Kirk is wearing a costume and is out with a group of friends on Halloween. Although Kirk is not usually a mean or aggressive person, he agrees to throw eggs at passing cars and steal candy from little kids who are trick-or-treating. Which of the following best explains Kirk's behavior in this situation?
A. Kirk's friends are providing a descriptive norm for behavior.
B. Because he is in a crowd, he is experiencing deindividuation.
C. Because other people are around, social facilitation is occurring.
D. Kirk has privately accepted that this is how people normally behave.

The correct answer is B. Because he is in a crowd, he is experiencing deindividuation.

Explanation:

Because kirk is in a crowd, he is experiencing deindividuation which refers to a loss of self awareness and self control in group situations that gives the tendency to exert less effort in achieving a goal and it occurs when a person's identity with a group overrides their own identity and self awareness.

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)
