converge
means to MEET at a point.
True
False
3
What is the asthenosphere?
Earth's zone of air for breathing
Earth's mountain chains
Earth's crust and mantle
Earth's plastic-like layer
4
When tectonic plates meet 3 things can happen:
A volcanoe can form.
New crust is formed.
A mountain chain can form.
Crust is destroyed & the tectonic plate slides under the plate it meets.
5
The rock iron mineral pattern discovered by scientists shows that ____________.

False
True
8
What are the tectonic plates made of?
Computer parts
Crust and upper mantle
Sedimentary rocks
Ocean crust
9
What is continental drift?
continents are NOT moving
continents are drifting slowly
continenents are moving quickly
continents are connecting to each other
10
What can happen if two plates collide?
a line of mountains can form
a line of volcanoes can form
there will be an explosion
there will be an earthquake
11

Wegener couldn't get the world's scientist to accept continental drift because?
He couldn't prove how continents moved.
He couldn't prove that he was a scientist.-
He couldn't prove what rocks were eon continents moved.
He couldn't prove what animals were on the that continents moved.
14
What are
convection currents
that may cause tectonic plates to move?
the vertical movement of air
