Some rocks are millions of years old!Student 2: You mean, some rocks out on the playground are the same rocksthat dinosaurs walked on?Teacher 2: Yes, that’s possible!Student 3: How can that be? Wouldn’t they have been crushed or buried?Teacher 1: Actually, you are right! Because of the rock cycle, rocks do getcrushed and buried, but that doesn’t mean they disappear.Student 1: What happens to rocks in the ground?Teacher 2: Great question! Let’s explore the rock cycle with a little help fromthe main participants- rocks!Sediment 1: Hey there! I am a piece of sediment!Student 2: What is sediment?Sediment 2: I’m another piece! Sediments are pieces of rock that have beenweathered down from forces of nature.Wind: Like me, the wind! I break down rocks with my powerful strength!
Sediment 3: Yes, the wind weathers rocks and we are carried away by erosion.Student 3: What is erosion?Wind: Erosion is the movement of sediment that has been weathered away.Water: I help with erosion as well. You can find me in little streams or large rivers.My flowing helps transport pieces of sediment.Ice: Me too! Me too! Glaciers play a role in weathering and erosion as well. Myweathering process is a bit slower than wind and water, but I am still very strong!Water: We all weather and erode sediment and eventually deposit the pieces in anew place.Ice: This is called deposition. Sediment piles up over time.Wind: Eventually, the sediment is compacted and cemented together.Water: That means it is pressed together tightly.Sedimentary Rock: Then we have created sedimentary rock! That’s me!Student 3: I’ve heard of sedimentary rock. The name makes sense since it ismade of sediment.Teacher 1: Sandstone and shale are some examples.Sedimentary Rock: Yes they are! I am made of many layers of sediment overtime. That’s why you can find pebbles, stones, and even fossils in me.Student 1: Wow! What happens though when you stay buried in the ground?Crust: That’s where I come in. I am the Earth’s crust, the outer layer of theEarth. Did you know I am always moving?Student 2: No way!Crust: Yes! I pull rocks beneath the surface of the earth. The farther down theygo, the hotter the temperature. Not only is there a lot of heat, but also there is alot of pressure.
Student 3: Where is the pressure coming from?Crust: There are a lot of rocks still on the surface that are now pressing down onthe rocks below the surface.Metamorphic Rock: That’s where I come in. Metamorphic rocks are formed fromheat and pressure in the earth’s crust.Teacher 2: Some examples are slate and marble.Metamorphic Rock: That’s right! Over time, I can be pushed even further downinto the mantle.Mantle: Did someone say my name?Metamorphic Rock: I did! What happens when metamorphic rock gets to you?Mantle: I am the layer under the crust. I contain molten rock, otherwise known asmagma.Magma: Hot hot hot! That’s me!Mantle: Any rock that gets pushed down to the mantle will melt because thetemperature is very high.Magma: The rock will turn to magma. Sometimes I can help a rock to rise back upand cool again.Intrusive Igneous Rock: The slow cooling of magma forms intrusive igneous rock.You may have seen intrusive igneous rock when you look at granite.Magma: There’s another route that magma can take as well. Do you know howmagma gets to the surface of the earth?Student 1: Through a volcano?Volcano: That’s right! A volcano provides an opening for magma. When I erupt,the magma is forced to rise from the mantle.
Lava: That’s where I’m from. Lava is magma that has reached the earth’ssurface. Once I get out of the volcano, the outside temperature is much colderthan deep in the earth. This means I quickly cool down.Extrusive Igneous Rock: This quick cooling causes lava to harden and formextrusive igneous rock.Teacher 1: An example is basalt or obsidian.Extrusive Igneous Rock: Exactly right! Thanks to me, an entire island can beformed!Student 2: That’s pretty impressive. Now that we are back on the earth’ssurface, what happens next?Teacher 2: The earth is constantly changing. Weathering and erosion neverstops.Student 3: So igneous rock will become sediment because of wind, water, andice? It happens all over again?ALL PARTS: That’s the rock cycle!

Rock Cycle Scientists have created a model to show how rocks slowly change over time. The rock cycle shows the processes that create and change rocks. The three types of rocks shown in the rock cycle are igneous, metamorphic, and sedimentary. The rock cycle shows how rocks can change from one type of rock to another.
