Metamorphic rock slideshow. It defines metamorphism as the change in form of pre-existing rocks beneath the earth's crust due to heat and/or pressure. Discover how they form, the types, examples, and how to identify them. How to use metamorphic in a sentence. These conditions often stretch, twist and fold the rock as it cools. Metamorphic rocks are type of rock that formed when pre-existing rocks (parent rocks) undergo significant physical or chemical changes under high pressure and temperature, without melting completely. There are two types of metamorphism: contact metamorphism near intrusions of lava or magma, and regional metamorphism over wide areas from the large-scale forces of This document provides information on different types of rocks, including their properties and uses. It discusses igneous rocks like granite, syenite, and diorite; sedimentary rocks such as sandstone, limestone, and shale; and metamorphic rocks including gneiss, quartzite, and marble. Includes slides with rock descriptions to guide the auction and project. Metamorphic grade is general term for describing the relative temperature and pressure conditions under which metamorphic rocks form. Feb 24, 2024 · Learn about metamorphic rocks in geology. The parent rock can be sedimentary, igneous, or even a different sort of metamorphic rock. ), setting (orogenic, burial), and protolith. It defines metamorphism as changes in mineralogy and/or texture in rocks due to physical and chemical conditions different from surface conditions. Metamorphism is classified based on process (contact, regional, etc. This document discusses metamorphism and geological problems encountered in civil engineering projects. In general, if the protolith of a metamorphic rock can be determined, the rock is described by adding the prefix meta- to the protolith rock name. Feb 2, 2023 · Metamorphic rocks form due to the transformation of preexisting rocks in response to environmental changes such as heat, high pressure, and mechanical stress. Regional metamorphism is subdivided into orogenic Metamorphic rocks are one of the three great divisions of all rock types, and so there is a great variety of metamorphic rock types. . Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Specifically, it describes the composition and properties of minerals, how the three main rock types are formed through igneous, sedimentary, and metamorphic processes, and Mar 31, 2004 · Grade of Metamorphism As the temperature and/or pressure increases on a body of rock we say the rock undergoes prograde metamorphism or that the grade of metamorphism increases. The meaning of METAMORPHIC is of or relating to metamorphosis. Exposure to these extreme conditions has altered the mineralogy, texture, and chemical composition of the rocks. Areas of Focus: Characteristics and classification of igneous, sedimentary, and metamorphic rocks. The document outlines specific learning outcomes for a lesson on rock types. At the end of the lesson, students will be able to: identify and describe the three basic rock types; describe how each rock type forms and define their environments of formation; describe how rocks are transformed through the rock cycle; and identify and describe different geologic processes in the rock cycle Creative Project: Rock Auction: Students bid on rocks with monopoly money and create a poster project on their "purchased" rock. This document discusses metamorphism and provides definitions and classifications. Metamorphic rocks are one of the three great divisions of all rock types, and so there is a great variety of metamorphic rock types. Metamorphic rocks are one of the three great divisions of all rock types, and so there is a great variety of metamorphic rock types. It discusses the main topics of minerals, igneous rocks, sedimentary rocks, and metamorphic rocks. For each rock type, the document outlines characteristics such as chemical composition, hardness, and This document provides an overview of minerals, rocks, and the rock cycle presented by a student from Suez University. Oct 27, 2021 · Metamorphic rocks form when high temperatures and pressure act on a rock to alter its physical and chemical properties (metamorphism means 'to change form'). Conditions like these are found deep within the Earth or where tectonic plates meet. Oct 19, 2023 · Metamorphic rocks start as one type of rock and—with pressure, heat, and time—gradually change into a new type of rock. Metamorphic rocks have been modified by heat, pressure, and chemical processes, usually while buried deep below Earth's surface. Sep 1, 2025 · Metamorphic rock, any rock that results from the alteration of preexisting rocks in response to changing conditions, such as variations in temperature, pressure, and mechanical stress, and the addition or subtraction of chemical components. 2z kyv6 ryaah mxa bc 6pe dwc xh dfif cj2oh
