Some fossils from the same species are found in different continents, across sea, these species could not swim so big distances, so it suggests that once the continents were joint and species could walk from America to Africa and other continents.
Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator, it suggests that the glaciers either formed in the middle of the ocean and/or covered most of the Earth. Today glaciers only form on land and nearer the poles, it can be suggested that glaciers were centered over the southern land mass close to the South Pole and the continents moved to their present positions afterwards.
Polar wandering is the movement of the magnetic poles over Earth’s surface through geologic time. It suggests that plates move.
The Gondwana continents glaciation could only have occurred if the continents were joined together since the centres of the glaciers would have been in the ocean if they were not. Also, the continents, such as South America and Africa are similar with jigsaw puzzle.
The plate tectonics theory states that the earth is solid outer crust, the lithosphere, is segregated into plates which further move over the asthenosphere, the melted upper portion of the mantle. Oceanic and continental plates come and joined together, spread apart, and interact at boundaries all over the planet.
Similar fossil plant and animals are segregated by oceans leading to the assumption that they must have lived in adjacent regions when they were alive. Finally, similar rock sequences and mountain ranges could be connected across oceans.
