Geology Part 3

Today I will write about a few different types of plains such as lake plains, glacial plains, and lava plains. Lake plains form when water brings and drops sediments into a lake.  When that lake dries, it becomes a plain.  Sometimes glaciers make the ground around them flat by eroding the rock to a flat surface, carving…

Geology, Part 2

These are the three categories of rocks and minerals: Igneous, Sedimentary, and Metamorphic.  This is what I’ve learned about them. Igneous Igneous rocks are rocks that were melted and then it hardened.  The word igneous comes from the latin word ignis meaning “fire”.  A lot of the earth’s crust is made up of feldspar, mica,…

Geology part 1

In August we are going to Montana with Mr. Pat (The Rock Guy).  Mr. Pat has suggested a book to me to study before we go; it’s name is The Geology Book by Dr. John D. Morris.  This is some of my notes of what I learned. Chapter 1: Our solar system is made up of 9 planets…

What are the most common crystal habits?

Now I am going to tell you about in what shapes the crystals form, which is called their habit.  The names of the habits are, Acicular, Bladed, Dendritic, Equant, Prismatic, Striated, and Tabular.  You may have never have herd about these, but don’t worry I am going to tell you what they all mean.  Let’s start with the first one Acicular, which…

Beryl

I picked Beryl to study next because the one I owned was from India which we visited last year.  I didn’t get it in India but it was in my Mining and Geology of the Old West Kit.  Then I realized it was the one in the Bible in the same row as Onyx and…

A Purpose for Scratching Minerals

Did you know that some minerals you can scratch with your fingernail? Frederick Mohs invented the scale of 1 – 10 hardness.  All minerals are now fit into this scale of hardness.  Higher numbers scratch any number lower than that number.  For example, 7’s will scratch 6’s, but 6’s will not scratch 7’s.  Finding out…
