Which sentence in this candidate’s platform is a fact? Sarah Jones
Hello, everyone! My name is Sarah Jones and I’m in eighth grade. I’m running for student body president because I want to improve the experience of students in this school. Although I’ve never been on student council, I promise you that I’ll work very hard to understand your needs.

It is my number-one priority to give you the best experience possible. Take school clubs, for example. Our school currently has only three after-school clubs: a book club, a gaming club, and a dance club. As president, I want to introduce more choices for after-school clubs. I think we should have engineering, creative writing, and cultural clubs. These activities will help us explore different interests, build new skills, and make new friends. I’ll also make sure that the library is open during all lunch periods. That will give us some extra time to study.

Your thoughts and ideas are important to me, and I encourage you all to vote in our election. Thank you for your support!

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)
