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.

Why do the rocks located in stream beds are smooth?

Rocks in stream beds can become smooth due to a process called abrasion. As water flows over the rocks, it carries sediment and particles that constantly rub against the rocks, wearing them down and making them smooth over time. The friction caused by the movement of water and sediment helps polish the surface of the rocks.


Why might you find smooth rocks on a beach?

Smooth rocks on a beach are often the result of continuous erosion caused by water and sand rubbing against the rocks over time. The motion of waves can wear down the rough edges of the rocks, making them smooth.


Does erosion break down rocks?

yes wind and soil erosion both contributes to breaking down of rocks.You can google it and see the pictures of beautiful rocks have been shaped due to wind erosion.and water erosion breaks down the rocks and even make its surface smooth.


Which causes rocks in a stream to to be smooth?

Rocks in a stream become smooth due to the constant force of flowing water wearing down their rough edges over time. The friction and impact from water flow results in abrasion, breaking off small particles and gradually shaping the rocks into a smoother surface.


What causes rocks in a stream to be smooth is it weathering?

Rocks in a stream become smooth through a process called abrasion, where the sediments carried by the water wear down the rocks over time. This continuous rubbing and grinding against each other in the stream smoothens the surface of the rocks.


How do sedimentary rocksget smmoth under water?

Water will smooth out all types of rocks because over time, the movement of other small particles carried along by the water strikes larger rocks in the water, wearing down their sharper edges and points.


Why do you find smooth rounded rocks at the sea shore and the rivers?

Sediment carried by the river acts as an abrasive against the rocks on the bottom of the river. Rocks are also continually bounced into each other, which also serves to gradually knock off rough edges, making them smoother and rounder.


What causes rocks to be smooth?

By weathering which is the gradual wearing away of something. In this case rocks can be weathered by water (current in a large water source or heavy rains) and even wind and other things such as acid rain. Hope that clears things up!


Why rocks are smooth in water?

Rocks become smooth in water due to a process called abrasion, where they are constantly rubbed against each other and other materials, such as sand and sediment, while being transported by flowing water. This continuous friction gradually wears down sharp edges and rough surfaces, resulting in a smoother texture over time. Additionally, the tumbling motion of rocks in streams and rivers further contributes to their polished appearance.


Why are some rocks smooth and others are not?

Rocks can become smooth through processes like erosion, where constant rubbing or flowing water wears down their surfaces over time. On the other hand, rocks that are not smooth may have experienced less weathering or have a composition that is more resistant to erosion, resulting in a rougher texture. Factors such as the type of rock, environment, and exposure to weathering elements play a role in determining whether a rock ends up smooth or not.


What were the smooth rounded rocks that helped dinosaurs digest and grind their food?

Gastroliths were the smooth, rounded rocks that dinosaurs ingested to help them digest and grind their food. These rocks were swallowed and moved around in the stomach to break down tough plant material.
