	Sand can form dunes, which are mounds of sand piled up from the wind. They migrate with the prevailing wind, sand grains picked up on the windward side and deposited on the leeward side. They are often in a state of flux and do not remain in the same location. This makes it difficult for any vegetation to take root and grow. Especially since water drains so easily through sand and sandy soil mixtures. Even if there are sufficient rains, the sand/soil may not hold water for long. Some sandy locations have especially arid environments, like the Sahara desert or the Gobi desert. Other locations have a much more moderate climate; these places are more likely to develop vegetation. When vegetation does manage to take root, it begins to foster a small ecosystem.

	Some arid desert dune plant types include perennial grasses like ''Pleuraphis rigida'', some perenial herbs like ''Artemisia filifolia'' or shrubs like ''Ephedra trifurca'' and ''Eriogonum deserticola''. In more humid areas, sand dunes can be populated by species of dune-grasses, like ''Ammophila breviligulata'', ''Uniola paniculata'', ''Calamovilfa longifolia''. As dune vegetation stabilizes, it may form successional ecosystems like prairies, with occasional shrubs and trees, which may eventually form more forested communities. [7] The Sleeping Bear Dunes of Michigan support populations of cottonwood trees, which have a fast growth rate and a very connected root network that helps hold sand in place.

	Sand is the result of the breakdown of a variety of inorganic and organic materials. It is broken down via physical and chemical weathering. Physical processes can be driven by water, air, or other sand grains. Sand can be weathered chemically by minerals reacting with water, or other substances. Physical and chemical weathering tend to be a bit indistinguishable from each other when it comes to the formation of sand.

	Many different locations around the world are known for their distinctly colored sand, like pink sand from Utah, black sand from volcanic areas, green sand from Hawaii, etc. These unique sands all have compositional reasons for their specific color.

Pink sands are often from single-celled [[organisms]] ''Homotrema rubrum'', which possesses red/pink shells.

These 3 combine in distinct ratios to make different soil types, like loam, silt loam, sandy clay, etc. The soil classification can be determined by feel, via flowchart, or by the hydrometer method.

	Sand can form dunes, which are mounds of sand piled up from the wind. They migrate with the prevailing wind, sand grains picked up on the windward side and deposited on the leeward side. They are often in a state of flux and do not remain in the same location. This makes it difficult for any vegetation to take root and grow. Especially since water drains so easily through sand and sandy soil mixtures. Even if there are sufficient rains, the sand/soil may not hold water for long. Some sandy locations have especially arid environments, like the Sahara desert, or the Gobi desert. Other locations have a much more moderate climate, these places are more likely to develop vegetation. When vegetation does manage to take root, it begins to foster a small ecosystem.

	Some arid desert dune plant types include perennial grasses like ''Pleuraphis rigida'', some perenial herbs like ''Artemisia filifolia'' or shrubs like ''Ephedra trifurca'' and ''Eriogonum deserticola''. In more humid areas, sand dunes can be populated by species like ''Ammophila breviligulata'', ''Uniola paniculata'', ''Calamovilfa longifolia''. As dune vegetation stabilizes, it may form successional ecosystems like prairies, with occasional shrubs and trees, which may eventually form more forested communities. [7] The Sleeping Bear Dunes of Michigan support populations of cottonwood trees, which have a fast growth rate and a very connected root network that helps hold sand in place.
