What does a star’s color indicate?
• Its temperature
• Blue – hottest
• Reds- cooler
Why do astronomers put telescopes
in space rather than on Earth?
• To avoid the interference of the atmosphere.
What are the two distinctions
between the inner and outer planets?
• Terrestrial or rocky
• Gas Giants
H-R diagram shows what
information about the stars?
• Surface temperature and the absolute
magnitude
• (remember absolute is compared at same
distance, apparent is how bright they appear
to be from earth)
What is the composition of the
atmosphere?
• 78% Nitrogen
• 21% Oxygen
• 1% trace gases (CO2, water vapor, etc.)
The type of precipitation that is
formed by freezing in mid air.
• Sleet
How would you describe a
cirroculumus cloud?
Cirro – high
Cumulus - puffy
An area where air masses meet and
cause weather events.
• Fronts
•
Named for who is moving:
cold front
warm front
stationary front
occluded front
Describe the job of an anemometer
and a barometer
• Anemometer – measures wind speed
• Barometer – wind pressure (in millibars)
Why is the Earth’s inner core solid
and the outer is fluid?
Although the inner core is hotter, there is
more pressure, keeping it solid.
The outer core is more fluid and causes the
earth to have a magnetic field.
What theories were combined to
create the plate tectonics theory?
Continental drift (Pangaea)
Seafloor Spreading (mid ocean ridge and
subduction)
Identify the motion each boundary
makes:
Convergent
divergent
transform
• Convergent – comes together (compression)
• Divergent – pulls apart (tension)
• Transform – slips past (strike –slip)
Are the plates of the Earth still
moving?
• Yes, at about a rate of 2 cm per year.
(that is how quickly average people’s
fingernails grow)
Which type of crust typically
subducts and why?
• Oceanic crust is less dense than continental
crust, so when they bump into each other,
oceanic subducts.
• Oceanic/oceanic – older denser stays up
• Continental/continental – form folds and
mountains
Describe the differences between
chemical and mechanical
weathering.
• Chemical is breaking down rock using
chemical reactions
• Mechanical breaking down the rock using
physical means
How are erosion and weathering
different?
Weathering just breaks down the rock
Erosion moves the pieces away and deposits
in another area.
Saltatation, abrasion, and deflation
are all types of what kind of erosion?
• Wind erosion
What are the three types of rock?
• Sedimentary, metamorphic and igneous
Name 2 types of mass movements of
soil or rock.
Land slides
Mud flows
Rock slides
Creep –(slow moving)
Can you identify the forces that
caused this erosion?
• Water
Name two of the 4 types of wetlands
• Marshes –dominated by soft stemmed
vegetation
• Swamps– woody plants
• Bogs -freshwater wetlands with spongy
peat deposits, evergreen trees and shrubs,
and a floor covered by moss
• Fens- grasses, reeds and wildflowers
•
The area where all the water
drains into a certain sight (big
bathtub)
Watershed
Which of the following could hit you
in the head here on Earth?
Meteor
Meteorite
Meteoid
• Meteorite – this is a meteoroid after it has
entered Earth’s atmosphere
AUDIO DAILY DOUBLE
Can you sing any words to this
song?
The sun is a mass of incandescent gas, a
gigantic nuclear furnace. Where hydrogen
was built into helium at temperatures of
millions of degrees…
Who is energy man and how does he
get here, dude?
• Energy “man” comes to earth on
electromagnetic WAVES
• “rad”iation
• Convection
• Conduction
