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?
