Section 1 Test
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?
Chemistry
Which field of physical science deals MOST directly with which atoms join together to form molecules?
Chemistry
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?
Earth science
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?
Earth science
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?
Physics
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
the temperature.
The variable that a scientist changes in an experiment is called the
independent variable.
Which term BEST describes a research project in which scientists place microphones at the bottom of
the seafloor to study the sounds orca whales make?
A field study
, The Hubble space telescope was launched into orbit to take far sharper images than possible on Earth. It
has since collected data that show some distant stars to have planets. The scientific investigation
involved is BEST described as
an observational study
Which field relies the MOST on laboratory studies?
Chemistry
Many species of fish contain a swim bladder within their body that is filled with gas and helps the fish to
control and maintain their depth below the water. Which fields of science MOST directly explain the
operation and evolution of the swim bladder of fish?
Physics and life science
A class carries out an experiment in which they allow the weight of the block with mass m2 to pull block
m1 into motion, and then they measure the speed attained each time the hanging mass reaches the
ground. They repeat this for different masses m2. The independent variable is
the mass m2.
Which topic dealt with by physics would be the MOST DIRECTLY important in life science?
How drag forces influence the motion of bacteria as they swim through water
When the electric eel needs electricity, its complex system of nerves simultaneously activates thousands
of electricity-producing cells. As each cell receives the signal, it releases a tiny amount of the molecule
called AChE. The study of the properties and interactions of AChE would be in the realm of
chemistry.
Ocean tides are caused by the force of gravity mainly from the moon and secondarily from the sun as
Earth rotates on its axis. Which pair of physical sciences MOST directly deals with the tides and what
causes them?
Physics and Earth science
Geckos are known for being able to walk on very smooth surfaces, even upside down. Tiny ridges on the
gecko's feet allow it to stick to a smooth glass surface because of weak forces between the atoms in the
gecko's foot and the atoms in the glass.
Which pair of physical sciences would be MOST relevant in investigating how a gecko sticks to glass?
Physics and chemistry
Which physical science MOST directly deals with the fundamental nature of time, space, energy, forces,
and motion of matter?
Physics
The statement, "The total energy in a closed system stays constant,” is based on many years of
experimental observations. The statement is an example of a
