6
A divergent boundary is where the plates are
moving apart
none of these

31
Why was Alfred Wegener's theory originally rejected by scientific peers?
His theory didn't make any sense.
He had no evidence.
They already knew the continents could not more.
He couldn't explain how the continents moved.
