Standard
1b. Students know the evidence from Earth and
moon rocks indicates that the solar system was
formed from a large nebular cloud of dust and gas
about 4.6 billion years ago.
Objective 1
List and describe the 4
surface features of the moon.
Summarize the 3 stages by
which the moon formed.
Compare and Contrast the
moons of other planets.
Describe asteroids and
comets.
Compare meteoroids,
meteorites, and meteors

Assessment
Create a flashcard for
the following key
terms…they begin on
page 719.
•
Comet
• Satellite
•
Oort
cloud
• Moon
•
Meteoroid
• Galilean moon
•
Meteor
• Asteroid
•Any large body that
orbits a planet is a
SATELLITE. If it is a
natural satellite, it is a
MOON.
• Lighter areas are HIGHLANDS (mountains/volcanoes)
• Darker areas are MARIA (lava fields)
• The surface of the moon is covered in bowl-shaped
depressions called CRATERS
– Most of the moon’s craters formed from ASTEROIDS
colliding with the moon for 4 billion years
– The moon is covered in craters because it has no
atmosphere to protect it
• The moon is covered in dust and rock from space debris
called REGOLITH
• Lunar rocks are very similar to Earth’s rocks. They are
Igneous.
Giant
Impact
Hypothesis
• Mars-sized object collided with Earth 4
billion years ago. Chunks ejected from
earth and orbited the Earth, clumping
together to form the moon.
Lunar
Interior
• The moon was originally covered in
an ocean of molten rock. Over
time it cooled and denser material
sank to the center giving it layers.
Meteorite
Bombardment
• Asteroids and debris
left over from the
formation of the
solar system
continually struck
the moon forming
craters.
• Finish the bubble map…
Earth’s
Moon
• Mars, Jupiter, Saturn, Uranus, Neptune,
Pluto all have moons
• The 4 largest moons of Jupiter are known
as the GALILEAN MOONS
–3 are bigger than the Earth’s moon
–Io, Europa, Ganymede, Callisto
–Ganymede is larger than Mercury
• Tape the fill-in sheet into your notebook
• Answer the questions as we watch the
video
• Working in groups, use the
books and laptops to finish
the Scavenger Hunt
• 1 paper per group
Fragments of rock
that orbit the sun
Looks like a star
with a tail
Small bits of rock
More than 50,000
Made of ice, rock,
and cosmic dust
When a meteoroid
enters the atmosphere it
burns up, creating a
bright light or ‘shooting
star’ or METEOR
Ceres = largest
Asteroid Belt= Main
area of most
asteroid orbits
between the inner
and outer planets.
Orbit the sun
Tails form when
sunlight melts the
ice into gas
Less than 1mm
Meteorite= if a
meteoroid does not burn
up entirely and lands it is
called a METEORITE
• Dinosaur extinction caused by an
asteroid
• Can cause huge craters
• Most comets originate here
• A spherical cloud of dust
and ice beyond Pluto
• Surrounds our solar system
1. Create a Poster of one of the following:
a) Earth’s Moon
b) Other Moons (choose 1)
c) Asteroids
d) Comets
e) Meteoroids
2. Include a drawing, definition, and interesting
facts (at least 5)
3. Present to Class
