Which feature of the Earth's surface listed below is likely to be moved by wind? A. Soil B. Rock C. Mountain D. Mud

Even though this should be a Geography question, the correct answer is A. Soil.

Wind is characterized as a large scale flow of gasses, in Earth's case, mostly air. The correct answer is soil because it has the smallest particle size of the options. Mud is incorrect because it is soggy and doughy, being hard to move with air. While a rock and a mountain both have high density and bigger size, which would be harder for the wind to move, the soil has a bunch of small sized grains which are lighter and should be easily carried by the wind in smaller portion, especially in areas where there is less plants and roots.
