Benchmark 4C The Physical Setting: Processes
that Shape the Earth
Grades 6-8, page 73
Human activities, such as reducing the amount of forest cover, increasing
the amount and variety of chemicals released into the atmosphere, and intensive
farming, have changed the earth's land, oceans, and atmosphere. Some of
these changes have decreased the capacity of the environment to support
some life forms.
Benchmark 5E The Living Environment:
Flow of Matter and Energy
Grades 9-12, page 121
At times, environmental conditions are such that plants and marine
organisms grow faster than decomposers can recycle them back to the environment.
Layers of energy-rich organic material have been gradually turned into
great coal beds and oil pools by the pressure of the overlying earth. By
burning these fossil fuels, people are passing most of the stored energy
back into the environment as heat and releasing large amounts of carbon
dioxide.
Benchmark 8C The Designed World: Energy
Sources and Use
Grades 6-8, page 194
Different ways of obtaining, transforming, and distributing energy
have different environmental consequences.
