Thee Enginee: Plate Tectonics andEarthquake Mechanics

To fully grapp how threamakes sculpts landforms, one mutt first understand the framework of plate tectonics. The Earth 's outer shell, known as the lithosphere, is broken into several large and small tectonic plates that float atop thee semi- fluid asthenosfere benefiath. These plates move relativa te to each tell three primary type of boundaries:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Divergent boundaries Xi1; Xi1; FLT: 1 Xi3; Xi3;, were plates move apart;
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Convergent boundaries Xi1; Xi1; FLT: 1 Xi3; Xi3;, were plates collide;

It is the tectonic stresses at these boundaries that accumulate over time until they eth measult thee contricth of rocks, leading to sudden fault movements that removase seismic energy.
