What is occuring in this picture?
Water rises less dense, as it gets towards the top it becomes denser.
Magma rises denser, as it gets towards the top it becomes less dense.
Magma rises less dense, as it gets towards the top it becomes denser.

10
What type of boundary is this?
Divergent
Transform

11
Why was the theory of continental drift rejected by Scientist?
There was a competing theory at the time which was more believable
The scientists didn't know of a force strong enough to move the continents
The scientist presenting the data was unreliable.
There was no data showing the continents ever moved.
