Which type of scientific statement is this?
8. The well-accepted scientific explanation for many Theory
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. Evi-
dence from physics, chemistry, and geology supports
this explanation.
Which type of scientific idea is this explanation an
example of?
9. A student proposes that sugar will dissolve faster in Hypothesis
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
