Document Summary

Earth rotates/orbits: includes daily and seasonal cycles associated with changes in solar radiation as, earth"s climate is currently changing due to changes in concentration of gases (i. e. carbon dioxide) Earth"s surface: exchange air more effectively with cooler air in surrounding atmosphere, decrease in temperature with increasing height above surface is known as lapse rate. Large mountain chains (cordilleras) can act to channel movement of air masses. Loss of forests means less absorption of solar radiation but lower heat gain is offset by lower evapotranspirative cooling due to loss of leaf area: outcome may be warmer, drier regional cimate. In temperate zone lakes, seasonal changes in water temperature and density result in seasonal changes in stratification: in summer, epilimnion (surface layer) is warmest and contains active populations of phytoplankton and zooplankton. Underlain by thermocline: zone of rapid temperature decline. Leads to recycling of nutrients that are lost from epilimnion.
