The burner mimics the heat coming from the earth’s molten core while folding the tin foil mimics the pressure exerted by tons of rocks piled on top of each other. Then a burner is used to heat the tin foil. The tinfoil is then folded to mash the chocolate together. The layering process mimics mother nature’s erosion where rock particles are moved from the mountains down into river beds, streams, oceans, etc. Then the result of the process is layered on top of a tin foil. Part of the mixture is colored black or dark brown and the other is colored white. One could easily see the effect of the mixture. Then the black and white chocolate powder – it could no longer be called chocolate chips because of the fine consistency of the chocolate – are mixed. But in the latter part, the chips are reduced to an almost fine powder. Going back to the experiment the constant cutting and breaking of the chocolate chips will reduce it into something that is of finer consistency.Īt the beginning of the experiment, the chocolate chips are more stable and solid that it requires a knife to cut through and break it into pieces. The white and black chocolate chips also help in visualizing a feature of the rock cycle process where minerals are mixed or moved from one place to the next. This represents the different mineral compositions found in rocks. There are two kinds of chocolate chips one is white and the other is black. The process of cutting and breaking down the chocolate chips continues until the chips are simplified further. This action mimics the “weathering” process experienced by exposed igneous rocks. The proponent of the experiment began to cut the chocolate chips into pieces and then pulverize them using hands and fingers. To fully understand the rock cycle an experiment was conducted using white and black chocolate chips to resemble rock matter. Let`s start Importance of Rock Cycle: Rock Formation Experiment If metamorphic rocks are exposed to greater pressure and more heat then the rocks can melt and transform into magma. The result is a new type of rock called metamorphic which comes from the term metamorphosis or transformation. The weight of the rock and the heat coming from the earth’s molten core will cause heat and pressure to change the composition of the rocks, specifically the mineral content of the rocks. Sedimentary rocks can be broken down even further and then hundreds of years of the “weathering” and erosion process will result in the piling up of rocks. Examples of nonclastic sedimentary rocks are limestone, rock salt, rock gypsum, and Chert. But when sedimentary rocks are deposited deep in the ocean non clastic sedimentary rocks are formed and characterized by the minerals found in them. If sedimentary rocks are deposited in rivers and in places where it is exposed to wind and water a different type of sedimentary rocks are formed – clastic sedimentary rocks. Igneous rocks broken down by natural forces can then be transported and deposited by streams, wind, glacier water, or ocean currents. Rainwater as well as wind and earthquakes can speed up the weathering process as well as erosion. When igneous rocks are exposed to the elements they will undergo a process called “weathering” and if it breaks down it will experience erosion. Since magma contains rock matter and minerals that was mixed by the high temperatures when magma cools down and form igneous rocks one can also discover the different kinds of minerals contained in the said igneous rocks. When magma cools down it will form igneous rocks. If magma finds its way underneath a volcano, the pressure builds up, and finally, at a critical point, the volcano will erupt, spewing magma. The very hot magma will move up from below. Rock matter subjected to this level of heat can be transformed into a liquid state and therefore can be moved with ease. It is common knowledge that heat, especially high temperatures causes substances to move. Underneath the earth’s surface are superheated rocks that are called magma. Why Is the Rock Cycle Important: Rock Formation Slate (Metamorphic rocks) – these durable rocks can be used as roofing material for roofs.
