Rock Cycle and Rock Formations
Niña Bacani, Arianne Ignacio, Kyle Sopeña, Isaiah Mirafuenntes, Roven Pingol
The rock cycle goes deeper than the surface. In fact, plate tectonic movement which happens in the Earth’s lithosphere is in charge of recycling the rocks, thus, allowing the different processes involved to happen. These so-called processes drive the formation, breakdown, and reformation of a rock. The three types of rocks (metamorphic, igneous, and sedimentary) are greatly intertwined in the mechanism of the cycle and that allows the changes to occur.
Rocks are composed primarily of minerals. Their classifications are based on the way they formed. The rock cycle shows how these can be developed into other kinds through specific procedures. For example, a sedimentary rock, after undergoing intense heat and pressure, will turn into a metamorphic rock. The same can be said for any of the types experiencing an external force included in the cycle.
In this activity, the students will be able to: a. Describe the different classifications of the three major types of rock; b. Discuss the relationships between them and how they are connected to one another; c. Diagram the rock cycle from different steps to various products; d. Know the geological processes that transpire within.
This activity replicates the rock cycle using readily available materials, specifically crayons, hot water, cup, foil, and cutter. First of all, the crayons, made up of assorted colors, had their wrappings removed. After that, they were shredded using a sharp cutter.
The varied shades of shavings were then put on top of one another on a foil.
Pressing down hard mashed the pieces of crayons together. Next, the mashed crayon was wrapped again in a foil then dipped in a cup of hot water long enough for the crayon shavings to combine with one another.
The final step was dipping the foil again in the water so that the wax melts. This cooled into a smooth combination of the crayon pieces.
