After a long time the sediments can be cemented together to make sedimentary rock. In this way, igneous rock can become sedimentary rock. All rock can be heated. But where does the heat come from? Inside Earth there is heat from pressure push your hands together very hard and feel the heat. There is heat from friction rub your hands together and feel the heat.
There is also heat from radioactive decay the process that gives us nuclear power plants that make electricity. So, what does the heat do to the rock? It bakes the rock. Baked rock does not melt, but it does change. It forms crystals. If it has crystals already, it forms larger crystals. Because this rock changes, it is called metamorphic. Remember that a caterpillar changes to become a butterfly. It also has the highest melting point and conducts heat five times better than the second-best element, silver.
Have you ever made a rock collection? Part of the fun is gathering as many different rocks as you can find. But even though rocks come in many different colors, shapes, and sizes, they all fit into one of three categories based on how they were formed.
Learn about the rock cycle steps, the three main types of rocks, and what happens when rocks get so hot that they melt! Unwrap four different-colored Starburst candies. Have an adult use the scissors to help you cut each piece of candy into pieces. Next, rub your palms together back and forth quickly for several seconds. Then pick up the pile of candy and push the pieces together to form a ball.
Your ball should look lumpy with the candy pieces visible. Next, have an adult help you use your heat source to soften the lumpy ball of candy.
Some ideas include rolling it with a rolling pin, placing a pile of heavy books on top of it, stepping on it, or whatever else you can think of! Then put it back in the wax paper and repeat the process of applying pressure, this time trying a new technique if you want. When you remove the Starburst from the wax paper now, it should be soft and pliable, so you can easily roll it into a ball.
Have an adult help you use your heat source to apply enough heat to completely melt the lump of candy. Do not put aluminum in a microwave! Have an adult use tongs to remove the foil container from the heat source and place it somewhere out of reach to allow it to cool. How is the candy different now? The rock cycle is the entire process of forming rocks, and like a circle, it has no beginning or end. In this rock cycle project, we simulated the formation of sedimentary rocks by pressing the pieces of Starburst into a lump.
We simulated the formation of metamorphic rocks by adding heat and pressure in steps 4 and 5. The final three steps of the project show how igneous rocks are formed. Give it a try! After you finish this article, we invite you to read other articles to assist you in teaching science at home on the Homeschool Hub, which consists of over free science articles! Home Science Tools offers a wide variety of science products and kits.
Find affordable beakers, dissection supplies, chemicals, microscopes, and everything else you need to teach science for all ages! But, we can help. Is STEM just another fad?
Or are STEM fields the key that can unlock the future for not only young people but for the world? Let's dive in. Science can be split up into several fields of study. We're going to dive into what space and earth sciences are—and some of their A KWL Chart is an interactive graphic organizer that allows students to take control of their own learning by organizing existing background knowledge before, during, and after a lesson, chapter, or learning that takes place from using a science kit Because every teacher-student situation is different, there is no one science curriculum that is best for every homeschool family How long might it take for this entire process to be completed?
Unless they are re-eroded and moved along, sediments will eventually be buried by more sediments. At depths of hundreds of metres or more, they become compressed and cemented into sedimentary rock. Again through various means, largely resulting from plate-tectonic forces, different kinds of rocks are either uplifted, to be re-eroded, or buried deeper within the crust where they are heated up, squeezed, and changed into metamorphic rock.
