Jack reports being in a wonderful mood. He has been very active at work lately, even working far into the night, as he seems to need only a few hours of sleep at night. He is very talkative and quickly moves from one topic to another, describing a scheme he has for making a fortune in the stock market. These behaviors represent a change from Jack's normal behaviors and have caused severe functional impairment. Which of the following diagnoses would best fit Jack? a. Bipolar Disorder
b. Overanxious Disorder

d. Cyclothymia.

answer; /// i believe the correct answer is (b) disposition

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)

the answer there would be genocide.
