earthquakes usually but also tsunamis and stuff like that
plate tectonics
Plates tectonics
Plate tectonics is the combination of the seafloor spreading and continental drift. When Alfred Wegner described this process it was rejected due to lack of evidence. Since, we have discovered new evidence and proven his theory true.
Three evidence that supports Harry Hess theory of Seafloor Spreading is; 1. Paleomagnetism. 2. Plate Tectonics. 3. Polar Wondering and Polar Reversal.
Plate tectonics led to the theory of Pangaea.

"Evidence". There's no special term to distinguish evidence supporting one theory in science from evidence supporting any other theory in science.
Plate tectonics is the combination of the seafloor spreading and continental drift. When Alfred Wegner described this process it was rejected due to lack of evidence. Since, we have discovered new evidence and proven his theory true.
Theories can be changed or rejected if and when the scientific evidence no longer supports the theory.

At the time when this theory was a-brewing, it was difficult to provide conclusive data and evidence.
The theory of plate tectonics has succumbed to the newer theory of continental drift. Scientists believe this theory today due to three main factors. First, the continents appear to fit together. When the continental shelves, as opposed to just the continents, are placed together, the fit appears uncanny. Second, the distribution of fossils is consistent with continental drift. Lastly, glacial deposits once covered parts of the earth that are currently tropical.ANSWER: The plate tectonics theory is relatively new and formulated only in the 1960s. The evidence listed above in the first answer can only support the continental drift theory which was developed by Alfred Wegener in 1912. Evidence that can support the plate tectonics theory are the age, depth of oceanic sediments, volcanic activity, geothermal gradient, gravity anomalies, paleomagnetism and seismologic evidence. If you are answering an exam question on evidence supporting plate tectonics, evidence supporting continental drift theory should only come later in your answer and should not be given too much emphasis, for the plate tectonics theory involves more than just the continental crust drifting around and cannot support the main hypotheses of the plate tectonics theory.
