Concept #4 Quiz
Choose the best possible answer to the following questions about Key Concept 4 "Metamorphic environments."

This activity contains 6 questions.

In what ways do rocks become hotter, so that they can metamorphose?

subduction, continental collision, heating from magma cooling subduction, heating from magma cooling, diagenesis burial into the mantle, subduction, mid-ocean ridge proximity continental subduction, heating from magma cooling

Match the name of the metamorphic environment with the appropriate description:

Using the pull-down menus, match each item in the left column to the corresponding item in the right column.


	largest volume of metamorphic rocks, associated with mountain belts and stable continental shields

	tektites form by a sudden extreme increase in energy, including very high pressure

	metamorphic aureoles form around cooling magma bodies like plutons and dikes

	low-grade, subsiding basin, shallow depth processes

	metasomatism changes a rock’s composition by exchanging soluble ions

	breccia, gouge, and mylonites form

2.1 impact metamorphism

2.2 fault zones metamorphism

2.3 burial metamorphism

2.4 regional metamorphism

2.5 hydrothermal metamorphism

2.6 thermal metamorphism

Which of the following best describes a condition of contact metamorphism?

Heat is generated by shearing and mechanical movements along breaks.Pressure is fairly low, the rock is in the upper part of the crust, and heat is supplied from a nearby magma body. Depth is fairly shallow, but temperature and pressure are so high that the rocks begin to partially melt. Pressure is very high, the rock is deeply buried, and temperature is raised by the Earth’s internal heat.

Match the appropriate metamorphic environments with the labels of the diagram.

The letters A through D appear on an image associated with this question.

4.1 regional metamorphism

4.2 burial metamorphism

4.3 low-grade metamorphism

4.4 high-grade metamorphism

Which of the following best describes a condition of regional metamorphism?

Depth is fairly shallow, but temperature and pressure are so high that the rocks begin to partially melt. Pressure is fairly low, the rock is in the upper part of the crust, and heat is supplied from a nearby magma body. Heat is generated by shearing and mechanical movements along breaks.Pressure is very high, the rock is deeply buried, and temperature is raised by the Earth’s internal heat.

Which of the following best describes a condition of fault-zone metamorphism?

Depth is fairly shallow, but temperature and pressure are so high that the rocks begin to partially melt. Heat is generated by shearing and mechanical movements along breaks. Pressure is very high, the rock is deeply buried, and temperature is raised by the Earth’s internal heat. Pressure is fairly low, the rock is in the upper part of the crust, and heat is supplied from a nearby magma body.
