1. For those about to Rock
We salute you!

2. review Use the iPads to research and add to your
Last time we organized rocks according to shapes, size, colors, ect.
We then reorganized them according to 3 categories, which are:
Sedimentary
Metamorphic
Igneous
Use the iPads to research and add to your
notes on the 3 different rock types.
Leave some space for additional notes.

3. What type of rocks are these?

4. Sedimentary rocks Clastic Chemical Organic
These rocks are formed by the accumulation of sediments. Pressure is the primary source of formation, not heat.
There are 3 different types of sedimentary rocks:
Clastic
Chemical
Organic

5. Sedimentary
Breccia is a clastic sedimentary rock that is composed of large angular fragments. The spaces between the large fragments can be filled with a matrix of smaller particles or a mineral cement which binds the rock together. 
Other clastic sedimentary rocks include conglomerates, sandstone, siltstone and shale. These are formed by mechanical weathering.

6. Sedimentary
This is Chert. It’s a sedimentary rock formed by chemical composition. Early people took advantage of how chert breaks and used it to fashion cutting tools and weapons.
Other chemical sedimentary rocks include rock salt, iron ore, flint, dolomites and some limestone.

7. Sedimentary
This is coal. It’s an organic sedimentary rock formed mainly by plant debris which accumulates in a swamp environment. Coal is combustible and often used as a fuel source.
Other organic sedimentary rocks include some dolomites and some limestones.

11. Metamorphic rocks Foliated Non-foliated
Metamorphic rocks have been modified by heat, pressure, and chemical processes, usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture, and chemical composition of the rocks.
There are two basic types of metamorphic rocks.
Foliated
Non-foliated

12. metamorphic
This is a Gneiss rock! It’s foliated which means it has a layered or banded appearance that is produced by exposure to heat and directed pressure.
Other foliated rocks include phyllite, schist and slate.

13. metamorphic
This is a non-foliated rock. This specific type is called a hornfels. It does not have a layered or banded appearance. They are produced by contact metamorphism. That means it was "baked" while near a heat source such as a magma chamber.
Other non-foliated rocks include marble, quartzite and novaculite.

17. Igneous rocks Intrusive Extrusive
Igneous rocks are formed by the solidification of molten rock material.
There are two major types:
Intrusive
Extrusive

18. igneous
Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. This particular rocks is diorite.
Other examples of intrusive igneous rocks are gabbro, granite, pegmatite and peridotite.

19. igneous
Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass like this particular example of obsidian.
Other examples of extrusive igneous rocks are andesite, basalt, pumice, rhyolite, scoria and tuff.
