The diagrams below show how sand dunes are formed. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The illustration shows the process of how sand dunes are formed. In general, dunes appear when wind moves sand and drops it in some places. Step by step, the sand builds up and becomes higher. At first, the wind blows and carries dry sand particles. Some of them stop on wet sand because they are […]

The illustration shows the process of how sand dunes are formed. Overall, dunes are created when wind transports loose sand particles and deposits them in certain areas, gradually building up into elevated landforms. This process typically occurs in deserts or coastal regions. At the initial stage, strong winds lift dry sand grains and move them […]

The picture depicts the process of sand ridge formation. Overall, this process includes three main stages, starting with the movement of sand particles caused by strong wind from dry to wet regions, and ending with the formation and stabilization of large dunes thanks to the wind strength. At the first stage, wind blowing across dry […]

The picture depicts the process of sand ridge formation. Overall, this process includes three main stages, starting with the movement of sand particles caused by strong wind from dry to wet regions, and ending with the formation of a mass hill of sand. At the first stage, gentle wind from coastal areas brings sand grains […]
