A Moving and A Shaking

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 ideas about continental drift?

• He could not successfully explain HOW the continents moved

• He didn't have evidence that supported his ideas that the continents had once been connected

• They were biased against his ideas because he was German and a meteorologist

• He didn't use the right technology to gather data

According to Wegener's hypothesis of continental drift,

• Earth's surface is made up of seven major landmasses

• the continents DO NOT move

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass, and these plates will continue to move.

According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea?

• Animals easily and frequently travel from Africa to South America.

• Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis).

• Land bridges once existed that connected the continents.

• South America and Africa were once connected together.

What are the three types of Evidence that supports Alfred Wegener's Theory? 

• Fossils, Fish, and Land
• Sedimentary, Magma, and Climate
• Fossils, Land forms, and Climate
• Climate, Land forms, and Metamorphic rock
