Español: Este esquema del ciclo del carbono muestra el almacenamiento y los cambios anuales del s entre la atmósfera, la hidrósfera y la geósfera en gigatones, o miles de millones de toneladas, de carbono (GtC). La quema de combustibles fósiles libera cerca de 5.5 mil millones de toneladas de carbono al año en la atmósfera.
Carbon cycle schematic showing the movement of carbon between land, atmosphere, and oceans in billions of tons (gigatons) per year. Yellow numbers are natural fluxes, red are human contributions, and white are stored carbon.
The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. [1]
The Lewis structure of a carbon atom, showing its four valence electrons. Carbon is a primary component of all known life on Earth, and represents approximately 45–50% of all dry biomass. [1]
Carbon sequestration is part of the natural carbon cycle by which carbon is exchanged among the biosphere, pedosphere (soil), geosphere, hydrosphere, and atmosphere of Earth.
This figure describes the geological aspects and processes of the carbonate silicate cycle, within the long-term carbon cycle. The carbonate–silicate geochemical cycle, also known as the inorganic carbon cycle, describes the long-term transformation of silicate rocks to carbonate rocks by weathering and sedimentation, and the transformation of carbonate rocks back into silicate rocks by ...
Pine-oak forests are the main plant community in the corridor, with species of pine, oak, and oyamel (fir) as the predominant trees.. The Chichinautzin Biological Corridor is a protected natural area with a remarkable diversity of habitats and species due to its geographic and climatic conditions.
The first experiments indicating that some plants do not use C 3 carbon fixation but instead produce malate and aspartate in the first step of carbon fixation were done in the 1950s and early 1960s by Hugo Peter Kortschak and Yuri Karpilov.
