A Sand Dune is a small ridge of hill of sand found in a desert or on top of a beach. When they form on a beach, they are typically above the normal maximum reach of the waves. They form from millions of finely divided sand particles that are blown by the wind and get deposited against some obstacle such as a piece of drift wood, bush or rock. Sand dunes are formed due to the earth’s erosional and depositional forces. The sand that results in the formation of sand dunes is eroded from rocks by physical and chemical processes such as wind and water. The erosion leads to accumulation of sand. Strong winds pick up the sand and transport it (typically slightly above the ground) to another location.
DID YOU KNOW
Sand dunes are some of nature’s most scintillating creations. These eye-catching land masses are found around the globe in different climatic conditions. They are not only limited to deserts, but can form in any landscape on the earth’s surface provided the conditions are right. Every sand dune is formed as a result of the interaction between the wind and soil in the form of sand grains.
Sand dunes are able to migrate. This gives them a sense of liveliness. However, migration of sand dunes is not received well by the locals as it endangers local towns and agriculture. In a country like China, sand dunes have experienced monumental migrations to nearby villages. The villagers have mitigated this threat by erecting fences to arrest these sand dunes. Better still, most people go the extra mile of drenching the sand dunes with crude oil to prevent their migration. Some areas have even reported collision of migrating sand dunes, leading to massive sand dunes. There are many ways thrill seekers can explore sand dunes, for example, sliding down the dunes, Bird viewing in wetlands, skiing, sand boarding or just sledging on the sand slopes. Sky divers or those on airplanes experience the true beauty of sand dunes.
