Exam 9: Mountains

Where two continents collide, one continent is forced under the other in a process called __________.

A slip is:

A subduction complex contains slices of continental crust scraped from the top of a subducting plate.

Factors determining how a rock responds to stress are:

Compression is common at:

A cool rock near the Earth's surface is more likely to __________ than a similar rock that is hot and under great pressure.

A normal fault occurs as a result of:

A sedimentary basin between a trench and an island arc is called a __________.

A thrust fault is a special type of normal fault that is nearly horizontal.

A circular or elliptical synclinal structure is called a/an __________.

A fold in a rock indicates that the rock:

Island arcs are abundant in the Pacific Ocean.

The sides of a fold are called synclines.

The term __________ refers to the process of mountain building.

The higher the pressure, the more likely that a rock will undergo:

The Andes Mountains were formed by convergence of a plate carrying __________ crust with a plate carrying __________ crust.

Rock that is caught at the junction of two converging plates is deformed by __________ stress.

Where two continental plates converge, compressional stress squeezes rocks, forming folds and reverse and thrust faults.

Normal faults, grabens, and horsts are common:

The underthrusting of __________ beneath Tibet caused the rise of the Himalayas.
