Base your answer on the diagram. It shows twelve constellations that are visible in the night sky. Different positions of Earth are represented by letters A through D. The arrows represent the direction of Earth's motion around the Sun.
The constellations observed when Earth is at position A are different from the constellations observed when Earth is at position C because
Earth moves in its orbit
Earth is tilted on its axis
the lengths of day and night are different
the stars move around Earth as shown by star trails
How would a three-hour time exposure photograph of stars in the northern sky appear if the Earth did not rotate?
Which statement best supports the idea that the Earth rotates on its axis?
The stars appear to follow circular paths across the sky.
The apparent size of the Sun changes throughout the year.
The length of the day and night varies throughout the year.
The seasons (spring, summer, fall, and winter) repeat in a cyclic manner.
Which kind of model of the solar system is represented by the diagram?
heliocentric model
geocentric model
sidereal model
lunar model
Which statement best describes a geocentric model of our solar system?
The Earth is located at the center of the
model.
All planets revolve around the Sun.
The Sun is located at the center of the model.
All planets except the Earth revolve around
the Sun.
Why does the Sun generally appear to rise in the east, move across the sky, and set in the west each day?
Earth revolves around the Sun.
The Sun rotates on its axis.
Earth rotates on its axis.
The Sun revolves around Earth.
The cartoon characters are watching the Sun set. Toward which general direction are the characters looking?
north
south
east
west
How long does Earth take to complete one orbit around the Sun?
1 day
1 month
1 year
1 decade
The day and the year, as units of time, are based upon motions of
the Earth
the Moon
the Sun
distant stars
Summer days in North America are likely to be hotter than winter days because in summer
Earth is closer to the Sun
the number of sunspots increases
Earth’s northern axis is tilted toward the Sun
the Sun gives off more energy
The motions of comets and asteroids in our solar system are predictable because they are
smaller than planets
nearly spherical in shape
in orbit around the Sun
controlled by Earth's gravity
For which planet is the length of the planet's day longer than the planet's year?
Mercury
Venus
Earth
Mars
Our Sun located at the center of our solar system is
a planet
a star
an asteroid
a galaxy
Three planets that are relatively large, gaseous, and of low density are
Mercury, Jupiter, and Saturn
Venus, Jupiter, and Neptune
Mars, Jupiter, and Uranus
Jupiter, Saturn, and Uranus
The actual orbits of the planets are
elliptical, with Earth at one of the foci
elliptical, with the Sun at one of the foci
circular, with Earth at the center
circular, with the Sun at the center
Which of the following scientists would be most interested in a meteor?
astronomer
biologist
computer engineer
nuclear physicist
Which planet has vast amounts of liquid water at its surface?
Venus
Mars
Jupiter
Earth
A belt of asteroids is located between which two planets?
Mars and Jupiter
Mars and Earth
Jupiter and Saturn
Saturn and Uranus
An astronaut on the Moon weighs about one-sixth of his weight on Earth. This is because
astronauts lose mass when they are on the Moon
the Moon has a weaker force of gravity than the Earth
there is no atmosphere on the Moon
the Moon is so far away from the Earth
At which location is the gravitational attraction between the Sun and the planet greatest?
A
B
C
D
Which celestial feature is largest in actual size?
The Moon
Jupiter
the Sun
the Milky Way
Stars have a shape closest to that of a
pizza pie
basketball
pentagon
snowflake
The Milky Way galaxy is best described as
a type of solar system
a constellation visible to everyone on Earth
a region in space between the orbits of Mars and Jupiter
a spiral-shaped formation composed of billions of stars
In which list are celestial features correctly shown in order of increasing size?
galaxy → solar system → universe → planet
solar system → galaxy → planet → universe
planet → solar system → galaxy → universe
universe → galaxy → solar system → planet
Billions of stars in the same region of the universe are called
solar systems
asteroid belts
constellations
galaxies
Which arrangement of symbols is most accurate?
A black hole is a celestial feature believed to have a mass millions of times the mass of our Sun and a diameter less than the diameter of Earth. An object of such high mass and small volume would have
a very low density
a very high density
an elliptical orbit with the Sun at one focal point
an elliptical orbit with Earth at one focal point
Which statement best describes galaxies?
They are similar in size to the solar system.
They contain only one star but hundreds of planets.
They may contain a few hundred stars in a space slightly larger than the solar system.
They may contain billions of stars in a space much larger than our solar system.
Which of the following would most likely be studied by an astronomer?
the nucleus of an atom
new forms of plastics
distant galaxies
sound waves
A planet was viewed from Earth for several hours. The diagrams represent the appearance of the planet at four different times.
The best inference that can be made based on the diagrams is that this planet is
tilted on its axis
changing seasons
revolving
rotating
