Question 7 • TPS EdX Biology

Which source of evidence did Wegener use to support his theory of continental drift?

Answer
A
glaciers found near the poles
B
satellite mapping of the tropical islands
C
fossils found on Earth
D
magnetic fields of Earth

Explanation

Wegener supported continental drift by pointing to identical fossils found on continents now separated by oceans. These fossil matches suggested the continents were once joined, allowing the same plants or animals to live across them. “Fossils found on Earth” is the correct choice; satellite mapping and measurements of Earth’s magnetic field were not evidence available to Wegener.
