Why are the rocks found in rivers and on beaches smooth?
because of water
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.
What is physical abrasion?
Water abrasion changes the physical conditions of rocks, cliffs and along shore lines.The reason why rocks are so smooth when you take them out of the water is because of water abrasion, the water is slowly taking sediments from the rocks while the water is passing through and makes smooth.
If the Colorado River formed the Grand Canyon why are the rocks so jagged when they should be smooth from the force of the water?
Not all rocks are jagged. However the evolution of the river is continuous and 'rocks' are being broken-off all the time by the water, erosion, weather etc. Of course as 'rocks' are moved along by the force of the water that can make them 'jagged'.
Are igneous rocks smooth?
They may be smooth and others may be rough. Smoothness/roughness is not a defining characteristic for igneous rocks.
What causes rocks on the beach to be smooth?
By weathering. The water currents weather the rocks leaving them smooth.
What cause rocks in a stream to be smooth?
flowing water
Smooth rocks that have been worn down by water?
Conglomarate
Why are the rocks found in rivers and on beaches smooth?
because of water
When water moves on top of rocks what do the rocks become?
Erosion causes them to become smooth from wear.

How do rocks on the beach become smooth?
form the sand & water moving it
Are the rocks in cape cod smooth?
why are most of rocks extremely smooth

Why does rock tend to become rounded?
A lot of rocks have sat in water at one time or another, and flowing water erodes minerals, giving rocks a smooth, rounded shape over time.
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!
When comparing rocks found in a river why would some feel rough and others feel smooth?
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.
