Metamorphic Rocks A GALLERY. Foliated Metamorphic Rocks Foliated: Minerals are aligned in layers or rows. “consisting of thin sheets or laminae” Banded:
Metamorphic Rock Practice. Slate -foliated -parent rock is slate.
Metamorphic Rocks Metamorphic rocks are igneous, sedimentary, or other metamorphic rocks that have undergone extreme heat and/or pressure. The extreme.
METAMORPHIC ROCKS Form when heat and/or pressure change existing rock into a new rock through recrystallization Types of Metamorphism –Regional Metamorphism.
Which type of igneous rock forms on the surface of Earth from lava? Intrusive OR Extrusive.
4-4 pgs IN: What are some ways that sedimentary rock can form? Can you classify the four we looked at?
Metamorphic rocks form when the crust is exposed to rising pressure and temperature conditions. What processes can raise the pressure and temperature of.
Rocks Study Slides. Igneous Rocks Look glassy Have air pockets Have interlocking crystals Name the igneous rocks on the following slides.
Chapter 4 section 3. Rocks that have been changed because of changes in Heat Pressure Or the presence of hot, watery fluids Can be formed from igneous,
Metamorphic Rocks Change is Good. Metamorphic Rocks Formed from intense heat and pressure!
BIG Idea ► Most rocks are formed from pre-existing rocks through external and internal geologic processes.
Quiz Get out you ESRT and a piece of paper The following questions are from your ESRT. You’ll have a minute per question…
Rocks and Minerals. Types of Rocks Igneous Rock Sedimentary Rock Metamorphic Rock.
Metamorphic Rocks. What is a metamorphic rock? Rock formed from other rocks as a result of intense heat, pressure, or chemical processes. There are.
Metamorphic Rocks “If something is gneiss, don’t take it for granite.”
Metamorphic Rocks. Questions What are metamorphic rocks? What processes are involved in forming metamorphic rocks?
Metamorphic Rock Chapter 4 Section 4. Metamorphic Rock Rock that has changed its form Change is caused by heat and pressure Changes can occur in the rock’s:
Are rocks that have been altered or have undergone change.Metamorphic rocks begin as either igneous, sedimentary or another metamorphic rock…we call the.
Metamorphic Rock Metamorphism: Changing of one type of rock to another by: Heat Pressure Chemical reactions Metamorphism makes rocks stronger or more.
Metamorphic Rocks Rocks & Minerals Notes: Page 10.
Classifying Rocks Igneous rocks are classified according to their origin, texture, and mineral composition. Origin Did it harden inside the earth or.
Metamorphic Rocks. Transforming Rocks Rocks change because of changes in temperature and pressure, or the presence of hot, watery fluids. Mineral grains.
Metamorphic Textures Metamorphism literally means to “change form.” The degree of metamorphism is reflected in the rocks texture and mineralogy. Two.
Metamorphic Rock. Definition of Metamorphic Rocks Metamorphic rocks are formed when existing rocks are changed into a new rock because of heat, pressure,
Metamorphic Rocks. The Rock Cycle If you bury a rock deep enough, it will melt (IGNEOUS) Not so deep, a rock will become lithified (SEDIMENTARY) At conditions.
Metamorphic Rocks. Metamorphic rocks form due to increased heat, increased pressure, and hydrothermal solutions – Heat – comes from 2 sources: magma and.
Metamorphic Rocks A metamorphic rock is a pre-existing rock that has changed due to its exposure to tremendous heat, pressure and/or mineral fluids.
February 2012 Interactives. The Rock Cycle. The Rock Cycle.
Metamorphic Rocks A metamorphic rock is…. Formation of Metamorphic Rocks Metamorphism – or the process of making metamorphic rock – takes place within.
Metamorphic Rocks: Windows into the Earth’s Interior Metamorphic rocks form by the alteration of pre-existing rocks in the solid state by heat, pressure,
Uniformitarianism: 1795 – James Hutton “the present is the key to the past” we can learn about Earth’s history by studying present processes.
Rocks and the Rock Cycle Igneous, Sedimentary, Metamorphic.
The process by which existing rock is changed by heat and pressure is called metamorphism Original sedimentary or igneous rock is known as parent rock.
Metamorphic Rocks. Metamorphic Rocks: form when heat and/or pressure change pre-existing rocks. – Metamorphism: the process of forming metamorphic rocks.
Metamorphic rocks can be classified into one of three sub-families: Unfoliated - Foliated - Deformed - A banded rock splitting more or less evenly into.
Metamorphic Rocks. Rock Cycle Objectives 14 – Describe the types of changes associated with metamorphic rocks. 15 – Contrast regional and contact metamorphism.
Metamorphism Surface Lithification Melting High temperatures come from: Deep Burial Igneous Intrusions High temperatures come from: Deep Burial Igneous.
Igneous rocks ► Crystallize from a molten rock: magma ► Magma: liquid rock beneath earth’s surface ► Lava: liquid rock above earth’s surface ► Igneous.
Chapter 4: Rocks Section 3: Metamorphic Rocks Study Guide.
Metamorphic Rock Examples Quartzite Tough building material Anthracite Coal High quality, creates lots of energy when burned.
SC Standard Explain how igneous, sedimentary and metamorphic rocks are interrelated in the rock cycle.
Rocks & The Rock Cycle. Rocks vs Minerals ROCKS –SOLID MIXTURE OF MINERALS –MAY BE ORGANIC MINERALS –NATURALLY FORMED OF ELEMENTS OR COMPOUNDS –INORGANIC.
Chapter 4 Section 3 METAMORPHIC ROCKS. You will learn: Describe the conditions in Earth that cause metamorphic rocks to form Classify metamorphic rocks.
Metamorphism and Metamorphic Rocks A. Metamorphic rocks: Form at conditions between igneous and sedimentary rocks.
Formation of Metamorphic Rocks Rocks that have changed because of changes in temperature and pressure or the presence of hot watery fluids are called metamorphic.
2014. A mineral is a naturally formed, inorganic solid that has a definite crystalline structure.
Aim: Aim: What are metamorphic rocks? Metamorphic Rocks I. Metamorphic Rocks – rocks that have been exposed to great heat and pressure. A. Dynamic Metamorphism(Regional.
Metamorphism is the changes in a rock that result in the formation of metamorphic mineral assemblage. Metamorphic rocks may have foliation in response.
Metamorphic Rocks How a little bit of heat & pressure transform rocks!
