Transcript Think-Pair-Share Questions

An Assessment: Think Pair Share
• Best procedures: read quietly to yourself
(so you don’t give any subconscious clues)
• As the instructor, we read it too, for timing,
then ask if anyone needs more time
• If not, it’s time to vote simultaneously—use
your fingers, right in front of your chest so
others don’t see
The North American continent is
1. a part of a larger tectonic plate that floats on the
asthenosphere
2. a part of a larger tectonic plate that floats on top of
the oceanic crust
3. a tectonic plate sinking beneath the Pacific plate
4. a tectonic plate that floats next to the Pacific plate
5. composed of at least two tectonic plates

Which of these features
should be seen at a
divergent boundary in the
ocean?
This is a topographic map of the

eruptions.

Only the Philippine Sea is moving
relative to the islands; it’s moving right.
Only the South China and Celebes Seas
are moving; they’re moving right.
The South China and Celebes Sea are
moving left; the Philippine Sea is moving
right.
The South China and Celebes Sea are
moving right; the Philippine Sea is
moving left.
All three seas are moving left.

All of them, because they are changes in elevation due to
interactions between the plates
B and E, because they are drop-offs from the continental shelves
B because it is a trench, and C because it is a ridge
C because it is a trench, and E because it is a mountain range
C because it is a mountain range, and A because it is a continental
shelf
Broad scientific interest and increasing testing
of the theory of plate tectonics waiting until the
1950’s and 1960’s, because
A.
B.
C.
D.
Discussions regarding continental drift or plate tectonics were
very limited –most scientists hadn’t heard about it.
Scientists were missing key data about the seafloor.
There was limited interest in volcanic eruptions and
earthquakes before then.
Ideas about mantle convection currents and seafloor
spreading began to get more attention.
