1. It’s Lego Time link

2. Why were the lego structures different?
They have a different arrangement of the same pieces.

3. The internal arrangement of atoms
Why are some minerals harder than others?

4. MOST ABUNDANT ELEMENTS IN MINERALS
***See Earth Science Reference Tables***

5. The Silicates Mineral Notes
The Chemical composition of the Earth’s Crust (page 1 of ESRT’s) is mostly made of oxygen and silicon
** Minerals composed of silicon and oxygen are abundant (lots of them)**

6. The Silica Tetrahedron is:
the building unit for all silicate minerals

8. Consists of:
1 silicon atom surrounded by
4 oxygen atoms

12. Quartz
Olivine
Hornblende
Feldspar
Augite (pyroxene)
Biotite Mica

13. Muscovite Mica
Chlorite
Kaoline
Garnet

15. How do you know if it is a Silicate?
It’s easy,
Just look for silicon and oxygen

16. A diamond and graphite are not silicates, however they are excellent examples of how minerals can have the same chemical composition (Carbon) but different physical properties because of their crystal structure
