At the start of most presidential campaigns, have already decided on the candidate who will get their votes.

The correct answer is C) about two-thirds of voters.

At the start of most presidential campaigns, about two-thirds of voters have already decided on the candidate who will get their votes.

A considerable number of voters had already decided who they are going to vote at the beginning of presidential campaigns. These people have always voted for the same political party or other voters have sympathized with any particular candidate for its ideas or charisma. That is why is so important for the campaign team to address the proper messages to swing voters and undecided voters. They are the ones who can move the balance to one side. The other options of the question were A) all registered voters. B) about one-third of voters. D) swing voters.

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)
