Which problem-solving strategy or method is correctly matched with its definition? select one: a. means-ends analysis: dividing a problem into intermediate steps b. forming subgoals: focusing on a problem's goal rather than its starting point c. working backward: reducing the apparent difference between the current state of the problem and the goal d. insight: experiencing a sudden awareness of the relationships among a problem's components?

d. insight: experiencing a sudden awareness of the relationships among a problem's components.

Insight is defined as suddenly being able to identify a problem's components, and to understand the relationships among them (for example, relationships of cause and effect). The moment of realization is sometimes called an "epiphany" or a "eureka" moment.

answer; (cognitive   dissonance);

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)
