Answer
Wind's suspended load consists of fine particles, including dust and sand, that are carried in the air. These particles can be lifted high above the surface and transported over long distances. On the other hand, wind's bed load refers to larger sand grains that are too heavy to be carried in the air for long distances and are instead moved along the ground through saltation or creep. The bed load travels close to the surface and is responsible for the formation of sand dunes and other wind-shaped landforms.
