Chapter 11 Mountain Building Practice Test

Front

What is an accumulation of different sedimentary and metamorphic rocks combined with scraps of ocean crust called?

Back

An accretionary wedge.

Front

Faults are generally closely associated with which geological feature?

Back

Monoclines.

Front

How do anticlines and synclines contribute to mountain building?

Back

By folding rock layers.

Front

Once their strength is exceeded, rocks near the surface behave like what?

Back

Glass objects.

Front

Under which conditions do rocks exhibit ductile deformation?

Back

High pressures.

Front

What is a dome in geological terms?

Back

A dome is a type of fold that is convex upward, resembling an upside-down bowl.

Front

Define a volcanic island arc.

Back

A volcanic island arc is a chain of volcanic islands formed at a convergent plate boundary, where an oceanic plate subducts beneath another oceanic plate.

Front

What are fault-block mountains?

Back

Fault-block mountains are formed through faulting, where blocks of the Earth's crust are lifted or tilted.

Front

What is the difference between anticlines and synclines?

Back

Anticlines are upward folds in rock layers, while synclines are downward folds.

Front

What role do glaciers play in mountain erosion?

Back

Glaciers erode mountains by scraping and carving the landscape as they move.
