INDIAN GEOGRAPHY

Detailed explanation-1: -In short, a dune is a wind or water-built hillmade of dry or wet soil. The wind raises or moves sand from one location to another as it blows. When the wind stops blowing, it collects in a single area, forming hill-like structures. These are called Sand dunes which are found in deserts.

Detailed explanation-2: -What is a sandstorm? A sandstorm refers to a high amount of wind occurring in sandy areas, usually in deserts, where the wind speed is able to lift the top layer of sand from the ground, and push it in every imaginable direction.

Detailed explanation-3: -A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface.

Detailed explanation-4: -Wind Causes Weathering and Erosion In dry areas, wind is a powerful cause of weathering and erosion. Here the wind is eroding sand between the plants. You learned how water changes Earth’s surface through weathering, erosion, and deposition. Wind also causes these processes.

Detailed explanation-5: -Sand and dust storms usually occur when strong winds lift large amounts of sand and dust from bare, dry soils into the atmosphere. Over the last decade, scientists have come to realize the impacts on climate, human health, the environment and many socio-economic sectors.
