Hiekkapinnoitteiden
Hiekkapinnoitteiden, also known as sand dunes, are landforms created by the deposition of sand-sized grains of minerals, rock fragments, or organic materials by wind, water, or ice. They are found in various environments, including deserts, coastal areas, and even in some inland regions. Sand dunes can take on different shapes and sizes, ranging from small ripples to massive formations that can reach heights of over 200 meters.
The formation of sand dunes is primarily driven by wind, which transports sand grains and deposits them
Sand dunes play a crucial role in various ecosystems, providing habitats for numerous plant and animal species.
