We learnt there are soil layers.
What does the word sediment mean?
We put a layer of dirt in a jar and then filled it up with water and shook it up.
Then we watched to see what happened next.
If you look carefully you can see the different layers that have formed in the soil.
Why do you think that happened?
That looked so cool.
ReplyDeleteI didn't know there was topsoil and subsoil.
I wonder how long it will take to break bedrock.
