question 1 (1 point)
what initial observation led alfred wegener to believe all landmasses were once connected?
a the number of deserts is evenly spread across continents
b glossopteris fossils look different in different countries
c countries look like they could fit together like a jigsaw puzzle
d discovery of magnetic stripes on the ocean floor proved the poles have reversed

Explanation:

Alfred Wegener noticed that continents' shapes (like Africa and South America) could fit together like a jigsaw puzzle. This was one of the initial observations leading to his theory of continental drift. Glossopteris fossils (option b) were evidence supporting the theory (same plant fossils on different continents), but the question asks for the initial observation. The number of deserts (option a) and magnetic stripes (option d) are not the initial observations for Wegener.

Answer:

c. Countries look like they could fit together like a jigsaw puzzle
