Inner Planets
Terrestrial
Rocky Crust and Metallic Core
Smaller in size
Warmer
More dense
Mercury
Venus
Rotate slower
Revolve faster
Less moons
No rings
Earth
Mars
Closet planet to the sun
2nd planet from the sun
3rd planet from the sun
4th planet from the sun
SMALLEST
Rotates backward and slow
243 days and revolves 225
days (1 day is longer than a
year!)
Atmosphere 78% Nitrogen
and 20% Oxygen
½ size of Earth
88 days to orbit the sun
Covered with craters
like the moon
24 hr day rotation
Can only be seen at
dawn and dusk
Similar in to Earth in SIZE
and DENSITY
400 C during day
HOTTEST planet 460 C due
to CO2 atmosphere that traps
heat = Greenhouse Effect
-200 at night
NO Atmosphere
365 days to orbit the sun
Core mostly iron
70% of the surface is water
Plate tectonics recycles the
Earth’s crust
Crushing atmosphere
90 times Earth’s atmosphere
Rains SULFURIC ACID
J. Hoffmann – Notes/J. Haugh – Visual Organizer/ Google Images/ X:Drive G.Org. Earth Science 2012
Thin CO2 Atmosphere
25 C - 125 C
Water in the form of ice
Once had river valleys
Has dust storms
Has extinct volcano called
Olympus Mons
