What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

Why did no one believe Wegener's thoery?

• He could not explain HOW the continents moved
• He didn't have evidence
• His data was wrong
• He didn't use the right technology to gather data
