Rocks at the bottom of a river are smooth and flat due to the constant erosion and abrasion caused by the flowing water. As water moves over the rocks, it carries sediment and debris that collide with the rocks, gradually wearing down their rough edges and surfaces. Over time, this process results in the rocks becoming rounded and flattened. Additionally, the continuous movement of the water helps to sort and polish the rocks, enhancing their smooth texture.
Rocks found in a river bed are typically rounded and smooth due to the erosion caused by the flowing water. These rocks are often composed of hard, durable materials like quartz, granite, or basalt.
Rocks found at the bottom of a stream are typically called streambed rocks. These rocks can vary in size and composition, and their presence can influence the flow and ecology of the stream. Common types of streambed rocks include quartz, sandstone, and granite.
because of water
At a bottom of a lake, a river delta, an ocean, or similar location where further movement is restricted or slowed down.
Sedimentary rocks, such as sandstone and conglomerate, are commonly found at the mouth of a river. These rocks are formed from the accumulation and compression of sediments carried by the river over time.

Wet rocks.
River rocks, because have smooth edges.

Very smooth rocks are called "polished rocks" or "river rocks" due to the smooth texture achieved from erosion in water bodies like rivers and oceans.
Rocks found at the bottom of a stream are typically called streambed rocks. These rocks can vary in size and composition, and their presence can influence the flow and ecology of the stream. Common types of streambed rocks include quartz, sandstone, and granite.
Some feel smooth because it has been eroded away by the current of the water for a very, very long time. The more rough rocks have not been succumb to as much erosion, therefore it is not smooth yet.
Essentially, the only types of rock that can stand up to this type of erosion are igneous and metamorphic rocks. I am not certain there is a technical or scientific term for this type of rock, but the colloquial or "slang" term for them is river rocks.
wet ones
rocks are there
In rock layers, the oldest rocks are typically found at the bottom. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are deposited first and are at the bottom, while the youngest rocks are at the top.
