Wind is the primary factor for causing ripples in the surface of desert sand but water can also be an agent during the rainy season.
wind creates ripples in the sand
A process called weathering
Wind causes sand to ripple in the desert through a process called saltation, where grains of sand are lifted and carried by the wind before settling back down. As the wind direction and speed change, these sand grains accumulate in patterns, creating ripples and dunes. The size and shape of these ripples depend on factors like wind strength, grain size, and moisture content. Ultimately, the dynamic interaction between wind and sand shapes the unique landscape of desert environments.
Wind actions, by deflation (upliftment, transportation and deposition of desert materials like sand and dust from one place to another).
The center of a ripple is called the focal point. This is where the disturbance that creates the ripple originates, spreading outwards in concentric circles.
Sand, sand, and desert sand
A hill of sand in a desert is normally referred to as a dune
The Arabian Desert is the largest sand desert.
I'm pretty sure it's called a sidewinder snake.Might need to look it up.
The largest sand desert is the Arabian Desert in Asia.
I think the answer is called ripple marks
Sand is on the desert.
