Question

1. What evidence did Alfred Wegener use to support his theory of continental drift? (Points: 1)
Wegener´s only evidence was that coastlines between continents fit together like puzzle pieces.

Coastlines fit together between different continents, and similar rocks and fossils are found on different continents.

Wegener had no evidence, which is why his theory was rejected.



2. In a convection cell, cold dense material rises, while hot, less dense material sinks. (Points: 1)
True

False



3. What is the name for the supercontinent that once formed from all the continents? (Points: 1)
Gondwanaland

Laurasia

Pangaea



4. Plates move on top of which layer of the earth? (Points: 1)
asthenosphere

crust

core



5. What is the source of earth’s internal heat? (Points: 1)
only radioactivity

only heat left from earth´s formation

both radioactivity and heat from

Answer 1

1: Both coastline shapes and similar rocks and fossils.

2: False.

3: Pangaea.

4: Asthenosphere.

5: Both radioactivity and residual heat.

Answer 2

1. Coastlines fit together between different continents, and similar rocks and fossils are found on different continents.

2. False, its the other way around

3 Pangaea, though many super-continents have formed and fell apart before Pangaea formed.

4. asthenosphere

5. both radioactivity and heat left over from earth´s formation

Answer 3

1. Wagner was a great visionary and dared during his time to speak against the understanding of continents. His hypothesis of continental drift was never rejected but has been subsequently refined to 'Plate Tectonics' and there is now plenty of evidence to support it.
2.False
3.Pangea
4. Asthenosphere
5.Both

Answer 4

# 2. False
Dense material - sinks and less dense material - rises.

#3. Pangaea
