Multiple-Choice Quiz
Our Multiple-Choice Quiz will test your knowledge of the basic concepts and ideas offered in Chapter 14. By successfully reviewing these concepts, you will reinforce your comprehension of these geographic ideas.

This activity contains 20 questions.

	Plate tectonic processes include all of the following, except what?   creation of new oceanic crust at mid-ocean ridges ocean floor spreading crustal rearrangement subduction of heavier (more dense) continental crust under lighter (less dense) oceanic crusts

	An anticline is what?   a geologic structure in which rock strata dip inward toward a common central linear area of rock depression a structural landform that occurs mostly in arid environments a structural landform that is restricted to mountains a geologic structure in which rock strata dip outward from a common central linear area of uplift none of the above

	A batholith is what?   a moderate size pluton that forms just below the Earth's surface a massive pluton that cools slowly usually generates fine textured igneous rocks the first stage in the formation of metamorphic rocks none of the above

	Divergent plate boundaries are characteristic of what?   lateral motions of plates all plate boundaries seafloor spreading centers collision zones of compression between plates none of the above

	The Himalayas and the Alps are the result of what?   subduction ocean plate/continental plate collision ocean plate/ocean plate collision continental plate/continental plate collision none of the above

	Volcanic activity in the Hawaiian Islands   results from magma intrusion through ocean crust that has been moving across the top of a hot-spot magma convection flow. is illustrative of magma generate at a mid-ocean rift zone. produces andesite-type volcanoes. is illustrative of magma generated by plate subduction. is none of the above.

	Pangaea   is a rift valley in eastern Africa where a new ocean is forming. is the name for the former super continent thought to have broken apart into several crustal plates (representing the modern continents). is the period of geologic history that predates continental life (biological) forms. is the part of California west of the San Andreas Fault where the continental crust is moving into the Pacific Ocean. is none of the above.

	A laccolith   is illustrated by the local hot-spot landforms of the Hawaiian Islands. usually cools more rapidly than a batholith. usually is larger in size than a batholith. represents a place where extrusive igneous rocks form. is none of the above.

	In a strike-slip fault, the movement   is entirely horizonal. is entirely upward. is entirely downward. is both upward and horizontal. is none of the above.

	Diastrophism   refers to the deformation of Earth's crust by bending or breaking in response to great pressures exerted either from below or from within the crust. refers to the boundaries between crustal plates. refers to all processes in which magma moves from the Earth's surface to or near the surface. refers to a discredited theory of continent formation. is none of the above.

	Horst and graben topography is associated with _____ faults.   normal reverse overthrust strike-slip overslip

	_____ is the technique used to date and study the ocean floor, which was fundamental in leading to the general acceptance of plate tectonics.   plasticity isostasy paleomagnetism paleoalignment pangaeation

	The youngest rocks at the Earth's surface tend to be located _______.   on major mountain range where the crust is thickest near the midocean ridge near ocean trenches where subduction is occurring the to shield region of North America

	The feature in the foreground of this photograph is a(n) _____. [Photo Source]   syncline anticline monocline horst graben

	The Black Hills, South Dakota, is a dome-shaped feature formed over a ____.   volcano dike sill laccolith mesa

	Shiprock, New Mexico, formed from lava solidifying in the "throat" of a volcano. Today, the exposed sharp spire is called _____.   a batholith a dike a vocanic neck a sill none of the above

	Mount Fuji, Mount Rainier, and Mount Shasta are all   composite volcanoes. lava domes. shield volcanoes. cinder cones. exposed batholiths.

	A caldera forms   over a batholith. from the collapse of a laccolith. from the intrusion of a dike. from the collapse of a volcanic crater. none of the above.

	A block uplifited between two parallel faults is a   plateau. horst. graben. mesa. caldera.

	The Columbia plateau   is a graben. was built of flood basalts. formed from a batholith. is a result of an eroded anticline. is none of the above.
