Deposition
No, they are examples of deposition, not erosion.
Both form weather dune is has sand delta water
deltas
The "sand dunes and deltas" are similar to that they are both "formed by weathering".
Deltas and dunes are alike in a couple ways. One way is that they were both formed by the process of moving sand. Another way is that they can be both found near, under, or above water.
Erosion and Depositionerosion causes dunes and valleysdepostion causes deltas
Deltas are formed by the deposition of sediment carried by rivers, dunes are shaped by the wind through the accumulation of sand grains, and canyons are typically carved out by the erosive force of flowing water over time.
some examples are sand dunes,mudslides,or earthquakes.
Examples of geologic deposition include the accumulation of sediment in river deltas, the formation of carbonate rocks like limestone from the remains of marine organisms, and the deposition of volcanic ash from volcanic eruptions settling on land or in bodies of water.
Huge piles of sand are called sand dunes. Sand dunes typically form in deserts or coastal areas where there are strong winds that shape and move the sand into these large structures.
There are only two sand dunes in Michigan. The two sand dunes are Sleeping Bear Dunes and Sliver lake sand dunes.
