Plate tectonics theory took decades to be accepted because choose one: climate, fossil distributions, and land shape offered conflicting evidence. most of wegener's ideas turned out to be wrong. wegener couldn't explain how continents moved. his research was not well known in the scientific community.

The fact is wegner research lay the foundation stones for the understanding of the plate tectonic theory and later on modified by other scientists.

Explanation:

Alfred Wegener's research was based on his findings on the earth's surface at that time based on his beliefs, and the researches and theories he came across.  Some of the factors that he named were similar climates found across all the continents which were once the part of the same Super landmass Pangaea. Apart from that the Jigsaw fit puzzle of the two landmasses have similar indented coastlines and similarities in their structure and composition of rocks  , and the fossil evidence is clear enough to prove that bothe landmass had similar type of environment and that drifting away created the gaps in their environment and hence the flora and fauna were found to present at both the places. His research lays the background for the formation of earth plates and after which the theory of seafloor spreading given by Harry Hess from his geodetic survey showed tat continental landmasses moved dut the spread effects of mid-oceanic ridges. Hense his theory is partly accepted.
