Which of these describes Earth's crust? Mark all that apply.
the layer of rock that forms Earth’s outer skin
the thickest layer of Earth
about 5 to 40 km thick
made of molten rock
Which of these describes Earth's mantle? Mark all that apply.
a layer of hot rock
the upper mantle and crust are called the lithosphere
the hardest layer is called the asthenosphere
the mantle is 10,000 km thick
Which of these describes Earth's core? Mark all that apply.
it contains no nickel or iron
the core makes up ⅓ of Earth’s mass, but 15% of Earth’s volume
consists of three parts: lower mantle, outer core and inner core
the inner core is a dense ball of solid metal
What are the three ways that energy is transferred in the atmosphere?
core, mantle & crust
temperature, pressure & humidity
radiation, conduction & convection
induction, conduction & radiation

True or False. All theories support the idea that it has taken hundreds of millions of years for continents to move to their present locations.
True
False
What sources give us information that land masses were once connected?
water, air & land
beaches, cliffs & valleys
landforms, fossils & climate
rift valleys, sea-floor spreading & trenches
Who proposed the theory of sea-floor spreading?
Alfred Wegener
Harry Hess
Isaac Newton
Mr. Meier
What are the three pieces of evidence that support the theory of sea-floor spreading?
molten material, magnetic stripes & drilling samples
rift valleys, trenches & mid-ocean ridges
conduction, convection & radiation
air, water & land
What is subduction?
A process that allows submarines to stay under water
A process that allows part of the ocean floor to sink back into the mantle
A process used to map the ocean floor
A process that allows sand to stay on the beaches
