What makes up the lithosphere?

• upper mantle

• continental crust

• crust and upper mantle

• oceanic crust and continental crust

The data about two crustal samples are shown in the table below. Which must be TRUE?

• Both Sample A and Sample B are oceanic crust

• Both Sample A and Sample B are continental crust

• Sample A is continental crust, while Sample B is oceanic crust

• Sample A is oceanic crust, while Sample B is continental crust

Which refers to the smaller sections of Earth’s lithosphere?

• asthenosphere

• crust

• mantle

• plate

Geologic phenomena occur because the entire lithosphere is broken into numerous segments called plates that move slowly and continuously and interact with each other. What does this statement refer to?

• Plate Tectonic Theory

• Continental Drift Theory

• Continental Shift Theory

• Sea Floor Spreading Theory

Which is a secondary tectonic plate?

• African Plate

• Arabian Plate

• Eurasian Plate

• Indo-Australian Plate

Plates A and B are classified as primary plates while C and D are classified as secondary plates. What must be TRUE about these plates?

• Plates A and B are larger plates while Plates C and D are smaller plates

• Plates A and B are smaller plates while Plates C and D are larger plates

• Plates A and B are denser plates while Plates C and D are less dense plates

• Plates A and B are less dense plates while Plates C and D are denser plates

What term refers to the edges that separate the tectonic plates from one another?

• Lithosphere-Asthenosphere boundary

• Mohorovicic discontinuity

• Pangaea

• Plate Boundary

Which type of seismic wave is recorded first in a seismic station?

• P-wave

• S-wave

• Love wave

• Rayleigh wave

Which statement CORRECTLY describes a primary wave?

• It is a transverse wave

• It is faster than a secondary wave

• It travels through solid materials only

• It is observed only at the ground surface

Which statement CORRECTLY describes the behavior of S-waves?

• S-waves travel faster than P-waves.

• S-waves can only travel through solids.

• S-waves are the first to be detected by seismographs.

• S-waves can travel through both solids and liquids.
