Question 28 1 pts
How did the geosynclinal hypothesis explain similar fossils on continents separated by large ocean basins?
Continents were once together.
Ephemeral land bridges that appeared and disappeared between continents. Subduction created volcanic arcs that were used by plants and animals.
These were marine fossils that could be easily dispersed without needing continental motion.
What was the foundation for the geosynclinal hypothesis?
Continents only moved vertically.
Continents were displaced by an inflating planet.
Continents were in motion, and were pushed around by convection currents. Continents were in motion, but ploughed through oceanic crust.
Question 29 1 pts
What statement about coastlines is correct?
Coastlines are fixed and do not change.
Coastlines move oceanward during sea level rise.
Coastlines are only affected by global sea level change.
Coastlines do not represent the edge of the continents, and are therefore not used in
