Several months after watching a science fiction movie about space travel and alien abductions, Margo began to remember that aliens had abducted her and had subjected her to many of the horrors portrayed in the movie. Her mistaken recall best illustrates:

Her mistaken recall best illustrates source amnesia.

Explanation:

Source amnesia can be defined as a memory disorder in which a person is able to recall a factual knowledge, but they distort contextual elements such as where, when, or how they obtained it, or simply cannot recall those elements. This type of amnesia is associated with the malfunctioning of explicit memory. Notice that Margo can remember the horrors portrayed in the movie, but she is unable to recall that she obtained that information from the movie, not from something that truly happened to her.

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)
