(2014) Lesson 4 (1 hour) Key idea 6.3 A balanced carbon cycle is important in sustaining other systems but is increasingly altered by human activities. Suggested learning objectives Identify changes in atmospheric carbon concentrations. Sketch and annotate a simplified greenhouse effect diagram. Skills objectives To analyse and interpret graphs outlining 6.3a The concentration of atmospheric carbon (carbon dioxide and methane) strongly influences the natural greenhouse effect, which in turn determines the distribution of temperature and precipitation.
