Which of the following is not true of Pluto?

Pluto is larger than any other Kuiper Belt objects

Why did the outer planets form differently than the inner planets?

Outer planets were past the frostline and accumulated ice

Why was the discovery of "blueberries" on Mars's surface so important?

It proved that there was once water on Mars

How and why does a comet change as it approaches the Sun

It heats up and the ice begins to melt and create a tail

What evidence do we have that Mars had much more liquid water at its surface in the past?

Both sedimentary rocks and dry channels and valleys

How did our solar system form?

After the Big Bang, gravity pulled dust and gases together

How do the inner planets compare to the outer planets?

The inner planets are small and solid

Why does Mercury have such extreme changes in temperature?

Mercury has little to no atmosphere

Why is Uranus tilted on its axis?

A large planet knocked it over on its side early on

How did Jupiter get its rings?

Volcanic ash from a nearby moon

Why is it hotter on Venus than on Mercury even though Mercury is closer to the Sun?

Venus's atmosphere contains greenhouse gases

How are comet tails formed?

Sublimation as the comet heats up as it approaches the Sun

A magnetic field
A large volcano
2
Which of the following is not true of Pluto?
Pluto is larger than any other Kuiper Belt objects
Pluto’s orbit is highly elliptical
It formed differently from the outer planets
Pluto does not have enough gravity to clear its orbital path
3
What are Saturn's rings made of?
Solid ring of ice
Methane
Gases
Rock and Dust
4
Between Mars and Jupiter is a region of the solar system called the
Oort Cloud
Milky Way
Asteroid Belt
Kuiper Belt
5
Why did the outer planets form differently than the inner planets?
Outer planets were past the frostline and accumulated ice
The inner planets formed first
Only rock and no gases were found close to the Sun
The outer planets formed first
6
Why are Uranus and Neptune blue?
Atmosphere contains methane
Light bending through water vapor
Only appears that way because of filters on cameras
It is covered by an ocean
7
Some regions of Mars have giant
Lakes
Forests
Volcanoes
Rivers
8
Beyond which planet is the Kuiper Belt found?
Pluto
Saturn
Neptune
Mars
9
Why was the discovery of "blueberries" on Mars's surface so important?
It proved that there was once water on Mars
It allowed scientists to learn about Mars's soil
It proved for successful cultivation of a blueberry crop
It provided evidence of a past civilization
10
Which of the following planets does not have any rings?
Uranus
Saturn
Jupiter
Mars
11
All the known dwarf planets except Ceres orbit in the
Oort Cloud
Kuiper Belt
Milky Way
Asteroid Belt
12
Which part of a comet is solid?
Nucleus
Dust Trail
Gas Trail
Coma
13
How and why does a comet change as it approaches the Sun
It gains more mass
It gets larger as it collects dust in space
It heats up and the ice begins to melt and create a tail
It loses its gravitational attraction
14
Space debris that is a roughly mix of rock and ice is called a(n)
Comet
Meteroroid
Meteor
Asteroid
15
Mar’s atmosphere is composed mostly of
Oxygen
Hydrogen
Carbon Dioxide
Nitrogen
16
What evidence do we have that Mars had much more liquid water at its surface in the past?
Martian meteorites formed from lava that was nearly 2% water
Both sedimentary rocks and dry channels and valleys
Large dry channels and valley networks on the surface
Sedimentary rocks have been found on the surface
17
The inner planets that experience a greenhouse effect are
Venus and Earth
Venus and Mars
Mercury and Mars
Mercury and Earth
18
Which of the following is NOT a criterion to be considered a planet?
Orbit the Sun
Large enough for gravity to form a spherical shape
Have at least one moon
Cleared its orbital path of any other object
19
How did our solar system form?
The Big Bang Theory
A rouge star found the planets
Before the Big Bang, solar systems were already established
After the Big Bang, gravity pulled dust and gases together
20
Which factor about an asteroid has the greatest affect on the size of the impact crater?
Size of the asteroid
Location in the Solar System
Time of impact
Composition of the asteroid
21
How do the inner planets compare to the outer planets?
The inner planets are small and solid
Inner planets are small and gaseous
The inner planets are large and gaseous
The inner planets are large and solid
22
Why does Mercury have such extreme changes in temperature?
Mercury is the closest planet to the Sun
Mercury has little to no atmosphere
Mercury has no liquid water
Mercury has a greenhouse effect
23
Planetesimals,collided,stuck together and combined to form all the other objects in the
Universe
Galaxy
Solar System
Zodiac
24
Most comets originate in the
Milky Way
Oort Cloud
Kuiper Belt
Asteroid Belt
25
All the inner planets have an atmosphere except
Venus
Earth
Mercury
Mars
26
The Sun is a(n)
Planetismal
Asteroid
Star
Planet
27
Why is Uranus tilted on its axis?
A large planet knocked it over on its side early on
That's just the way it is
Solar winds and flares tilted it over
Due to its magnetic field it is tilted
28
One day is the time it takes a planet to rotate on its
Axis
Equator
Poles
Moon
29
What characteristics do all the outer planets share?
They have many moons

A destroyed moon
Left over debris from early formation
Asteroid impact
31

a meteor
a meterorite
a meteoroid
an asteroid
32
What feature is shared by all the inner planets?
Liquid water
Ring system
Thick atmospheres
Rocky Surface
33
Why is it hotter on Venus than on Mercury even though Mercury is closer to the Sun?
Venus's atmosphere contains greenhouse gases
Venus is covered by volcanoes
Mercury is covered in ice
Venus is sometimes closer to the Sun
34
How are comet tails formed?
