Geology 101 exam 1 (100 questions)

Wegener's idea of continental drift was rejected by geologists because:

• there was strong evidence that continents did not move
• he had no valid mechanism that would cause continents to move
• he had little evidence supporting the existence of a supercontinent
• the apparent fit of coastlines is blurred when the margins are defined by the

edges of continental shelves rather than sea level

• he had no valid mechanism that would cause continents to move

For this river, which of the following statements is true?

• All of the possible answers are correct.
• If the stream flow were reversed, the locations of point bars and cut banks

would remain the same.

• The streambed at X is at a lower elevation than the streambed at Y.
• If erosion at X and Y were to cut off the meander between them, an oxbow lake

would be created.D

The total sediment load of a stream includes

Choose one:

• bed load. 1 / 4

pg. 2

• dissolved load.
• suspended, bed, and dissolved loads.
• suspended load.

C

Earth's magnetic field is generated by:

• the flow of the liquid inner core
• the flow of the liquid outer core
• the convective flow of the mantle
• magnetic minerals within the crust
• the flow of the liquid outer core

The Wadati-Benioff zone is a belt of earthquakes found:

• within an otherwise stable continental interior
• within an overriding plate at a subduction zone
• within a downgoing plate at a subduction zone
• along mid-ocean ridges
• within a downgoing plate at a subduction zone

As compared to the rocks that make up the crust, Earth as a whole is:

• considerably more dense
• considerably less dense
• slightly less dense
• about the same density
• considerably more dense

Identify the statement that is true about landscapes on Mars.

Choose one:

• Mars no longer has a hydrologic cycle because all water and/or ice is now gone

from the surface.

• Olympus Mons is an extinct hot-spot volcano on Mars and is the highest

mountain in the Solar System.

• Similar to the Earth, Mars has mountain belts formed by plate tectonics.
• Because Mars has no atmosphere, wind erosion does not affect the surface of

the planet.B Which of the following statements is true about lakes?

Choose one:

• The bottom of a lake bed represents the groundwater table in the region. 2 / 4

pg. 3

• The surface of a lake corresponds to the surface of the groundwater table

nearby.

• A lake is surface water; it is not associated with groundwater.
• The presence of a lake indicates a lack of groundwater in a region.

D Which of the following is a type of mountain (alpine) glacier?

Choose one:

• continental shelf
• continental glacier
• ice shelf
• valley glacier

D A glacier can have only one of which of the following types of moraines?

Choose one:

• end
• lateral
• medial
• terminal

D Select the statement that best describes glacial movement.

Choose one:

• Glaciers are a mixture of ice and water; they flow as a slurry of icy water.
• Glaciers flow like an extremely viscous fluid by undergoing internal plastic

deformation.

• Glaciers move as a rigid block by sliding along the ground surface.
• Glaciers are solid ice; they do not move.

B A typical longitudinal profile of a stream

Choose one:

• has a constant slope from its source to its mouth.
• illustrates that a stream's gradient is steeper near its headwaters than near its

mouth.

• shows a cross section of the stream from bank to bank at one particular site.
• shows that most streams flow down low slopes near their headwaters, and flow

down steep valleys near their mouths. 3 / 4

pg. 4 B

Identify the true statement. Choose one:

• Glaciers can undergo ablation by melting, sublimation, or calving.
• Glaciers always retreat when they reach an elevation of less than 5,000 feet.
• The zone of ablation is the area of the glacier where each year more snow falls

than melts.

• When a glacier retreats, its ice contracts and flows back toward the glacier's

point of origin.A According to Milutin Milanković, which of the following caused glacial- interglacial cycles during the Pleistocene?

Choose one:

• variations in the shape of the Earth's orbit
• variations in ocean temperature
• sunspot cycles
• increased amounts of volcanic ash

A

Marine magnetic anomaly belts run parallel to:

• mid-ocean ridges
• continental coastlines
• fracture zones
• continental shelves
• mid-ocean ridges

The above cross section of the Earth from surface to center (left to right) shows the

following internal layers in correct relative size labeled from A to E:

*See question 2 on Exam 1 for diagram

• Asthenosphere, Lithosphere, Crust, Mantle Core
• Crust, Upper Mantle, Lower Mantle, Outer Core, Inner Core
• Soil, Transition Zone, Upper Mantle, Lower Mantle, Core
• Lithosphere, Upper Mantle, Transition Zone, Lower Mantle, Core
• Crust, Upper Mantle, Lower Mantle, Outer Core, Inner Core

Marine magnetic anomaly belts are widest when and where:

• continents are joined to form supercontinents
• sea-floor spreading rates are relatively rapid
