Question

1. which of the following statements is true about the theory of plate tectonics?

there is little evidence that the continents were once a supercontinent.
wegeners theory of plate tectonics states that continents move slowly on the surface of earth.
wegeners theory of continental drift disproved the theory of plate tectonics.
it explains how the continents moved and fossil findings are evidence that they were once a supercontinent.

Explanation:

• Plate tectonics theory explains continental movement. Fossils of same species on distant continents support the supercontinent (Pangaea) idea.
• Wegener proposed continental drift (not plate tectonics). Continental drift was a precursor, not a disproof, of plate tectonics. There is much evidence (fossils, geology, etc.) for supercontinent.

Answer:

It explains how the continents moved and fossil findings are evidence that they were once a supercontinent.
