Landforms are geological or terrain features that are markedly different from the surrounding area, such as mountains, canyons, rivers; and to greater effect, oceans and contintents.
There is a single known continent, the 'Red Line' which encircles the whole planet from pole to pole. Apart from this, the only known landmasses are simply referred to as 'islands'.
Continental drift, sea floor spreading, glacial striation, jigsaw fit of the continents, geological matches on different contintents (such as type of rock or fossil found) ,earthquakes, and volcanoes led to the theory of plate tectonics.
