axes
All eight (8) planets rotate on their ____________________.
gas giants
Another name given to the outer planets.
temperatures
Because of their distances from the sun, the outer planets have lower ____________________.
dwarf planets, moons, asteroids, and comets
Besides the planets and the sun and other stars, what are the objects are in our solar system? (Hint: there are four of them :)
axis
Earth turns around an imaginary line called a(n) ____________________.
one (1) day
How long does it take for Earth to make one full movement in space?
Mercury
It is the closest planet to the sun.
Neptune
It is the coldest and windiest planet in the solar system.
Jupiter
It is the largest planet in the solar system.
Mars
It looks red because of the iron oxide in its soil.
Saturn
Its rings are the largest and easiest to see.
Uranus
Its tilt is so great that it seems to revolve on its side.
Earth
Liquid water covers most of its surface.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
List the planets in order of their distance from the sun.
rings
Only the outer planets have these around them.
moons
Outer planets have many of these orbiting them.
inner planets
Probes have landed on these planets because their surfaces are hard.
new moon, first quarter moon, full moon, third quarter moon
Put these phases of the moon in the correct order: full moon, new moon, third quarter moon, first quarter moon
moons
Some of the inner planets have one or two of these. Others have none.
Mars
The fourth planet from the sun is ____________________.
orbit
The path that one object takes around another object in space is its ____________________.
planets
These are relatively large objects that have clear orbits around the sun.
Venus
Thick clouds of carbon dioxide make it the hottest planet in the solar system.
smaller
This inner planets have diameters that are ____________________ than those planets in the other group.
Because of Earth's revolution
This is the reason that we can not see some constellations from every location on Earth year-round.
The Earth's rotation
What causes it to be daytime in the U.S. when it is nighttime in China?
third quarter moon
What moon phase is pictured here?
Summer
What season is it in the United States when the Earth's North Pole tilts toward the sun?
relatively large cores
Which characteristic do all the inner planets in our solar system have? rings, many moons, lower densities, or relatively large cores
a turning top
Which of the following demonstrates how a rotating object moves? a falling rock, a turning top, a bouncing ball, a sliding hockey puck
Neptune; it is an outer planets. The rest are inner planets.
Which planet does not belong in this group? Why? Venus - Mercury - Mars - Neptune
The moon's revolution and rotation are about the same length.
Why does the same side of the moon always face the Earth?
Because its orbit crosses the orbit of another body.
Why is Pluto now classified as a dwarf planet?
