Lesson Details
Key learning points
- Tuvalu is a low elevation coastal zone.
- Building coastal defences for small island nations can be challenging due to their low elevation.
- The residents of Tuvalu could become displaced as a consequence of climate change.
- A displaced person is someone who is forced to move due to something outside their control such as flooding.
Common misconception
That sea level is constantly the same and that elevation is the same as height in general.
Sea level changes with the tides; the measure that we use as a baseline is the mean (average) sea level. This is used to calculate elevation of geographical features; sea level is taken as zero and every 1 metre in height is 1 metre above sea level.
