Was continental drift accepted in Wegener's lifetime?
Yes
No
Yes, but only by his fiance.
No, but scientists told him to never give up.
Why did no one believe Wegener's theory?
He could not explain HOW the continents moved.
He was a meteorologist and not a geologist.
His evidence was not supporting the hypothesis.
He didn't use the right technology to gather data.
