Physical Systems and Landscapes

Learners read landscapes as records of process and time. They examine the evidence for plate tectonics — magnetic stripes, ocean-floor ages and the Hawaiian hotspot chain — and calculate plate speeds; link rock type to landscapes such as karst; explain river, glacial, coastal and desert landforms process by process; and use rates of change to reconstruct how a landscape formed.

What learners will discover

  • Use evidence (magnetic striping, ocean-floor ages, earthquake depths, hotspot chains) to explain plate movement and calculate plate speeds.
  • Explain the rock cycle and how rock type and structure shape landscapes such as karst.
  • Explain river and glacial landforms using specific erosional and depositional processes and rates.
  • Explain coastal and arid landforms and reconstruct a landscape's history from evidence.
