1.Iron ore consists mainly of iron atoms and oxygen atoms joined to each other
v v v v v v v v v v v v v
to form several different possible forms of iron oxide. Which branch of physical
v v v v v v v v v v v v v
science MOST directly deals with developing ways to remove the oxygen from
v v v v v v v v v v v v
iron oxide, thus leaving iron metal?: Chemistry

2.Which field of physical science deals MOST directly with which atoms join
v v v v v v v v v v v
together to form molecules?: Chemistry

3.Iron ore consists mainly of iron atoms and oxygen atoms joined to each other
v v v v v v v v v v v v v
to form iron oxide. Which branch of physical science MOST directly deals with
v v v v v v v v v v v v v
determining the kinds of rock formations likely to contain iron ore?: Earth

4.Which field of physical science MOST directly explains how the motion of the
v v v v v v v v v v v v
continents over 100 million years led to mountains and volcanoes in some
v v v v v v v v v v v v
places above land and deep ocean trenches in other places beneath the ocean
v v v v v v v v v v v v v
surface?: Earth science

5.Satellites orbiting Earth scan the light reflected from below, and the data can
v v v v v v v v v v v v
then be analyzed to get information about the objects that reflected the light.
v v v v v v v v v v v v v
This technology is called "remote sensing." For example, they can even
v v v v v v v v v v v
distinguish between Astroturf in a football field and real grass on the ground
v v v v v v v v v v v v v
below, even though these look the same to the human eye.

Which field of science would MOST directly devise ways to detect and analyze
v v v v v v v v v v v v
reflected light obtained by remote sensing?: Physics

6.A scientist sets out to test his hypothesis that warmer sand temperatures
v v v v v v v v v v v
during the incubation of turtle eggs produce female hatchlings and cooler sand
v v v v v v v v v v v v
temperatures produce males. The independent variable is: the tempera- ture.

8.Which term BEST describes a research project in which scientists place
v v v v v v v v v v
microphones at the bottom of the seafloor to study the sounds orca whales

make?: A field study

9.The Hubble space telescope was launched into orbit to take far sharper
v v v v v v v v v v v
images than possible on Earth. It has since collected data that show some
v v v v v v v v v v v v v
distant stars to have planets. The scientific investigation involved is BEST
v v v v v v v v v v v
described as: an observational study

11.Many species of fish contain a swim bladder within their body that is filled with
v v v v v v v v v v v v v v
gas and helps the fish to control and maintain their depth below the water.
