Karen has lived in the same neighborhood since she was born. Her parents informed her that they would be moving across the country for her dad's new job. Even though she is excited about living in a bigger house, Karen is feeling stressed by the idea of making new friends and learning her way around a new school.. According to the information given, Karen is most likely experiencing stress related to .

A. frustration
B. conflict
C. change
D. pressure

C: Change

Explanation:

Her sudden change of residence causes her to worry whether she would be able to make new friends and familiarize herself with her new school. Since she has never faced this situation before, considering that she has lived in the same neighborhood all her life, she is fearful of what she might face in the new neighborhood, since she does not know what to expect.

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)
