What you'll learn

Key ideas in Living on a Giant Spaceship

  • Water erodes the outer 'cut bank' making it steep
  • Trees curve their trunks to stay upright during slow soil movement
  • Water deposits sediment on the inner 'point bar' making it shallow
  • Sudden events leave jagged, un-smoothed edges on debris
  • Identifying the direction of river migration based on bank appearance
  • Distinguishing between slow geological processes and sudden events
  • High-volume water carries much heavier loads than normal flow
  • Sudden drops in water speed leave large debris stranded in unusual places
  • Cirrus clouds thickening into cirrostratus indicate an approaching warm front
  • Wispy clouds alone are fair weather, but increasing coverage suggests a pressure change
  • Higher clouds signal long-term changes in air masses
  • Lower clouds indicate immediate moisture and local instability
  • Connecting cloud altitude to atmospheric stability and weather timing
  • Vertical growth indicates rising unstable air and high energy
  • Flat, layered clouds indicate stable air
  • Tilt causes the sun's rays to strike at different angles throughout the year
