There are continental and oceanic plates.
True
False
6
Why do intrusive igneous rocks have bigger crystals?
Cooling time has nothing to do with it.
They cool at the same rate.
They cool slower.
They cool faster.
7
Why did other scientists not believe Wegener about continental drift?
He couldn't prove how the plates moved.
They were trying to steal his ideas.
He often said crazy things.
He didn't know about the fossil evidence.

magma
crystals
lava
layers
13
What is shown in this picture?

14
Why do you not find fossils in igneous or metamorphic rock?
Animals don't die by those rocks.
They are not hot enough.
The fossils don't like those rocks.

all of the above
monitoring seismic activity
issuing warnings to the public when necessary
building safer bridges, buildings, and subway tunnels
