There are three types of platonic movements on the Earth's surface:
Conservative - When the plates slide against each other. This may cause earthquakes.
Destructive When the plates move against each other. This may cause both earthquakes and volcanoes to erupt, by the cause of the Oceanic plate and the Continential plate causing friction once the Oceanic plate slips under the Continential.
Constructive - When the plates move away from each other. This may cause volcanoes to erupt as it opens up the surface from deep underground.
Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.
