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
