Study Notes

Global Landforms: Plate Tectonics

Definition and Theory

  • Plate tectonics is a scientific theory that describes the movement of the Earth's lithosphere (outer layer)
  • The theory proposes that the Earth's surface is divided into large plates that move relative to each other

Key Components

  • Lithosphere: the outermost solid layer of the Earth, broken into several large plates
  • Asthenosphere: the more fluid layer beneath the lithosphere, allowing for plate movement
  • Plates: large, rigid slabs of the lithosphere that fit together like a jigsaw puzzle

Plate Boundaries

  • Divergent boundaries: where plates move apart, new crust is formed, and magma rises to fill the gap
  • Convergent boundaries: where plates collide, resulting in subduction (one plate is pushed beneath another) or collision (plates push against each other)
  • Transform boundaries: where plates slide past each other horizontally

Processes and Landforms

  • Seafloor spreading: the process of new oceanic crust being created at mid-ocean ridges
  • Continental drift: the movement of continents across the Earth's surface
  • Mountain building: the formation of mountain ranges through plate convergence
  • Volcanic activity: the formation of volcanoes at plate boundaries
  • Earthquakes: the result of plate movement and stress buildup at plate boundaries
