Super Simple Rock Cycle Projects: Science Activities for Future Petrologists
4 WHAT IS THE ROCK CYCLE The rock cycle is a geological process It is how rocks are formed Rocks are also changed and destroyed in the cycle Each kind of rock can become another kind over and over again Most of Earth's crust is made up of rocks They can be found underground and on Earth's surface Rocks also shape landforms around us Rocks are made of minerals Some are made of one mineral Others are made of many minerals Rocks can be many shapes CRUMBLING ROCKS colors and sizes
5 STONE FENCE Rocks are important They have had many purposes throughout history Their uses include tools weapons and building supplies Minerals from rocks are used to create chemicals and other substances we need STONE ARROWHEADS
TYPES OF ROCKS 6 Three kinds of rocks make up the rock cycle Each kind can become one of the other kinds through the rock cycle IGNEOUS ROCKS 3 SRLS Igneous rocks form from magma Magma cools and hardens into igneous rocks These rocks can be formed underground They can also be formed above ground after a volcano erupts Granite is a type of igneous rock
7 SEDIMENTARY ROCKS Erosion helps form sedimentary rocks Wind and water erode rocks The rocks break into pieces called sediments The sediments pile up in layers Pressure pushes the layers together This creates sedimentary rocks Sandstone is a type of sedimentary rock METAMORPHIC ROCKS Metamorphic rocks start underground as other kinds of rocks The rocks change due to heat and pressure within Earth This creates metamorphic rocks Marble is a type of metamorphic rock
