1. A probe traveling through outer space is moving
at a constant velocity. Which statement applies to the motion of this probe?
A. An unbalanced force is acting on the probe, causing it to accelerate.
B. The probe will undergo constant acceleration until a force acts on it.
C. The probe will continue on its current path until an unbalanced force acts on it.
D. The force that makes the probe move through space is equal to its mass divided by its velocity.

2. Research indicates that galaxies are moving away from Earth. Which method allows astronomers to determine
this movement?
A. Observing these galaxies with a telescope
B. Listening to the radio waves that these galaxies emit
C. Detecting the kind of particles that these galaxies emit
D. Measuring the wavelengths of radiation from these galaxies
Justification--__________________________________________________________________________
3. Astronomers often try to find the hottest stars in our galaxy. Which wavelength of radiation do astronomers use
to detect these hottest stars?
A. Infrared
B. Ultraviolet
C. Visible

1. How can the wavelengths of light from a distant galaxy be used to determine the distance between Earth and
the galaxy?
A. The color of light from a galaxy indicates the age of the galaxy, and the most distant galaxies are the oldest.
B. The light from distant galaxies shows a shift to longer wavelengths, and the shift increases as the distance
increases.
C. The light from a distant galaxy is scattered by dust in the space between Earth and the galaxy, and the amount
of scattering indicates distance.
D. The most distant galaxies emit the most light in the x-ray part of the spectrum, and the distance can be
determined based on the strength of this light.

1. The following diagram shows the relative positions of Earth and the sun
during June’s summer solstice.
On this day, how does the angle of Earth’s axis affect the number of daylight
hours?
A. All places on Earth experience the maximum number of daylight hours.
B. Only places near the poles experience the maximum number of daylight
hours.
C. Only places in the Northern Hemisphere experience the fewest number of
daylight hours.
D. All places in the Northern Hemisphere experience the maximum number of daylight hours.
Justification--__________________________________________________________________________
2. The following diagrams show the axis of Earth at its present 23° angle
and at a perpendicular axis of 0°.
How would seasons be affected if Earth’s axis were at a 0° angle?
A. Earth would have no seasons.
B. Seasonal variation would decrease at the poles.
C. Seasonal variation would increase at the equator.
D. Earth would have two seasons instead of four seasons.

1. Early in the afternoon, a weather station outside the school shows that the barometric pressure and temperature
are both dropping rapidly. What type of weather do these readings indicate?
A. Several days of clear, sunny weather
B. Cool, cloudy weather with little chance of rain
C. Thunderstorms later in the afternoon or evening
D. Clearing weather today with rain likely tomorrow
Justification--__________________________________________________________________________
2. Which of these is a cause-and-effect relationship of hurricane factors?
A. An increase in air pressure causes the hurricane’s wind speed to decrease.
B. A decrease in wind speed causes a decrease in the hurricane’s longitude.
C. An increase in air pressure causes an increase in the hurricane’s wind speed.
D. A decrease in the hurricane’s latitude causes the hurricane’s longitude to decrease.
