Practice question · Put in order
Put the self-inflicted Mediterranean erosion cascade in order.
- Malaria arrives and the plain is abandoned
- Marshland spreads across the plain
- Sediment fills the valley floor and blocks drainage
- Slopes are deforested for timber, fuel, and pasture
- Rain strips the exposed soil from the hillsides
Hints
- Clearing the slope has to come before anything can wash off it.
- The sediment ends up where the water slows.
Show the answer
- Slopes are deforested for timber, fuel, and pasture
- Rain strips the exposed soil from the hillsides
- Sediment fills the valley floor and blocks drainage
- Marshland spreads across the plain
- Malaria arrives and the plain is abandoned
Why
The classical Mediterranean did a great deal of this to itself. Erosion looks like a natural process, and a large share of it is a decision taken uphill a century earlier.
