Dunes are formed by the accumulation of sand particles carried by the wind. When wind blows across a sandy surface, it picks up loose sand grains and carries them along. As the wind slows down or encounters an obstacle, it drops the sand particles, leading to the formation of dunes. Dunes can also be moved by the wind, a process known as saltation, where sand grains are bounced along the surface of the dune. Over time, dunes can migrate and change shape as a result of wind patterns and other environmental factors. **

Those tiny yellow creatures on your bed are likely dust mites. Dust mites are microscopic insects that feed on dead skin cells shed by humans and animals. They are common in household dust and can thrive in warm, humid environments like bedding. While dust mites themselves are harmless, their feces and body fragments can trigger allergies and asthma symptoms in some people. Regular cleaning and washing of bedding can help reduce dust mite populations. **
