Question

6. How did non-believers in Wegener's theory explain plant and animal distributions in the southern hemisphere?
Dispersal by winds
Dispersal via now-sunken land bridges

7. What finally convinced geologists that the continents did move?
Dinosaur distributions
Lystrosaurus in Antarctica
Mantle convection
Paleomagnetism

9. When a ship passes over seafloor that has a 'reverse' magnetic polarization, how does this effect the magnetic field reading?

The magnetic field is directed east.
The magnetic field is directed south.
The magnetic field is directed west.
The strength of the magnetic field is slightly stronger than usual.
The strength of the magnetic field is slightly weaker than usual.

14. Which sea is an example of rifting forming an incipient ocean?
Baltic Sea
Bering Sea
Black Sea
English Channel
Red Sea

16. How does plate tectonic theory explain the Ural Mountains separating Europe and Asia?
Ancient collision and suturing of Europe and Asia
Eurasia is moving over a hot spot in the mantle
Incipient rifting apart of Europe and Asia
Intraplate orogenesis in Eurasia
The Urals are the one mountain chain that was better explained by older theories.

Answer 1

6. Dispersal via now-sunken land bridges
7. Paleomagnetism
9. The strength of the magnetic field is slightly weaker than usual.
14. Red Sea
16. Ancient collision and suturing of Europe and Asia

Answer 2

6. The animal distribution is the same all over the world. The fossils in S. America and Africa is not proof that the continents were once connected.
7. Perhaps all four. I believe, however, that they are just using plate movement to convince everyone that the earth is old.
9. Slightly weaker. It was wrongly called a reversal. Magnets do not reverse.
14. Not sure. Some cities thousands of years ago were built too close to the beach. As the ocean level rose they were forced to abandon the cities. I forgot which sea the cities were located in. Sorry.
16. Not sure. I'll look this one up later.
