Detailed explanation-1: -Wind is a powerful agent of erosion. Aeolian (wind-driven) processes constantly transport dust, sand, and ash from one place to another. Wind can sometimes blow sand into towering dunes.

Detailed explanation-2: -The correct answer is Wind. The wind is an agent for erosion which is responsible for the formation of sand dunes. Wind erosion (named after Aeolus, the Greek god of winds) is known as aeolian (or eolian) erosion and occurs almost always in deserts.

Detailed explanation-3: -Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form.

Detailed explanation-4: -Wind erosion is also a natural process. The large parallel sand dunes in south-west Queensland, including the Simpson Desert National Park, are the result of wind erosion and deposition over thousands of years. These dunes are constantly moving and roads and tracks can be covered by drifting sands in only a few hours.

Detailed explanation-5: -Answer and Explanation: Wind erosion causes sand dunes as part of a two-part process. First, strong winds blow across the loose sand on the surface of the Earth, including sands found in deserts and beaches. The force of the wind lifts and moves the particles of sand.
