plate tectonics, definition of

One of the interrelated components of the Earth's system, the cryosphere is frozen water in the form of snow, permanently frozen ground (permafrost), floating ice, and glaciers. Fluctuations in the volume of the cryosphere cause changes in ocean sea level, which directly impact the atmosphere and biosphere.

• “How CO2 Starvation & Plate Tectonics Caused the Greatest Mass Extinction, the Permian Great Dying”
  The gradual sequestering of CO2 over millions of years gradually dropped CO2 to starvation levels that reduced photosynthesis, causing the "phytoplankton blackout" and Carboniferous Rainforest Collapse, wide spread ecosystem disruptions and a series of...
• UN Advisor Claims ‘climate change is triggering more earthquakes’ – ‘There is growing scientific evidence that climate change increases the risk of such tremors, together with tsunamis and volcanic eruptions’
  Warmists now claim everything caused by AGW: ‘Could it be then, that if we continue to allow greenhouse gas emissions to rise unchecked and fuel serious warming, our planet’s crust will begin to toss and turn once again?’

  ...apparent sea level acceleration may have oscillated about a mean of zero and an amplitude of roughly 0.4 mm/yr/yr.

  ... these findings reveal the hitherto underestimated role played by plate tectonics in the evolution of biodiversity in the oceans over geological time scales.
• Seafloor spreading has been slowing down
  This cycle is called seafloor spreading, and its rate shapes many global processes, including sea level and the carbon cycle. Faster rates tend to cause more volcanic activity, which releases greenhouse gases, so deciphering spreading rates helps contextualize...
