Topics:
Earth’s Systems
- Geosphere
- Hydrosphere
- Biosphere
- Cryosphere
- Atmosphere
Earth’s Interior/Layers
- Place the layers of the Earth in
order from the surface to the
center.
- What happens to the
temperature as we travel from
the surface to the center of the
Earth? The pressure? The
density of the rock?
- What is the lithosphere?
Asthenosphere?
- What is the composition of
each layer?
- What is the state of matter of
each layer (solid/rigid, liquid,
gas, plastic?)?
- What are the properties of the
two types of crust
(oceanic/continental)?
Plate Tectonics Test Study Guide & Review
Continental Drift Hypothesis
- Who came up with the
hypothesis that continents were
once connected?
- What evidence did he use to
back up his hypothesis (use
foldable)?
- How was the puzzle-like fit,
rock, climate, and fossil
evidence used to support his
hypothesis?
- Did scientists believe Wegener?
Why or why not?
o Scientists did not know
HOW the continents
drifted.
Seafloor Spreading
- What happens at a mid-ocean
ridge?
- Where does new crust form and
where is does older crust go?
- How do magnetic alignments of
iron minerals in oceanic rock
help us determine how the
seafloor is spreading?
- How does temperature of ocean
rocks help us determine how
the seafloor is spreading?
- How does rock dating help us
determine how the seafloor is
spreading?
Forces Involved in Plate Tectonics
- What is a convection current?
- Why do convection currents
occur in the mantle? (heated
unequally)
- What property of the
asthenosphere allows tectonic
plates to move?
- Describe the four forces that
drive plate tectonics.
o Convection in the mantle
o Ridge push
o Slab pull
o Basal drag
- What is a subduction zone?
- What happens when oceanic
crust collides with continental
crust?
Be able to label parts of the seafloor
spreading diagram. Be able to
explain the forces that drive plate
tectonics using this diagram.
