GENERAL GEOLOGY

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

Detailed explanation-3: -Aeolian Transport is the first process of coastal dune formation and involves the movement and weathering of sand particles behind and along the shoreline.

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.
