In the early 1900s, alfred wegener noticed that some of earth's continents looked like they might fit together like a jigsaw puzzle. he also observed that the continents that looked like they fit together had similar plants, animals, and rock formations. from this evidence, wegener reasoned that earth's continents were all once a part of one big supercontinent. what type of scientific thinking did wegener employ to develop his theory?

The theory developed by Wegener that the continents of the Earth were once a part of a single big super-continent is based on his observations that these continents fir together as a part of the jig-saw puzzle. And these observed continents have similar flora and fauna along with similar rock formations. Such a derivation of theory from observations is an inductive reasoning.

Hence, the answer is 'inductive reasoning'.
