What causes rocks to be smooth?

Answer 1

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!

Answer 2

When most people think of weathering, they may think of jagged rocks, shaped into that position by waves smashing at its side. There is also smooth weathering. Occasionally you'll find a rock that is completely smooth, which is pretty cool. But how do rocks get weathered smoothly?

A lot of the time when you find a smooth rock, it is because humans have made it smooth so nobody will be hurt by it, but naturally smooth rocks are weathered by wind. Without sand and small rock particles, and etc. the wind does mostly nothing, but with rock particles it can make a huge effect. If you ever see desert formations, they are mostly smooth because of the constant weathering put upon it by the sand and wind teaming up.

Thanks and that is my answer.
