Quiz 2 grade 11

What is metamorphism?

• The process by which rocks are formed from molten lava.

• The process by which the structure and composition of rocks are changed due to high temperature, pressure, or chemical reactions.

• The process by which rocks are broken down into smaller pieces.

• The process by which rocks are eroded by wind and water.

Name the three types of metamorphism.

• Thermal metamorphism, tectonic metamorphism, and chemical metamorphism

• Igneous metamorphism, sedimentary metamorphism, and metamorphic metamorphism

• Contact metamorphism, regional metamorphism, and cataclastic metamorphism

• Static metamorphism, kinetic metamorphism, and elastic metamorphism

What is foliation in metamorphic rocks?

• Formation of cracks and fractures in the rock

• The process of erosion wearing away the rock surface

• The presence of fossils within the rock

• An alignment of mineral grains in a metamorphic rock

What are the agents of metamorphism?

• wind, water, and ice

• heat, pressure, and chemically active fluids

• gravity, magnetism, and radiation

• plants, animals, and fungi

Which type of metamorphism occurs due to the heat and pressure associated with igneous intrusions?

• contact metamorphism

• hydrothermal metamorphism

• dynamic metamorphism

• regional metamorphism

Which type of metamorphism occurs due to the heat and pressure associated with tectonic plate collisions?

• contact metamorphism

• dynamic metamorphism

• burial metamorphism

• regional metamorphism

cataclastic metamorphism happen due to ___________ pressure.

• uniform pressure

• directed pressure

• barometric pressure

• Non- of the above

What are metamorphic rocks?

• Rocks that are formed by the accumulation of sediments.

• Rocks that have been changed from their original form by heat, pressure, or chemical processes.

• Rocks that are made up of only one mineral.

• Rocks that are formed by volcanic activity.

What are non-foliated metamorphic rocks?

• Non-foliated metamorphic rocks are rocks that have a layered or banded appearance.

• Non-foliated metamorphic rocks are rocks that are formed from sedimentary rocks.

• Non-foliated metamorphic rocks are rocks that are formed from igneous rocks.

• Non-foliated metamorphic rocks are rocks that do not have a layered or banded appearance.

low grade metamorphism heat range from______ to_____ ⁰C.

• 200- 400

• 100- 600

• 500- 800

• 100-500
