1. How are igneous rocks formed?2. What are the two TYPE of igneous and provide THREE examples of each?

3. How do Metamorphic rocks form?4. What are the TWO types of metamorphic rocks and provide TWO examples of

each.

5. How does the cooling rate impact the size of crystal in a rock?

6. Coal is _______________, meaning made up of living material.7. Which mineral has a hardness of 7?8. ________________ is the way a mineral reflects light. List the FOUR types and

provide an example of each.

9. Which minerals is the ores of iron, bauxite and lead?

From magma and lava

Intrusive- formed from magma inside the earth Ex: granite, gabbro, basalt

Extrusive- formed from lava or volcanoes Ex: obsidian, scoria, pumiceFrom heat and pressure

Foliated- has layers EX: slate, schist, gneiss

Non-foliate: has NO layers EX: marble, quartzite

Cools Quickly (like volcanic) no crystals, cools slowly large crystals( Like granite)organic

LusterQuartz

Glassy= quartz, halite Pearly, Waxy = muscovite mica, gypsumDull/earthy= corundum, kaolinite Metallic= graphite, galena

Hematite= iron Galena= lead Bauxite=aluminum

Do Now-Sedimentary Rocks- PURPLE crossword on desk1. List and Describe the THREE types of Sedimentary Rocks. Then, provide an

example for each TYPE of sedimentary rocks.A. Clastic-

B. Chemical-

C. Organic-

Made up of piece of rocks that are cemented together.Example: sandstone or conglomerate

Made from chemical reaction of water and a given mineralexample: Limestone and geodes

Made up of living material

Example: coal or limestone

NAME THE TYPE THEN THE NAME OF THESE SEDIMENATRY ROCKS:

Organic

ShaleGeode

Chemical

Conglomerate

Clastic

1.What is the difference between fracture and cleavage?

List 3 minerals with Cleavage:

Do Now:

List 3 minerals with Fracture:

1. 1.2. 2.3. 3.

2. What is the difference between rocks and mineral?

Fracture has NO SPECIFIC shape in the way the mineral naturally breaksCleavage does have some kind of specific shape in the way it breaks

Halite- Cubic

Mica- This sheets

SulfurCalcite- Rhombic

Graphite

Fluorite

Minerals have specific chemical composition and chemical structureRocks are made up of different minerals
