Students evaluate how slow changes on the earth over geologic
time can yield dramatic effects, such as the growth and
regression of mountains, the ebb and flow of oceans, and the
emergence and disappearance of entire continents. Students also
examine the rock cycle and characterize primary types of rock,
glaciation and weathering, and prominent minerals. Practical
applications of these natural wonders such as metals, industrial
minerals, and fossil fuels are also introduced. This class
examines the relationships between organisms and their
environments. Students construct a picture of the Earth as a
living organism, with each element holding an important role as
part of an interconnected whole. Topics covered include the flow
of energy through ecosystems in food webs, the importance of
biodiversity, the affect of climate on regional ecosystems, the
process of growth over time after disturbances in an area, plant
and animal habitats and adaptations, and the changing
relationship of human beings to the Earth. S
