Rock Quiz: Characteristics of Metamorphic Rocks

What is the process by which metamorphic rocks are formed?

• Heat, pressure, and chemical reactions

• Volcanic activity, sedimentation, and erosion

• Erosion, deposition, and compaction

• Freezing, thawing, and weathering

What are the two main factors that contribute to the formation of metamorphic rocks?

• Wind and water

• Color and texture

• Time and erosion

• Temperature and pressure

Name one example of a common metamorphic rock.

• Marble

• Sandstone

• Limestone

• Granite

What is the difference between foliated and non-foliated metamorphic rocks?

• Foliated rocks are formed from lava, while non-foliated rocks are formed from sedimentary rocks.

• Foliated rocks have a banded or layered appearance, while non-foliated rocks do not.

• Foliated rocks are always white in color, while non-foliated rocks are always black.

• Foliated rocks are only found in deserts, while non-foliated rocks are only found in mountains.

How does the texture of a metamorphic rock differ from that of an igneous rock?

• Crystalline and glassy

• Smooth and polished

• Porous and lightweight

• Layered or banded

What are the main characteristics of a schist rock?

• Layered texture and presence of granite and basalt

• Foliated texture and presence of minerals like mica, chlorite, and talc

• Rough texture and presence of limestone and sandstone

• Smooth texture and presence of quartz and feldspar

What is the process of recrystallization in metamorphic rocks?

• Formation of igneous rocks

• Erosion by wind and water

• Formation of new crystals due to heat and pressure

• Deposition of sedimentary rocks

How do metamorphic rocks differ from sedimentary rocks?

• Metamorphic rocks are formed from organic remains

• Metamorphic rocks are formed from molten lava

• Metamorphic rocks are formed from wind-blown sediments

• Metamorphic rocks are formed from existing rocks that have been altered by heat, pressure, or chemical processes.

What are the main agents of metamorphism?

• Wind, water, and sunlight

• Gravity, erosion, and deposition

• Heat, pressure, and chemically active fluids

• Volcanic eruptions, earthquakes, and tsunamis

What are the main types of metamorphism?

• Igneous metamorphism and sedimentary metamorphism

• Volcanic metamorphism and plutonic metamorphism

• Chemical metamorphism and physical metamorphism

• Regional metamorphism and contact metamorphism
