[Intro]
What’s the hardest rock?
The hardest rock (is not to rock)
It’s a mineral…
(If you’re being literal)
[Verse 1]
Your my kind, Diamond
I love the way you shine
(Oh so fine)
You spin my head round
[Bridge]
What’s the hardest rock?
The hardest rock (is not a rock)
It’s a mineral…
(If you’re being literal)
[Chorus]
They say you’re my best friend
(Again and again)
You’ll stay with me to the end
(And begin again)
[Bridge]
Formed under pressure
(And sure to endure)
[Verse 2]
Diamond, I love you so
I love glimmer
(And how you shimmer)
I love you so (don’t you know? oh oh)
[Bridge]
What’s the hardest rock?
The hardest rock (is not a rock)
It’s a mineral…
(If you’re being literal)
[Chorus]
They say you’re my best friend
(Again and again)
You’ll stay with me to the end
(And begin again)
[Outro]
Formed under pressure
(And sure to endure)
A SCIENCE NOTE
The hardest rock is diamond, which is actually a mineral rather than a rock. Diamond ranks 10 on the Mohs hardness scale, making it the hardest naturally occurring substance.
The main difference between a rock and a mineral is in their composition and structure:
Minerals:
Definition: A mineral is a naturally occurring, inorganic solid substance with a specific chemical composition and a crystal structure.
Characteristics: Minerals are made up of elements or compounds, like quartz (SiO₂), feldspar (KAlSi₃O₈), or diamond (C).
Example: Quartz, calcite, and mica are all minerals.
Rocks:
Definition: A rock is a naturally occurring solid aggregate or mixture of one or more minerals or mineraloids.
Characteristics: Rocks are made up of combinations of minerals, mineraloids (substances that resemble minerals), and sometimes organic material.
Example: Granite (a rock made of quartz, feldspar, and mica), limestone (mostly made of calcite), and basalt (made of minerals like plagioclase and pyroxene).
