plane.
Nearly all comets orbit the Sun in same direction and roughly the same
plane.
The Sun and most of the planets rotate in the same direction in which the
planets orbit the Sun.
All of the planets orbit the Sun in the same direction - counterclockwise as
viewed from above Earth's north pole.
Nearly all comets orbit the Sun in same direction and roughly the same plane.
Which of the following is not a major difference between the terrestrial and
jovian planets in our solar system?

Consider the following statement: "Rocky asteroids are found primarily in
the asteroid belt and Kuiper belt while icy comets are found primarily in
the Oort cloud." What's wrong with this statement?
The Kuiper belt contains icy comets, not rocky asteroids.
Comets are not really icy.
The statement is accurate as written.
,Asteroids are not really made of rock.
The Oort cloud has nothing to do with comets.
The Kuiper belt contains icy comets, not rocky asteroids.
Which of the following is not a real difference between asteroids and
comets?
It is thought that comets are far more numerous than asteroids.
Asteroids are made mostly of rock and comets are made mostly of ice.
Most asteroids are located much nearer to the Sun than most comets.
Asteroids orbit the Sun while comets just float randomly around in the
Oort cloud.
Asteroids orbit the Sun while comets just float randomly around in the Oort
cloud.
The following statements are all true. Which one counts as an "exception
to the rule" in being unusual for our solar system?
Saturn has no solid surface.
Venus does not have a moon.
Jupiter has a very small axis tilt.
The diameter of Earth's Moon is about 1/4 that of Earth.
The diameter of Earth's Moon is about 1/4 that of Earth.
Compared to the distance between Earth and Mars, the distance between
Jupiter and Saturn is ______.
much smaller
much larger
just slightly less
about the same
much larger
Einstein's famous equation, E=mc 2, explains the fact that __________.
, the Sun has a magnetic field strong enough influence the atmospheres of
the planets
the Sun is extremely massive
the Sun generates energy to shine by losing some 4 million tons of mass
each second
the Sun's surface temperature is about 6,000∘C
the Sun generates energy to shine by losing some 4 million tons of mass each
second
Venus has a higher average surface temperature than Mercury. Why?
Because its slow rotation gives it more time to heat up in sunlight.
Because its surface is covered with hot lava from numerous active
volcanoes.
Because its surface is heated by an extreme greenhouse effect.
Because it is closer to the Sun.
Because its surface is heated by an extreme greenhouse effect.
In what way is Venus most similar to Earth?
Both planets have warm days and cool nights.
Both planets are nearly the same size.
Both planets have similar surface geology.
Both planets have very similar atmospheres.
Both planets are nearly the same size.
Which of the following statements about the recently-discovered object Eris
is not true?
It is slightly larger than Pluto.
It is thought to be the first example of a new class of object.
It lies well beyond Pluto and Neptune.
It orbits the Sun in the same direction as the other planets.
It is thought to be the first example of a new class of object.
