Question

small sediments carried high in the air move by __________
a suspension
b saltation
c creep
d carry

Explanation:

Suspension is the process where small, light sediment particles are lifted and carried high in a fluid (like air) over long distances. Saltation refers to particles bouncing along a surface, creep is large particles rolling/sliding along the ground, and "carry" is a general, non-specific term not used for this specific sediment transport process.

Answer:

a. Suspension
