10
What is occuring in this picture?
Magma rises denser, as it gets towards the top it becomes less dense.
Magma sinks due to being less dense, as it gets towards the top.
Magma rises less dense, as it gets towards the top it becomes denser.
Water rises less dense, as it gets towards the top it becomes denser.
11
What type of boundary is this?
Seafloor spreading
Convergent
Divergent
Transform
12
Why was the theory of continental drift rejected by Scientist?
The scientists didn't know of a force strong enough to move the continents
There was a competing theory at the time which was more believable
There was no data showing the continents ever moved.
The scientist presenting the data was unreliable.

What was the theory that continents can drift apart from one another and have done so in the past?
Tectonic plate
Continental drift
Pangaea
Lithosphere

Radiant
Radiation
Convection
Conduction
