What is the mass of Jupiter

2.5x the mass of all other planets and their moons

difference b/n how the terrestrial and Jovian planets formed

terrestrial formed only from metals and silicates

What is true of asteroids

caused the impact craters on the moon

mercury has no atmosphere so

it reflects a small portion of sunlight that hits it

What is NOT a source of meteoroids

rocky chunks from outside our solar system

Which of the planets have rings

Saturn, Jupiter, Uranus, Neptune

Kuiper Belt is a region past Neptune containing

comets with short orbit periods

Mars appears to change colors because

dust storms lasting weeks cause atmosphere to change color

the densities of the Jovian Planets are

less than 1.5x the density of water

Questions 20

Answers

1
What is the mass of Jupiter
2.5x Earth's
2x that of the terrestrial planets
1/2 the mass of all the Jovian planets
2.5x the mass of all other planets and their moons
2
difference b/n how the terrestrial and Jovian planets formed
terrestrial formed from bits of ice only
Jovian formed from only metals and silicates
Jovian formed from bits of ice only
terrestrial formed only from metals and silicates
3
What is true of asteroids
rarely pass close to Earth
almost never collide with planetary bodies
most are no larger than pebbles
caused the impact craters on the moon
4
mercury has no atmosphere so
it is much farther from the sun than it appears
it reflects a small portion of sunlight that hits it
it is composed almost entirely of gases
it reflects almost all light that hits it
5
What is true of comets
held together by frozen gases
orbits do not go past Jovian planets
all comets have long tails
Oort Cloud of comets if between Neptune and Pluto
6
What is NOT a source of meteoroids
material from the asteroid belt
solid remains of comets
leftover interplanetary debris
rocky chunks from outside our solar system
7
diameters of the terrestrial and Jovian compare
terrestrial planets have diameters equal to the Jovian
terrestrial are much larger
Jovian planets are much larger
all but one Jovian have diameters equal to the terrestrial
8
Size of Halley's comet nucleus
100 km
16 km x 8 km
1 m
1 km
9
Which planet has lowest surface temp and an atmosphere made mostly of nitrogen
Saturn
Neptune
Uranus
Juptier
10
What does the asteroid belt lie in between
Mars and Jupiter
Mars and Earth
Jupiter and Saturn
Jupiter and Neptune
11
Which of the planets have rings
Saturn, Jupiter, and Neptune
Saturn and Neptune
Saturn and Jupiter
Saturn, Jupiter, Uranus, Neptune
12
Kuiper Belt is a region past Neptune containing
comets with large nuclei
dense collection of meteoroids
meteors smaller than 1 km across
comets with short orbit periods
13
Life is unlikely to exit on venus because
there is no atmosphere
surface has too much ice covering it
surface temp is too cold
surface temp is too high
14
Mars appears to change colors because
volcanic activity produces thick clouds
gases in the atmosphere are changing
dust storms lasting weeks cause atmosphere to change color
active volcanoes flood the surface with lava
15
the age of our solar system was estimated using
meteroites
comets
meteors
asteroids
16
the densities of the Jovian Planets are
less than 1.5x the density of water
3.9 to 5.5x the density of water
more than 5.5x the density of water
less than .5x the density of water
17
the solar system formed from
colliding nebulae
colliding planetesimals
rotating disk of gas and dust
rotating stars
18

mercury
jupiter
mars
venus
19

Venus
Uranus
Earth
Saturn
20
