The theory of plate tectonics
The theory of Pangaea was that the continents were once together and then were drifted apart due to plate tectonics.
Alfred Wegeners 1912 theory of Plate tectonics and continental drift.
Plate tectonics (This is the mechanism), the theory is continental drift.
North America and Europe are moving farther apart because of the theory of plate tectonics.
Continental Drift, unless you are looking for a technical term for something else. Actually, is it theory or is it reality?
Why is South America and Africa moveded apart?
Plate Tectonics has some continents moving apart (e.g. North America and Europe) and others moving together or colliding (e.g. India and Asia). The movement is complex as it is driven by convection cells in the mantle.
yes. because of the sea-floor spreading making Africa and South America drift apart even more
North America
North America borders South America. Apart from that, it is surrounded by ocean.
sea floor spreadingThe continents of South America and Africa started to spread apart when the mid-Atlantic ocean ridge started creating new oceanic crust which pushed the continents apart.
