Sand dunes are fascinating geographical features that have been formed over millions of years by the forces of wind and water. Spread all over the world, they are an important part of the natural landscape of many regions. In North America, sand dunes can be found in various locations, but the largest ones are particularly impressive and draw visitors from all over the world.
Understanding Sand Dunes
Sand dunes are hills of sand that form when wind and water move grains of sand from one place to another. They can be found in coastal areas, deserts, and other regions with dry climates. Sand dunes come in different shapes and sizes, and they can be formed by different types of winds, including those that blow from the sea or those that come from the interior of a continent.
