Section 1 Test Questions and Answers
1. Iron ore consists mainly of iron atoms and oxygen atoms joined to each
other to form several different possible forms of iron oxide. Which branch
of physical science MOST directly deals with developing ways to remove
the oxygen from iron oxide, thus leaving iron metal?
Answer Chemistry
2. Which field of physical science deals MOST directly with which
atoms join together to form molecules?
Answer Chemistry
3. Iron ore consists mainly of iron atoms and oxygen atoms joined to each
other to form iron oxide. Which branch of physical science MOST directly
deals with determining the kinds of rock formations likely to contain iron
ore?
Answer Earth science
4. Which field of physical science MOST directly explains how the motion
of the continents over 100 million years led to mountains and volcanoes
in some places above land and deep ocean trenches in other places
beneath the ocean surface?

, 5. Satellites orbiting Earth scan the light reflected from below, and the
data can then be analyzed to get information about the objects that
reflected the light. This technology is called "remote sensing." For
example, they can even distinguish between Astroturf in a football field
and real grass on the ground below, even though these look the same
to the human eye.
Which field of science would MOST directly devise ways to detect and
analyze reflected light obtained by remote sensing?
Answer Physics
6. A scientist sets out to test his hypothesis that warmer sand
temperatures during the incubation of turtle eggs produce female
hatchlings and cooler sand temperatures produce males. The independent
variable is
Answer the temperature.
7. The variable that a scientist changes in an experiment is called the
Answer independent
variable.
8. Which term BEST describes a research project in which scientists place
micro-phones at the bottom of the seafloor to study the sounds orca whales
make?
