Question 9

An elongated region of the crust that has been deformed by continental collision is known as a(n)_____.
A)anticline
B)strike
C)graben
D)axis
E)orogen

Accepted Answer

An orogen refers to a long, narrow mountain chain that has been formed by the folding and faulting of the Earth's crust due to the collision of two tectonic plates. It is a result of the convergent boundary, where two plates move towards each other and compress the crust, leading to the formation of mountain ranges. Therefore, an orogen is the best choice for an elongated region of the crust that has been deformed by continental collision. Anticline describes an upward fold in rocks, and graben refers to a depressed block of land between two parallel faults. Strike is a term that defines the orientation of a rock or fault surface in a particular direction. None of these terms describe an elongated region of the crust that has been deformed by continental collision.

Question 10

A _____ map shows the locations,kinds,and orientation of rock units.
A)topographic
B)geologic
C)bathymetric
D)political
E)road

Accepted Answer

Geologic maps are specifically designed to show the locations, kinds, and orientations of rock units. Topographic maps show the elevation and relief of an area, bathymetric maps show the underwater topography, political maps show the boundaries and territories of countries or regions, and road maps show the road networks and highways.

Question 11

Lines of equal elevation are called _____ lines.
A)isostasy
B)basin
C)contour
D)orogen
E)shear

Accepted Answer

Lines of equal elevation are called contour lines, which are used in topographic maps to show the height and shape of the land surface.

Question 12

A _____ is a fracture in rock along which movement has occurred.
A)tension
B)flanks
C)syncline
D)shear
E)fault

Accepted Answer

A fault is a fracture or break in rock along which there has been movement, and it is typically caused by tectonic activity. The other choices do not accurately describe a fracture or break in rock with movement.

Question 13

_____ deformation is a temporary change in the shape or volume of a rock that rebounds after the stress is removed.
A)Buoyant
B)Ductile
C)Shear
D)Elastic
E)Lateral

Accepted Answer

Elastic deformation is a temporary change in the shape or volume of a rock that rebounds after the stress is removed. This means that the rock returns to its original shape or volume once the stress is released.

Question 14

Which of the following terms best describes a local steepening in otherwise uniformly dipping strata?
A)fold
B)monocline
C)microfractures
D)axis
E)horst

Accepted Answer

A monocline is a geological feature where there is a local steepening in otherwise uniformly dipping strata. It represents a step-like fold in rock layers where all layers are inclined in the same direction, but with one part of the sequence having a steeper inclination.

Question 15

According to the figure below,which of the following shows high confining pressure? 
A)A
B)B
C)C
D)A and C
E)B and C

Accepted Answer

The answer of According to the figure below,which of the...

Question 16

Which of the following best describes a bend or a warp in a layered rock?
A)fold
B)flank
C)fault
D)tension
E)axis

Accepted Answer

A bend or a warp in a layered rock is known as a fold.

Question 17

Tensional faults are also called _____ faults.
A)thrust
B)left-lateral strike-slip
C)right-lateral strike-slip
D)normal
E)reverse

Accepted Answer

Tensional faults are also known as normal faults. These faults occur when rocks are pulled apart, causing the hanging wall to move downward relative to the footwall.

Question 18

Which of the following terms best describes an area of continental crust that has remained undeformed for a very long time?
A)fault
B)craton
C)relief
D)stress
E)anticline

Accepted Answer

A craton is a stable area of continental crust that has not undergone significant deformation for a long period of time, typically billions of years.

Question 19

Which of the following geologic structures has the youngest rocks in the middle?
A)syncline
B)anticline
C)fault
D)craton
E)dome

Accepted Answer

In a syncline, the youngest rocks are typically found in the center, with older rocks exposed on the flanks. This is due to the way layers of sediment accumulate and are subsequently folded, with the newer layers being deposited last and thus ending up on the inside of the fold.

Question 20

In the figure below,which part of the horst and graben structure is bound by normal faults,resulting in a down-dropping? 
A)horst
B)graben
C)fault plane
D)tension plane
E)none of the above

Accepted Answer

Graben is a down-dropped block of land that is surrounded by parallel normal faults. This is in contrast to a horst, which is an upthrown block of land surrounded by parallel normal faults.
