10. What are the important features of a glossopteris? *
A. It provide important evidence for distribution of continental plates.
B. It is occurred in a variety of growth forms.
C. It is a woody, seed-bearing shrub or tree, named after the Greek description of ‘tongue’ – a description of the shape of the leaves.
D. It is found in the Southern Continents.
11. When the continents of the southern hemisphere are re-assembled into the single land mass of Gondwanaland, the distribution of these four fossil types could be? *
A. separated patterns of distribution across continental boundaries.
B. apart from the patterns of distribution across continental boundaries.
C. along circled patterns of distribution across continental boundaries.
D. linear and continuous patterns of distribution across continental boundaries.
12. What does plate tectonic theory predict about the distribution of earthquakes and volcanoes? *
A. They should occur primarily on continents.
B. They should occur primarily in deep ocean basins
C. They should occur primarily along plate boundaries.
D. They should be evenly distributed throughout the Earth.
13. Why does Wegener’s ideas on the continental drift was first rejected by scientist? *
A. He wasn’t able to explain how this drifting took place.
B. Inability to provide adequate explanation of his findings.
C. He could not provide a mechanism for the movement of the continents.
D. He could provide only illogical explanations for the movement of the continent
14. How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it? *
A. by determining the age of rock samples obtained by drilling on the sea floor.
B. by observing eruptions of molten material on the sea floor.
C. by measuring how fast seafloor spreading occurs.
D. by mapping rocks on the sea floor using sonar.
15. How does the seafloor spreading becomes evidence from drilling samples that could determine the age of rocks? *
A. The rocks on the ocean floor moves away from the ridges becoming rocks older.
B. Youngest rocks found near mid- ocean ridges while oldest rocks found far away from mid- ocean ridges.
C. The younger rocks are hard to find while older rocks are seen on the seashore.
D. Rocks are determined by means of its color and shapes.​
