Hi, I am a ninth grade student in the Schuylerville School District in New York. My Earth Science teacher has recently presented us with a question, and I was wondering if you could help. He asked if an icicle is a mineral, in its natural form) and all minerals are rocks, then shouldn't icicles technically be part of the lithosphere?
Why or why not is this?
I would really appreciate it if you responded within a few days.


An icicle is solid, being the solid form of water. However, water is not a mineral. Therefore an icicle is not a rock.
