6.10B CLASSIFY ROCKS Rock - __________________________________________________________ _____________________________________________ A natural, solid mixture of m minerals or grains. ________________________________________________________________ A naturally occurring, inorganic solid with a definite chemical composition Mineral - ________________________________________________________ and an orderly arrangement of atoms. ________________________________________________________________ How do scientists classify rocks? __________________________________________ ________________________________________ _____________________________________________________________________ Scientists use the process of formation for rocks to classify them into three different groups: igneous, sedimentary, or metamorphic. _____________________________________________________________________ ROCK TYPES 3 MAJOR TYPES Igneous rocks form by the cooling and solidification of how it forms… forms…_____________________________________________ ______________________ magma or lava ________________________________________________________________________________ • IGNEOUS Molten rock that erupts on Earth’s surface Lava - __________________________________________________________ ________________________________________________________________ Molten or liquid rock underground Magma - ________________________________________________________ ________________________________________________________________ Where would you expect igneous rocks to form? __ ______________________________ ____________________________ Igneous rocks form in a variety of environments including subduction ____________________________________________ _____________________________________________________________________ _________________________ zones, mid-ocean ridges,, and hot spots where volcanoes are common. _____________________________________________________________________ Sedimentary rocks form where sediments are how it forms… forms…_________________________________________ ______________________ compacted and cemented. ________________________________________________________________________ ________________________________________________________________________________ • SEDIMENTARY Rock material that forms where rocks are broken down into Sediments - ______________________________________________________ smaller pieces or dissolved in water as rocks erode. ________________________________________________________________ What forces cause rocks on Earth’s surface to break down? __ _____________________ ___________________ Forces such as wind, running water, ater, _______________________________________ ice and even gravity cause rocks on Earth’s ______________________________ _____________________________________________________________________ surface to break down. _____________________________________________________________________ • METAMORPHIC Metamorphic rocks form______________________ when rocks are exposed to how it forms… forms…_________________________________________ extreme temperature and____________________ pressure. ____________________________________________________________ ________________________________________________________________________________ The series of processes that _____________________________ change one type of rock Rock Cycle - _________________ _____________________________________________________ into another type of rock. ________________________________________________________________ Explain the major PROCESSES of the ROCK CYCLE. A tectonic force that forces rocks onto Earth’s ________________________________ surface UPLIFT _______________________________________________________________________ _______________________________________ ________________________________________________________________________________ The depositing of sediments in a new place______________________________ such as_______________________ in rivers or streams, DEPOSITION _______________ ______________ DEPOSITION _____________________________ _____________________ ________ _______ _______ deserts and valleys. ________________________________________________________________________________ COMPACTION + CEMENTATION ______________________ _____________________________ ___________________________________ ______________________________ A process in which the weight from the layers of sediments forces out fluids and decreases the ________________________________________________________________________________ space between sediment grains and dissolved minerals crystallize. The breaking down of rocks into smaller pieces and carrying of WEATHERING + EROSION _____________________________ ____________________________________ ________________ ___________________________ them to a new location by wind, water, ice and gravity. ________________________________________________________________________________ ________________________________________________________________________________ Fill in the missing information for the ROCK CYCLE.
