Rocks & Minerals

What is the difference between a rock and a mineral?  What do igneous, metamorphic and sedimentary mean?  What are rocks and minerals used for?  It’s all in this honour!

You’ll learn about Mohs scale of hardness.  How hard your fingernails are compared to talc and diamonds.  There’s more — cleavage, specific gravity, lustre, colour, texture and crystals.

Look up Bible references for rocks and minerals, especially the foundations of the New Jerusalem in heaven. Of course, there’s your own collection of rocks and minerals to admire.
