You should avoid all of the following topics except. . . Topics that are controversial. Topics on a single source. Topics that are trivial. Topics that are contemporary.

Topics that are contemporary.

Explanation:

Hi. From the context of your question, we can see that you are referring to topics used to write a text or start a survey. In this case, among the types of topics presented above, you should not avoid contemporary topics, because they represent current and relevant issues in today's society and can enrich your text or research.

On the other hand, controversial and trivial topics should be avoided because of their irrelevance and low value. In addition, single-source topics should also be avoided as they do not present diverse and rich information.

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)
