Even with the multiple pieces of evidence, why was Wegener's continental drift idea still rejected by scientists?

• He didn't have a mechanism for what caused the continents to move away from one another.

• He couldn't clearly communicate his evidence ideas when speaking.

• Glacial striations were found on multiple continents so it was inaccurate evidence.

• There wasn't enough fossil evidence to support his idea - island hopping sounded more accurate.

How did the scientific community respond to Wegener's theory?

• They agreed with him

• They rejected it

What does the theory of continental drift state?

• The Earth is broken into lithospheric plates that move due to convection currents

• Continents are stationary and do not move

• The continents were once joined in a super-continent and have moved over time

• None of the above
