Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] JOAN CARTAN-HANSEN, HOST: Have you ever thought about the difference between a rock and a stone?
This is a case where size matters.
First, you have to know what a rock is.
A rock is a natural piece of the earth made up of minerals and other non-living materials.
Rocks can be as vast as mountains or as large as boulders.
A rock is generally in its original shape as presented by nature.
It's rougher and could be jagged or layered.
A stone is not a scientific term- unless you are talking about stones as an old form of measurement of weight.
But that's a topic for another video.
So, never mind.
A stone is small, loose fragment of a rock.
It is a product of weathering, those forces in nature, like erosion, that break rocks apart.
Stones are more rounded and usually have a smoother texture.
Some stones are actually polished by people to be used in decoration.
Some small, like a diamond or some larger like the polished marble used in a sculpture.
Whether it's a rock or a stone, both come from the earth.
