1. Meteoroid
What
are the Meteor
differences?

2. Meteoroid is a broken
up rock and dust from
either a comet, asteroid, the
Moon or from Mars.
When a meteoroid enters
Earth’s atmosphere, the air
in front of the meteoroid
heats up, causing materials
to burn up.

3. Meteor is a fragment
of the meteoroid that
burns up as it enters the
Earth’s atmosphere.

4. Meteorite is a
fragment from the
meteoroid survives
and makes it to the
ground

5. A meteor shower is a celestial
event in which a number of meteors
are observed to radiate, or
originate, from one point in the
night sky. These meteors are caused
by streams of cosmic debris called
meteoroids entering Earth's
atmosphere at extremely high
speeds on parallel trajectories.

6. How can you differentiate a
meteor from a comet
when viewed from Earth?
What differentiates
the two when we see
them in the sky is that
a comet moves
slowly and appears
in the sky for a longer
time.
A meteor moves
swiftly and seems to
fall on the ground. It
“shoots” from a point in
the sky, making people
think that it is a
shooting or falling star.

as small like
these but can be
as huge like

known as Tomanowos by the
Clackamas Chinook Native

is the largest known
intact meteorite

11. Types of Meteorites
Stony Meteorite Stony-iron Meteorite Iron Meteorite
The most common type of
meteorite; generally
composed of 75-90% silicon
based materials; n25%
nickel-iron alloy and trace
amounts of iron sulfide
Contain approximately
equal amounts of silicon
based materials and nickel-
iron alloy
Originated in the cores of a
large asteroid; composed
entirely of nickel-iron alloy,
which is also a primary
component of the Earth’s
core
