A white high school student is worried about her upcoming orchestra concert, but calms herself down by thinking, "We have five Chinese students playing violin and viola. They've got the Chinese advantage in music, so the concert will be just fine." This is an example of

Prejudice

Explanation:

Prejudice is a negative preconception of of an individual that often leads to unfavourable attitude towards such individual. Prejudice may arise from a baseless stereotyped beliefs about an individual's gender, social class, age, beliefs, values, religion, sexuality, race/ethnicity, language, political affiliation, nationality, beauty, occupation, education or other personal characteristics that can influence (especially negatively) how a person behaves towards such individual.

From this question, the white student has prejudiced opinion about the concert based on the ethnic background of the Chinese students

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
