These “singing” sands are caused by vibrations in the sand and require a combination of round sand grains, silica content, and humidity and emit a variety of sounds. A dune can exist in a desert like the Namib Desert or on the coast of Lake Michigan in Indiana. Deserts worldwide are caused by similar patterns of wind, temperature, and moisture. #> #>(Q?) Where might you find sand dunes? What properties about sand dunes allow them to “sing”? What sort of temperature and moisture would lead to a desert? How does wind influence desert formation? #> #>---(1) Land Cover Map with Ribbon of Labels--- #> #>This map shows where deserts and dunes might be found along with other types of land cover. #> #>---(2) Koppen-Geiger Climate Classification 2007--- #> #>Singing sands are more likely to be found in certain biomes, and this map shows how those biomes are distributed around the world. #> #>---(3) FIM Forecast Model: Wind Streamers Real Time--- #> #>Since singing sands are often caused by winds, this dataset gets us thinking about the wind patterns in the atmosphere where the weather forms.
