar multiply by vector quantity will give vector quantity .<span />
