Deposition
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 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.
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.
because they are duh
Fore dunes and back dunes but mostly fore dunes.
Sediment deposits on dry land can form various landforms such as sand dunes, alluvial plains, and deltas. Over time, these deposits can accumulate and be cemented together to form sedimentary rocks.
They were both formed by wind erosion.
Barchan dunes are solitary crescent dunes formed on a flat, hard ground with limited supplies of sand and vegetation. Transverse dunes are a series of long ridges that are found in areas that have a lot of sand but sparse vegetation.
