  • On human timescale (101 years), we can directly observe only a minuscule segment of the geotectonic weathering cycle and measure its rates mostly as one-way ocean-ward fluxes of water-borne compounds.

    Global material cycles

  • Today's oceans and continents are thus transitory features produced by incessant geotectonic processes that are energized by three sources of the earth's heat: energy conducted through the lithosphere from the underlying hot mantle, radiogenic decay of heat-producing crustal elements, and convective transport by magmas and fluids during orogenic events.

    Global material cycles

  • Human actions are of no consequence as far as the geotectonic processes are concerned, but they have greatly accelerated the rate of weathering due to deforestation, overgrazing of pastures, and improper crop cultivation.

    Global material cycles

  • The other extreme involves slow weathering of terrestrial carbonates, their dissolution, river-borne transport, and eventual sedimentation in the ocean, and the element's return to land by geotectonic processes.

    Global material cycles

  • Inevitably, these grand geotectonic cycles had an enormous impact on the evolution of life.

    Global material cycles

  • Second, all of my life I have made a profound study of geognosy and geotectonic geology.

    The Desert Valley

  • Global sea level changes are thought to be caused by geotectonic and glacial phenomena.


  • Due to its geographic location and geotectonic characteristics, Costa Rica is exposed to a large variety of natural hazards, including floods, hurricanes, earthquakes, volcano eruptions, and landslides.
