which piece of evidence did Alfread Wegener original theory of continental drift   have acress to A seafloor spreading at mid ocean ridges, B reversing paleomagnetism in rocks on the ocean floor, C evidence of ancient tropical swamps in cold regions of north American, D a seafloor that was geologically active with earthquakes volcanoes and mountains  chains

GPT-4o mini · Answer

Alfred Wegener's original theory of continental drift was primarily supported by evidence such as:

C. evidence of ancient tropical swamps in cold regions of North America.

Wegener presented various types of evidence for his theory, including the fit of continental coastlines, fossil correlations, and geological similarities across continents. The existence of ancient tropical swamps or coal deposits in now cold regions was one of the pieces of evidence he used to support his idea that continents have moved over geological time.

The other options (A, B, and D) relate more to later developments in plate tectonics and seafloor spreading, which were not part of Wegener's original theory.
