What is a feature due to lunar
volcanoes?
$400
Erosion (by the Colorado
River)
The Grand Canyon is formed
by what kind of process?
$600
Two tectonic plates colliding
Mountain chains such as the
Himalayans are formed due
to what process?
$1000
trench
What feature is formed in the deep parts of the
ocean where dense oceanic plate subducts
beneath lighter continental plate
$800
Rift valleys, trenches, mountains, volcanic
chains, faults,mid-ocean ridges
What are three surface features
due to plate tectonics?
$200
Spring
The type of tide with the
largest tidal variation is?
$400
small
Would 1st quarter moon
phase have a large tidal
range or a small tidal
range?
$600
The moon lacks an atmosphere, wind and
water
The rate of erosion on the
moon is less than Earth
because?

Examples of Hot spots on Earth are
$1000
In the mid-ocean ridges where plate tectonics
constantly extrudes new lava
Explain where is the newest material in
the Earth’s crust found?
$200
Jupiter
Which planet’s mass is more
than the mass of all the other
planets put together?
$400
No, the denser planets lie closer to the sun
Is this statement trueplanetary density increases
with increasing distances to
the sun? Why or why not?
$600
Venus and the Gas Giants
Which planets’ rotations are
difficult to determine due to
their atmospheres
$800
The Jovian planets
Which planets have rings
around their equator?
$1000
Terrestrial, Jovian
_____________________ are
planets that are of denser materials
such as iron and silicates.
________________ are less dense
and made of gases like the sun.

Impact Theory
Which theory currently best explains the
moon’s origin?
$400
Accretion
The term for the growth of a
celestial object by accumulating
matter is called?
$600
Spins faster due to angular momentum
Once the solar nebula contracts
what does it do next?
$800
The terrestrial planets are of heavier
elements and smaller, the Jovians are
lighter, larger and have more moons and
faster rotational periods
What are three reasons the
planets are split into two
groups?
$1000
A nebula collapses, spins faster and flattens into a disk.
The center of the disk heats up forming protosun and proto
planets. Protoplanets collect material (accrete), their
gravity takes over and they become planetesimals. These
collide and become planets. Leftover debris became
asteroids and comets.
Describe the theory of the
origin of the solar system.

Where is the Kuiper belt
found

From a spacecraft sent to an asteroid
What has given us the most
detailed look of an asteroid?
$800
A Kuiper belt object, a dwarf planet and a
plutoid.
What is Pluto considered?
$1000
Both orbit near the ecliptic plane,Asteroids are closer
in between mars and Jupiter while KPO are past

Neptune
The jovian planets are?

Terrestrial Planets
The asteroids are most
like________________ ________________
in composition and density.
$600
The process of transfer heat from hotter to
cooler levels
What is convection?
$800
Most interplanetary debris was swept up
during the formation of the solar system
The fact that the rate of cratering has
died down over time shows that
$1000
High density of terrestrial vs. Jovian.
Why do Jovians have thick atmospheres?
Why are asteroids made of primitive materials.
Why are comets icy?
Any theory of solar system formation must address
what issues?
