While you are driving home, the car in front of you starts driving dangerously, so you concentrate on watching it. When you arrive home, you realize that you cannot remember anything from your drive home other than that car. Which of the following statements best illustrates the reason your memory is created this way?

A. that is very complex.
B. that exceeds the capacity of sensory storage.
C. that has two or more visual features.
D. to which we do not pay attention.

D. to which we do not pay attention

Explanation: The reason why one may be unable to remember anything other than the car cold most likely be due to lack of concentration or attention. Getting hold or grasping information requires attentiveness. Having a divided attention while learning will probably lead to missing some details or information being passed. Also, maintaining full concentration on a certain event will most likely mean that other events happening concurrently will be missed. Due to the impending danger as a result of the reckless driving of the vehicle ahead, one is fully concentrated on evading accident and landing safely. Therefore there is very high tendency of missing all other events happening at the same moment.

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)

south, because if you took a map you would see texas is directly in the middle of east and west, but it is also downwards towards mexico, therefore it is south
