Hello,
I read the following passage followed by a question. Please help me solve it.

Running, sailing and flying are natural ways of moving about as animals, birds and fishes do. But the hovercraft does not run on land, sail on water or fly in the air. If we wish to describe its motion, we must say that it runs on the air. It forms and air cushion under it and then crawls forward on this cushion. The hovercraft is described as an amphibious vehicle because it can move over land, as well as over water.

Give synonym for ‘describe’.
