Question #1
Which of the following lines of evidence did Alfred Wegener use to support the concept of drifting continents?
A.   The composition of meteors from outer space. Evidence of glaciers in areas that are now tropical. The pattern of geologically similar mountain belts on different continents.
B.   The composition of meteors from outer space. The pattern of geologically similar mountain belts on different continents. The distribution of fossils of various species.
C.   Evidence of glaciers in areas that are now tropical. The pattern of geologically similar mountain belts on different continents. The distribution of fossils of various species. The way the shapes of the continents fit together like pieces of a jigsaw puzzle
D.   The way the shapes of the continents fit together like pieces of a jigsaw puzzle. The composition of meteors from outer space. The pattern of geologically similar mountain belts on different continents.
Question #2
What piece of evidence supports Wegener's hypothesis of continental drift?
