GLOSSARY FOR LECTURE 08 anaerobic - A biological process that occurs in absence of oxygen. anoxic - without oxygen. bar - unit of pressure equal to a million dynes per square centimeter. Coriolis force - An apparent force caused by rotation of Earth. In Northern Hemisphere winds are deflected to right; in the Southern Hemisphere to left. cyanobacteria - prokaryotic organisms without organized chloroplasts but having chlorophyll. doldrums- Region near equator characterized by low pressure and light shifting winds. eukaryotic - Cells containing nucleus and other membrane-bound organelles. Ferrel Cell - zonally symmetric circulation first proposed by William Ferrel in 1856 as middle of three meridional cells in each hemisphere. greenstone belts - belt of rocks having green hue imparted by chlorite minerals within rocks. Found in Australia, southern Africa, and Canada, and may be found included within igneous and metamorphic rock, Hadley Cell - large circulation pattern in the lower atmosphere distinguished by rising air in equatorial regions and descending air in subtropics. Horizontal flow at surface and aloft closes circulation pattern. hematite - mineral with chemical formula of Fe 2 O 3 horse latitudes - belts of light, variable winds associated with latitudes between about 30 and 35 degrees. impact degassing - vaporization of meteorites on impact with Earth's surface.

intertropical convergence zone - boundary zone separating northeast trade winds of Northern Hemisphere from southeast trade winds of Southern Hemisphere. latent heat - heat that is either released or absorbed by unit mass of a substance when it undergoes change of state, such as during evaporation, condensation, or sublimation. magnetite - iron oxide mineral (Fe 3 O 4 ). metazoans - animals whose bodies consist of many cells, as distinct from Protozoa, which are unicellular polar cell - circulation in high-latitude troposphere characterized by ascending air in subpolar latitudes (50 ° -70 ° ), descending air over pole, poleward motion aloft and equatorward motion near surface. polar easterlies - prevailing winds that blow from high-pressure area of polar highs towards low-pressure area of polar front at around 60 degrees latitude polar high - cold anticyclone that originates in source region for continental polar air. procaryote - cell in which genetic material is dispersed throughout cell in distinction to a eucaryote which has nucleus and other organelles. proterozoic - eon of geologic time from 2.500 to 0.540 billion years ago. photodissociation - splitting of molecule by a photon. pillow basalts -
