1Which mechanical layer of Earth's interior is composed of rigid, brittle rock and includes both the crust and the uppermost solid mantle?
A.Lithosphere
B.Asthenosphere
C.Mesosphere
D.Outer Core
Explanation: The lithosphere is the rigid, brittle outermost mechanical layer of Earth, comprising the crust and the brittle upper section of the mantle down to a depth of roughly 100 km.
2Which type of seismic body wave travels fastest through Earth's interior and can propagate through both solid and liquid media?
A.Love waves
B.Primary (P) waves
C.Secondary (S) waves
D.Rayleigh waves
Explanation: Primary (P) waves are compressional longitudinal body waves that travel fastest through Earth and can propagate through solids, liquids, and gases because fluid media resist compression.
3The Mohorovičić discontinuity (Moho) marks the seismic boundary between which two compositional layers of Earth?
A.Mantle and outer core
B.Outer core and inner core
C.Crust and mantle
D.Upper mantle and lower mantle
Explanation: The Mohorovičić discontinuity (Moho) is the boundary separating Earth's crust from the underlying mantle, marked by a sudden increase in P-wave velocity.
4At which type of plate boundary is new oceanic lithosphere continuously created by mantle upwelling and basaltic magmatism?
A.Transform boundary
B.Oceanic-continental convergent boundary
C.Continental collision boundary
D.Divergent boundary
Explanation: Divergent boundaries (mid-ocean ridges) experience tensional stress where tectonic plates move apart, allowing decompression melting of the mantle to form new oceanic crust.
5What type of geological fault is produced by tensional stress, resulting in the hanging wall moving downward relative to the footwall?
A.Normal fault
B.Reverse fault
C.Thrust fault
D.Strike-slip fault
Explanation: Normal faults form under crustal tension where the hanging wall block moves downward relative to the footwall along an inclined fault plane.
6Which foliated metamorphic rock represents the lowest grade of regional metamorphism derived from a shale protolith?
A.Granulite
B.Slate
C.Schist
D.Gneiss
Explanation: Slate is a fine-grained foliated metamorphic rock formed under low temperature and low pressure conditions from shale or mudstone protoliths.
7Plutonic (intrusive) igneous rocks cool slowly deep beneath Earth's surface, resulting in which typical texture?
A.Porphyritic with glass
B.Vesicular
C.Phaneritic (coarse-grained)
D.Aphanitic (fine-grained)
Explanation: Slow cooling of magma deep underground provides ample time for mineral crystals to grow large, producing a phaneritic (coarse-grained) texture.
8The San Andreas Fault system in California is a classic geological example of which plate tectonic boundary?
A.Subduction zone convergent boundary
B.Continental rift divergent boundary
C.Back-arc spreading basin
D.Right-lateral strike-slip transform boundary
Explanation: The San Andreas Fault is a major transform fault boundary where the Pacific Plate slides horizontally right-laterally past the North American Plate.
9Why does an S-wave shadow zone exist on the side of Earth opposite a seismic hypocenter (between 104° and 180° angular distance)?
A.S-waves cannot propagate through the liquid outer core because liquids lack shear strength
B.S-waves are refracted upward by the crust-mantle Moho boundary
C.S-waves convert entirely into P-waves at the core-mantle boundary
D.S-waves are absorbed by partial melting in the asthenosphere
Explanation: S-waves are transverse shear waves that require rigid shear strength to propagate. Because the outer core is liquid iron-nickel, S-waves cannot pass through it, creating a large S-wave shadow zone beyond 104°.
10What physical property change causes P-wave paths to refract sharply downward when entering Earth's liquid outer core from the lower mantle?
A.A sudden decrease in temperature that crystallizes the outer mantle
B.A abrupt decrease in seismic wave velocity due to lower bulk modulus and shear modulus in the liquid outer core
C.A dramatic increase in rock density that doubles P-wave velocity
D.A change from longitudinal compressional motion to transverse shear motion
Explanation: As P-waves enter the liquid outer core at the Gutenberg discontinuity (~2,900 km depth), their velocity drops sharply from ~13.7 km/s to ~8.1 km/s because liquids have zero shear modulus ($G=0$), causing strong downward refraction.
