Question

Stationary, long and narrow sand-ridges which grow parallel to the direction of the prevailing wind and remain in a fixed position.

Options

• Dunes

• Sand Dunes

• Barchans

• Seifs

Answer 1

Seifs

Explanation:

Seifs are stationary, long, and narrow sand ridges that form parallel to the direction of the prevailing wind. They remain in a fixed position because they are shaped by strong, steady winds blowing from one direction over a long period of time. Seifs typically occur in areas with limited sand and are characterised by their parallel alignment with the wind direction.
