WGU C165 INTEGRATED PHYSICAL SCIENCE
EXAM QUESTIONS AND ANSWERS LATEST 20
(SPRING)
• A mathematical model is used to predict the trajectory
of a bullet firedfrom a gun. Which discipline of physical
science is used to develop thismodel✔✔✔ Physics
• An environmental scientist monitors pollutants in a lake.
Which two disci- plines of physical science does this
scientist use? Choose 2 answers: Chem-istry
Earth Science
• Which study involves both Earth science and
physics✔✔✔ Calculating howmuch energy is associated with
a hurricane
• Which question could be answered with a controlled
experiment✔✔✔ Doesice melt faster in an empty glass or in a
glass full of water?
,• Which topic would be appropriate for a controlled
experiment✔✔✔ Determin-ing how fast different chemical
pollutants dissolve in water
• Sir Isaac Newton discovered that the force of gravity
between two masses increases if the masses increase, and
decreases if the distance between the masses increases. No
experiments have ever contradicted this relationship. Which
type of scientific statement is this✔✔✔ Law
• The well-accepted scientific explanation for many
characteristics of Earth's crust states that the crust is
broken into several large plates. Theseplates move slowly
over the mantle below because of convection and other
processes. Earthquakes and volcanoes are most common
at places where the plates interact. Evidence from physics,
chemistry, and geology supportsthis explanation. Which
type of scientific idea is this explanation an exampleof✔✔✔
Theory
,• Which question requires a controlled experiment to
answer✔✔✔ Which typeof rock contains the most calcium?
• A student proposes that sugar will dissolve faster in
rubbing alcohol thanin water. The student reasons that
sugar and rubbing alcohol both contain carbon so they will
mix more easily. Which type of scientific idea is the
student's proposal an example of✔✔✔ Hypothesis
• Why was the shrinking Earth idea replaced by the theory
of plate tecton- ics✔✔✔ Plate tectonics explained observations
about Earth that the shrinking Earthidea could not explain.
, • Astronomers have long accepted that plate tectonics
exists nowherein our solar system except on Earth. In
2011, a scientist analyzed 100
NASA-space-mission photographs of Valles Marineris on
Mars, the longest
known series of canyons in the solar system. The scientist
found that VallesMarineris showed features found only in
locations on Earth where major tectonic plates divide. What
would be the appropriate response of scientiststo this
information✔✔✔ Carry out further research to gain more
understanding of possible plate tectonics on Mars
• According to the theory of plate tectonics, volcanoes are
especially likelyto form along plate boundaries because of
rising magma. New satellite datamapping the ocean floor
reveals thousands of seamounts, which are small
volcanoes. Some of the seamounts are in lines that could
correspond to pastor present plate boundaries, but many are
not aligned in this way. How shouldscientists appropriately
respond to the idea that some new mechanism of forming
the volcanoes is involved✔✔✔ Carry out more research to
understand better how the seamounts form
