While communism is a system based around a theory of economic equality and advocates for a classless society, fascism is a nationalistic, top-down system with rigid class roles that is ruled by an all-powerful dictator.
HEAT AND PRESSURE-. What happens to cookie dough when you put it in the oven? The heat of the oven produces changes in the ingredients that make them interact and combine. Without melting the dough, the heat changes it into a whole new product - a cookie. A similar process happens to rocks beneath the earth's surface. Due to movements in the crust, rocks are frequently pulled under the surface of the earth, where temperatures increase dramatically the farther they descend.
Igneous rocks are formed when magma or lava cools and hardens. An igneous rock becomes a sedimentary rock through weathering and erosion of the igneous rock. The igneous rock, exposed to weathering processes at the surface, breaks into smaller pieces.etamorphism is the change in form of a geological unit (like a rock) through metamorphic processes (must be in solid state). These processes include temperature and pressure changes as well as chemical changes. A sedimentary rock can be transformed into an igneous rock and then into a metamorphic.
