2
Where is the Kuiper belt located?
beyond C
between A and B
between the sun and A
between B and C
3
Earth's moon formed from
the fission theory.
a large asteroid that was captured by Earth's gravity.
the sun's core ejecting it from it's rapid rotation.
a collision between Earth and a Mars-sized object.
4
Why does the asteroid belt contain possibly millions of asteroids?
the asteroids collide repeatedly -forming smaller asteroids
the solar system began in the asteroid belt
the asteroid belt is the edge of the solar system
Jupiter's powerful gravity attracts more minor bodies
5
The solar system's habitable zone is the location where temperature ranges allow
multicellular lifeforms to evolve from singlecell life forms
hydrogen & oxygen to form water molecules
water to exist in liquid form
a planet's atmosphere to maintain a water balance
6
Where is the asteroid belt located?
between the sun and Mercury
beyond Neptune
between Mars and Jupiter
between Jupiter and Saturn
7
Which answer best explains why a comet has a tail?
solar winds carry the heated dust and gas
comets are categorized by nature of their tails
When it is close to the sun, it reflects the sun's light
its high velocity shakes loose a stream of gas and dust
8
Which best classifies the planets of our solar system based on their physical characteristics?
blue and red planets
dead and living planets
gas giants and terrestrial planets
fluid and solid planets
9
Why is a meteorite impact unlikely to trigger a mass extinction?
it is likely that a meteorite will trigger a mass extinction
meteorites cannot impact the Earth
meteorite impacts are extremely rare
meteorite impacts are common, but burn up in our atmosphere
10
Which of the following is generally considered to be a minor body in the solar system?
all answers
moon
dwarf planet
comet
11
The most widely accepted explanation for the origin of Earth's moon is called
the fission theory
the big bang theory
the giant impact hypothesis
the nebular hypothesis
12
In which group of stars is our solar system located?
a solar nebula
the Andromeda galaxy
the Milky Way galaxy
a planetary nebula
13
Why does a meteor glow?
It burns up as it enters Earth's atmosphere
It reflects sunlight as it orbits the sun
it melts as it orbits the sun, releasing a tail of H20 vapor
it reacts with oxygen in Earth's atmosphere & breaks apart
14
According to the most commonly accepted hypothesis, our solar system formed from a
solar nebula
crab nebula
galactic nebular
planetary nebula
15
According to the International Astronomical Union, why is Pluto no longer considered a planet
It does not follow an elliptical orbit around the Sun.
It's not massive enough to clear smaller bodies around it
It's too massive to assume a nearly rounded shape.
Its mean distance from the Sun is greater than 35 AUs.
16
A meteoroid that reaches Earth's surface is called
a meteorite
a meteor
a stony meteoroid
an iron meteroid
17
Which statement does NOT correctly identify a planet in the solar system?
Mercury is an inner terrestrial planet.
Neptune is an outer gas giant.
Jupiter is an outer gas giant.
Mars is an outer terrestrial planet.
18
A scientist studying minor bodies in the solar system would likely learn
the composition of early forms of life
the processes that formed the galaxy
the composition of the early solar system
the processes that formed the planets

between C and D
between the sun and A
between A and B
beyond D
22
The most commonly accepted hypothesis describing the origin of our solar system is called the
Doppler hypothesis
nebular hypothesis
steady state hypothesis
stellar hypothesis
23
Planets form when the matter in an accretionary disc begins to coalesce. The accretionary disc
surrounds a supernova
surrounds a black hole
surrounds another planet
surrounds a star
24
What is a comet?
a small body of ice, rock, and dust that orbits the sun
the trail of light seen from Earth as a meteoroid burns up
any minor body that orbits the sun past the orbit ofNeptune
an irregular shaped piece of debris
25
