The name of the author is the first to go followed obediently by the title, the plot, the heartbreaking conclusion, the entire novel which suddenly becomes one you have never read, never even heard of, as if, one by one, the memories you used to harbor decided to retire to the southern hemisphere of the brain, to a little fishing village where there are no phones. Long ago you kissed the names of the nine Muses goodbye and watched the quadratic equation pack its bag, and even now as you memorize the order of the planets, something else is slipping away, a state flower perhaps, the address of an uncle, the capital of Paraguay. Whatever it is you are struggling to remember, it is not poised on the tip of your tongue, not even lurking in some obscure corner of your spleen. It has floated away down a dark mythological river whose name begins with an L as far as you can recall, well on your own way to oblivion where you will join those who have even forgotten how to swim and how to ride a bicycle. No wonder you rise in the middle of the night to look up the date of a famous battle in a book on war. No wonder the moon in the window seems to have drifted out of a love poem that you used to know by heart. in the poem, what is compared to the idea of losing one's memories?
A. writing
B. fishing
C. retiring
D. kissing

they encountered severe weather for which they were poorly prepared.

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)
