Carbon: Passive rider on the Earth/Space Machine

Earth operates a network of molten upwellings from deep seams in the planet's crust which act to shove tectonic plates across the seafloors where these plates bump into continental land outcroppings. There the spreading plates subduct beneath the continental rims and simultaneously thrust mountains upward from sea level. Such crustal movements continue to alter our global topography today. Atmospheric composition is largely unaffected by these tectonic movements except during volcanic eruptions which emit gasses that are subsequently diffused about the globe by wind action.Space operates a system of radiant inputs to the earth: both continuous cosmic rays from deep space and variable solar rays from our nearby sun. From time to time the sun produces solar winds having magnetic effects that perturb the incoming cosmic rays causing them to vary in intensity. The primary solar rays vary also but to a lesser extent than the solar-perturbed cosmic rays. Atmospheric composition is largely...(Read Full Article)
