π What are Smooth Rocks?
Smooth rocks are rocks that feel soft and even when you touch them. Imagine petting a cat β that's kind of how a smooth rock feels! These rocks have been worn down by water, wind, or other rocks rubbing against them for a long, long time.
- π Smooth rocks are often found near rivers, lakes, or oceans because water helps to polish them.
- ποΈ Think of pebbles on a beach β those are great examples of smooth rocks!
- π± Over time, smaller pieces of the rock break off, leaving a smoother surface.
ποΈ What are Rough Rocks?
Rough rocks feel bumpy or uneven when you touch them. Imagine touching sandpaper β that's a bit like a rough rock! These rocks haven't been worn down as much, so they still have sharp edges and pointy bits.
- βοΈ Rough rocks might be found in mountains or deserts where they haven't been exposed to much water.
- π§± Think of a big, jagged rock you might see on a hiking trail β that's likely a rough rock.
- π₯ The bumps and edges are often the result of the rock breaking apart or being formed quickly.
