As martha walks into the college library, she sees a friend and whispers "hi" as she passes. her whispering is likely in concordance with the "rules," or expectations, for appropriate behavior in a particular social situation. such expectations are referred to in social psychology as: ) person perception. b) social perception. c) stereotype rules. d) social norms.

The correct answer is letter D

Social norms are prescriptions of behavior. The concept of social norm corresponds to social expectations about what is an appropriate or correct behavior. The interaction between individuals does not follow chance; it is in social norms that the necessary basis for interaction and general human social action is found.

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)
