Where does the volatile dust called "Calima" come from?
a mine heaps
a saharan air layer
emissions from the engine exhaust gases
a volcanic eruption
The Saharan Air Layer (SAL) is an extremely hot, dry and sometimes dust-laden layer of the atmosphere that often overlies the cooler, more-humid surface air of the Atlantic Ocean. The SAL passes over the Canary Islands where the phenomenon is named "Calima" and manifests as a fog that reduces visibility and deposits a layer of dust over everything.
