sea-floor spreading and continental drift review

What was Wegener’s continental drift idea?

• The continents have moved slowly apart to their current locations.

• The continents have always been located at their current locations.

• The continents are moving slowly together from their current locations.

What evidence did Wegener use to support his theory?

• Continents and fossils fitting together/matching-up like puzzle pieces

• glacier scars and other climate evidence from temperature

• mountain ranges and rocks line up across continents

• all of the above

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

What evidence did Wegener have for his theory of continental drift?

• He had no good evidence.
• He knew that plant and animal fossils as well as rock layers matched up in South America and Africa.
• He explained how the continents moved

What geologic feature was evidence to support the theory that the continents used to be joined?

• Same rocks were found on different continents

• Glacial grooves were found on different continents

• Fossilized evidence of the same organism found on different continents

• Africa and South America look like puzzle pieces that fit together
