Question

wegeners hypothesis of continental drift was finally confirmed and supported by which of the following discoveries? 1. fossils from the same reptile found on two continents. 2. evidence supporting the idea of sea - floor spreading. 3. continental coastlines that fit together. 4. the formation of mountain ranges such as the himalayas #s 1 and 3

Explanation:

Wegener's continental drift hypothesis was initially based on observations like matching continental coastlines (e.g., South America and Africa) and similar fossils (like the reptile Mesosaurus) on different continents. Sea - floor spreading evidence (which came later with plate tectonics) and mountain - range formation (like the Himalayas, due to plate collision) are more related to plate tectonics theory.

Answer:

1. fossils from the same reptile found on two continents; 3. continental coastlines that fit together
