DIVE Earth Science Lesson 3.2
Matthew 5:13 - ANSWER- You are the salt of the earth.''
1 Petagram = - ANSWER- 10¹⁵ grams
1 Gigaton = - ANSWER- 10⁹ metric tons
1 Petagram = - ANSWER- 1 Gigaton
bicarbonate buffer system - ANSWER- Reversible reactions between carbon dioxide
(CO2), carbonic acid (H2CO3), bicarbonate (HCO3-) and carbonate (CO32-) designed
to balance acid levels in natural waters.
biogeochemistry - ANSWER- The scientific discipline involving study of chemical,
physical, geological, and biological processes and reactions governing the composition
of the natural environment.
carbon budget - ANSWER- The sum of all exchanges (release and consumption) of
carbon compounds from the world's carbon sources and sinks.
carbon cycle - ANSWER- The combined processes, including photosynthesis,
decomposition, and respiration, by which carbon as a component of various compounds
cycles between its major reservoirs: the atmosphere, hydrosphere, lithosphere, and
living organisms.
denitrification - ANSWER- Process where certain anaerobic bacteria convert nitrate
(NO3-) to nitrogen gas (N2), using the oxygen from the nitrate as their oxygen source.
inorganic carbon - ANSWER- Refers mainly to carbonate minerals such as limestone
and dolomite, but may also refer to carbon dioxide. Contrast with organic carbon.
