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.

The "sand dunes and deltas" are similar to that they are both "formed by weathering".
deltas
No, they are examples of deposition, not erosion.

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.
Sand dunes and deltas are different in their formation and environment. Sand dunes are primarily formed by the accumulation of sand through wind action in arid or coastal regions, creating mounds or ridges. In contrast, deltas are formed at the mouth of rivers where sediment is deposited as the river flows into a larger body of water, typically creating a fan-shaped landform. While both are shaped by sediment movement, their locations and the processes that create them are distinct.
