WGU C165 STUDY GUIDE EXAM QUESTIONS AND ANSWERS
A mathematical model is used to predict the
trajectory of a bullet fired from a gun. Which
discipline of physical science is used to develop this
model? - correct answer Physics
An environmental scientist monitors pollutants in a
lake. Which two disciplines of physical science does
this scientist use? - correct answer Chemistry and Earth
science
Which study involves both Earth science and
physics? - correct answer Calculating how much energy
is associated with a hurricane
,WGU C165
Which question could be answered with a
controlled experiment? - correct answer Does ice melt
faster in an empty glass or in a glass full of water?
Which topic would be appropriate for a controlled
experiment? - correct answer Determining how fast
different chemical pollutants dissolve in water
Which question requires a controlled experiment to
answer? - correct answer Which type of rock contains
the most calcium?
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? - correct answer Law
, WGU C165
The well-accepted scientific explanation for many
characteristics of Earth's crust states that the crust
is broken into several large plates. These plates
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 supports this explanation. Which type
of scientific idea is this explanation an example of? -
correct answer Theory
A student proposes that sugar will dissolve faster in
rubbing alcohol than in 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? - correct
answer Hypothesis
Law - correct answer A body of enforceable rules
governing relationships among individuals and
between individuals and their society.
