Bell Work: 10/20/14 Write the answer and explain why the answer you chose is correct (justify your answer). What type of rock is most likely formed by process 3?

Real-life application! What am I pointing to? What is the process called that forms them?

Objectives 25. Metamorphic Rock Notes Identify the major processes that drive the rock cycle (SPI ). How are metamorphic rocks formed? How are the composition, heat, and pressure related to the texture of metamorphic rock? What is the difference between foliated and nonfoliated metamorphic rocks? Label a diagram that depicts the three different rock types (SPI ).

Metamorphic Starbursts Group Discussion: Rip your Starburst in half and share it with someone in your group who has a different color Starburst. Stick the two pieces together and wrap them back up in your Starburst wrapper. Explain to your elbow partner how the individual pieces of starbursts stuck together are like sedimentary rock. What does the word “metamorphosis” mean? We will look at more questions towards the end of class…

Metamorphic Rocks: Rocks that Change Metamorphic comes from the Greek words meta and morph. Meta means “change” and morph means “form”. So we get metamorphic meaning to change form.

Metamorphic Rock: Origins of Metamorphic Rock Rocks can also go through a process called metamorphism, which means to ____________. ___________ _______ are rocks in which the structure, texture, or composition of the rocks have changed. All three types of rocks can go through metamorphism or can be changed by ______, _________, or a combination of both. change form rocks Metamorphic heat pressure

Metamorphic Rock: Two Kinds of Metamorphism ___________ ________________occurs when magma intrudes or forces its way into existing rock. The heat of the magma bakes the surrounding rocks causing them to change. ___________ ________________ by contrast takes place over large areas deep within Earth’s crust. Regional metamorphism is associated with mountain building. Contactmetamorphism Regional metamorphism

Metamorphic Rock Textures of Metamorphic Rocks Textures of metamorphic rocks depend on composition of the rock and the amount of heat and pressure that is applied to the rock. __________ = mineral grains arranged in bands or planes (straight lines). Look at pg ____________ = mineral grains are not arranged in bands or planes Examples of metamorphic rocks: Foliated Nonfoliated Marble Gneiss

Rock Classification In the T-chart on your notes, lets categorize the rock samples as Foliated Metamorphic Rocks or Nonfoliated Metamorphic Rocks. Pay careful attention to how the mineral grains are arranged in the rocks (bands or not). Write the names of the rocks on the T- chart under the categories.

Question Challenge: How could #14, Amphibolite, be categorized both foliated and nonfoliated?

Real World Uses of Metamorphic Rocks Marble Slate

Metamorphic Starbursts Group Discussion: Describe how your starburst metamorphoses when heat and pressure are applied to them. How is this starburst activity related to metamorphic rock?
