Streams and rivers carry soil and rocks from one location to another. But there is another way for these geological materials to move. Scientists call this process “aeolian transport.” In aeolian transport, winds move small particles of soil or rock over potentially great distances. Geologist Melisa Diaz and her team studied dust in Antarctica to find out if it was moved by aeolian transport. They discovered that the dust matched geological material in Australia. Aeolian transport had carried it from one continent to another, across thousands of miles of open ocean.
