plate tectonics - Coggle Diagram
plate tectonics
effects of plate tectonics
mountain formation
ocean trench formation
volcanoes
continental drift
earthquakes
tectonic plates
include continental and oceanic plates
float on the atmosphere
e.g: pacific plate, eurasian plate
large slabs of the lithosphere
types of plate boundaries
divergent boundaries
forms mid-ocean ridges, rifts
e.g: mid-Atlantic ridge
plates move apart
transform boundaries
causes earthquakes
e.g: san andreas fault
plates slide past each other
convergent boundaries
causes mountains, earthquakes, volcanoes
e.g: himalayas
plates move towards eachother
important terms
seafloor spreading: new crust forms at divergent boundaries
ring of fire: major zone of earthquakes and volcanoes around the pacifc
subduction: one plate sinks under another
plate movements
influenced by: ridge push and slab pull
driven by convection currents in the mantle
theory of plate tectonics
developed from continental drift
supported by:
fossil eevidence
rock formations
seafloor spreading
