Metamorphic Rock

What does the name “metamorphic” mean?

• black rock

• changed shape

• volcanic rock

• changed variable

What is the definition of a metamorphic rock?

• a volcanic rock that has been submerged in water

• a rock that has undergone chemical and/or physical changes in the solid state

• a rock that turned a different color after being exposed to light

• a concrete based rock with ruby gems in it

What are the two main types (scales) of metamorphism?

• Contact Metamorphism (small scale) and Regional Metamorphism (large scale)

• Contact Metamorphism (small scale) and Realism Metamorphism (large scale)

• Crate Metamorphism (small scale) and Regional Metamorphism (large scale)

• Pressure (small scale) and Heat (large scale)

What are the factors that make an igneous or sedimentary rock turn into a metamorphic rock?

• Heat and Harsh Weather

• Melting Does

• Heat, Contact and Weathering

• Heat, Pressure and Chemical Reactions with Hot Fluids

What are the three ways that a rock can physically change in the solid state during metamorphosis?

• reorientation of rod or plate shaped minerals, recrystallization of minerals resulting in less but larger grains, and creation of god like ideologies

• reorientation of rod or plate shaped minerals, recrystallization of minerals resulting in less but larger grains, and creation of new minerals

• melt, change in shape and more rocks will be made

• crystals separate , more rocks will be made and they will melt

What are the two main types of metamorphic rock textures?

• Foliated and Non-Felt Tipped

• Combust and Combustion

• Natural and Unnatural

• Foliated and Non-Foliated

What are the names of foliated rocks that have: microscopic, small (almost to barely visible), and large (visible) mica grains?

• slate, pyrite, gneiss

• gneiss, sandstone, basalt

• slate, phyllite, schist

• granite, shale, diorite

What is the name of the foliated rock with a dark/light banded pattern?

• gneiss

• basalt

• granite

• slate

What do you call a rock that partially melted?

• Magnitite

• Migmatite

• Marble

• Mafic

What are the names of the two most common non foliated metamorphic rocks, what minerals make up each, what is the most common parent rock for each, and what physical tests could you use to distinguish them?

• Quartz (quartz) and Mica (mica), Sandstone, hardness and HCl test

• Marble (calcite) and Quartzite (quartz), Limestone, hardness and HCl test

• Pyrite (quartz) and Sandstone (sediment), Limestone, hardness and breakage test

• Schist (k-feldspar) and Gneiss (quartz), Sandstone, hardness and HCl test
