Science Warm-up
• Write in your agenda:
Quiz on Earth’s Layers
Wed!!
• Work on your glossary
or your flipbook.
Crust
• Composition = oxygen,
silicon, & aluminum,
iron, magnesium,
calcium
• Thickness = 5 to 100 km
• State of matter = solid
• Less than 1% of Earth’s
mass.
• Temperatures range
from Air temp to 1,000
Degrees Celsius
• Oceanic crust is heavier
than continental crust.
Mantle
• Composition = mostly
magnesium, little
aluminum & silicon
• Thickness = 2,550 to
2,900 km
• State of Matter =
asthenosphere is
liquid/solid and
Lithosphere is solid.
• Contains most of the
Earth’s mass 67%
• Temperatures from
1,000 to 3,700 degrees
Celsius
• Scientists must study
volcanoes to
understand!
Outer Core
• Composition = Iron &
Nickel
• Thickness = 2,200 km
• State of Matter = liquid
Inner Core
• Composition = Iron &
Nickel
• Thickness = 1,230 km
• State of Matter = solid
• Makes 1/3 of the
Earth’s mass.
• Temperatures are 3,700
– 7,000 degrees Celsius.
• This part spins
(magnetic field).
