Sand dunes
Dunes are formed when windblown sediments pile up behind obstacles like rocks or plants. The wind moves these sediments, causing them to accumulate on the downwind side of the obstacle, resulting in dune formation.
When an obstacle causes wind to slow down and deposit materials, it can create a landform known as a dune. Dunes are formed by the accumulation of sand or other sediments as they are carried by the wind and then deposited behind the obstacle. Over time, these deposits can pile up and shape the characteristic features of a dune.

When an obstacle causes wind to slow down and deposit materials, the materials can pile up and eventually form a dune. Dunes are formed through the accumulation of sand or other sediments carried by the wind and deposited behind the obstacle, such as a rock or vegetation. Over time, these sediments build up, forming characteristic features of dune formations.
it has more rocks because the river has lots of sediments ( pieces of broken rock ) to carry along the river flow. then the sediments pile up into layers and then for many years the layers will harden and turn into a rock. YOUR WELCOME :)

The process described is sedimentation, where sediments accumulate over time due to various geological processes. Compaction is a key part of the lithification process, where sediments are compacted under pressure, leading to the formation of sedimentary rocks. This compaction reduces the volume of the sediments and helps bind them together, ultimately forming solid rock layers.
A windblown pile of snow is called a snowdrift. This occurs when strong winds pick up loose snow and deposit it in a mound-like formation. Snowdrifts can vary in size and shape depending on the strength of the wind and the texture of the snow.
