Lesson 1: Rock and Water Cycles

Model cycling of materials through Earth systems.

Learning goals

  • Explain rock cycle processes.
  • Explain water cycle processes.
  • Connect cycles to energy and gravity.

Rock cycle

Rocks change through weathering, erosion, deposition, burial, melting, cooling, heat, and pressure.

Water cycle

Water moves through evaporation, condensation, precipitation, runoff, infiltration, and transpiration. Energy from the Sun and gravity drive the cycle.

Lesson 2: Weather Systems and Resources

Connect air, water, land, and resources.

Learning goals

  • Describe weather system interactions.
  • Identify natural resources.
  • Explain uneven resource distribution.

Weather systems

Weather patterns are driven by unequal heating of Earth, rotation, air pressure differences, and water cycling.

Natural resources

Minerals, energy resources, soil, and groundwater are unevenly distributed because of geologic processes.
