Slide 1: Types of Rocks S. B. Zapatero, MAT Science
Science Teacher Good Morning!!! : Good Morning!!! Slide 3: Rock My Soul
Rock my soul in the
bosom of Abraham (2x)
Oh – oh – oh rock my soul
(Repeat 3x) Slide 4: ROCKS Slide 5: Rocks
The basic building blocks of the lithosphere.
Formed and transported by natural processes on earth.
Science that deals with the study of formation, composition and classification of rocks. Slide 6: Rock divisions -three major families based on how they formed: igneous, sedimentary, and metamorphic.
Each group contains a collection of rock types.
They differ from each other according to the size, shape, and arrangement of mineral grains.
3 types of rocks=3 divisions. (igneous, sedimentary, and metamorphic) The Rock Divisions Slide 7: Igneous rock forms when magma cools and hardened.
Magma - hot liquid made of melted minerals. When magma pours onto the earth’s surface it is called lava. The minerals can form crystals when they cool.
Igneous rock can form underground, where the magma cools slowly. Or, they form above ground, where the magma cools quickly. Smaller crystals may formed.
The crystals grow together and form one igneous rocks. Igneous Rocks "Fire Rock" 2 Types of Igneous Rocks : 2 Types of Igneous Rocks INTRUSIVE IGNEOUS ROCKS
– formed by magma that cools BENEATH Earth’s surface.
EXTUSIVE IGNEOUS ROCKS
– formed by LAVA ON Earth’s surface. Igneous Rocks: : Igneous Rocks: Slide 10: Sedimentary rocks formed from particles deposited by water and wind
If you have ever walked along a beach (which I am sure you have) you may have noticed tiny sand grains, mud, and pebbles.
These are some sediments that eventually form into sedimentary rocks
Sedimentary Rocks can be form in 4 ways by:
Cementation Sedimentary Rocks Lithification : Lithification The process by which sediment becomes sedimentary rock
1st step : erosion
2nd step : deposition
3rd step : compaction
4th step : cementation Slide 12: Erosion occurs when running water or wind loosens and carry away the fragments of rock. Slide 13: Deposition is the process by which sediment settles out of the water or wind carrying it. Slide 14: Compaction - process that presses sediments together. Slide 15: Cementation - process in which dissolved minerals crystallize and glue particles of sediment together. Sedimentary Rocks: : Sedimentary Rocks: Slide 17: Metamorphic rocks - they have "morphed" into another kind of rock.
They were once igneous or sedimentary rocks.
Heat Metamorphic Rocks Slide 18: Heat Pressure Metamorphic Rocks Metamorphic Rock Pictures : Metamorphic Rock Pictures Granite, Gneiss, Shale, Slate, Sandstone, and Quartzite are good examples of metamorphic rocks. Enrichment Activity : Outside activity : Enrichment Activity : Outside activity Direction:
Each group will collect the 10 different stones. Label the stones with 1 to 10.
Use hand lens to determine the texture.
Classify the rocks
Determine the features given on the data sheet for each rock sample.
Based on your observation, identify the types of rocks it belongs. Conclusion : Conclusion What did you find out?

Answer the following Questions:
What is the definition of rock from the video clip?
What do the rocks support?
What are the uses of rocks from the video clip?
Why geologists study rocks? Answers: : Answers: Rock is basic unit that makes up our solid earth.
It supports everything from the grounds we walk on, the oceans, the deserts and the mountains.
Rocks cover our roads, support our buildings and decorate our lives.
Geologist study rocks in search of valuable clues about the history of the earth because they hold information about them past environment and the events they formed them Slide 25: ROCKS Igneous
Rocks Magma Sediments Heat & Pressure Slide 26: In a ½ sheet of paper, write your understanding from the biblical passage taken from 1 Peter 2:5
"…The stone which the builders rejected as worthless turned out to be the most important of all."
