The densities of the Jovian planets are

• not more than about 0.5 times the density of water.

• not more than about 1.5 times the density of water.

• from 3.9 to 5.5 times the density of water.

• more than 5.5 times the density of water.

According to scientists, the solar system formed from

• colliding planetesimals.

• rotating stars.

• colliding nebulae.

• a rotating disk of dust and gases.

Which of the following is one difference between the way terrestrial planets and Jovian planets formed?

• The terrestrial planets formed only from bits of ice.

• The Jovian planets formed only from bits of ice.

• The terrestrial planets formed only from metals and silicate minerals.

• The Jovian planets formed only from metals and silicateminerals.

How does the diameter of the terrestrial and Jovian planets compare?

• The diameters of the Jovian planets are much larger.

• The diameters of the terrestrial planets are much larger.

• All but one of the terrestrial planets have diameters about equal to the diameters of the Jovian planets.

• All but one of the Jovian planets have diameters about-equal to the diameters of the terrestrial planets.

The fact that Mercury has no atmosphere is evidence that it

• reflects almost all of the sunlight that strikes it.

• is composed almost entirely of gases.

• is much farther from the sun than it appears.

• reflects a small percentage of the sunlight that strikes it.

One reason that life as we know it is unlikely to exist on Venus is because

• the surface temperature is too high.

• the surface temperature is too low.

• the surface has too much ice covering it.

• there is no atmosphere.

When viewed from Earth, Mars appears to change colors. This most likely happens because

• gases in the dense Martian atmosphere are constantly changing.

• volcanic activity produces thick gas clouds.

• dust storms lasting for weeks cause the atmosphere to change color.

• active volcanoes on the Mars surface intermittently flood the surface with lava.

What is the mass of Jupiter?

• 2.5 times the mass of Earth

• twice the mass of all the terrestrial planets

• about half the mass of all the Jovian planets

•  2.5 times the mass of all the other planets and their moons
