  1. ROCK OUT!!! By: Tina Hayes

  2. How Is An Igneous Rock Formed? Igneous rocks are formed in three different areas like where lithospheric plates pull apart at mid-ocean ridges, where plates come together at subduction zones and where continental crust is pushed together, making it thicker and allowing it to heat, and to melt. Also there are three different types of Igneous rocks, Extrusive, Intrusive, and Plutonic. They each have a texture too. Extrusive rock cools quickly (from seconds to months) and have invisible or very diminutive grains, Intrusive rock cools slower (over thousands of years) and have small to medium sized grains, and Plutonic rock cools the slowest out of all three(over millions of years. But they all cool the same way; they all start out as magma and when that lava freezes (over time) it forms one out of the three Igneous rock. Some Igneous rocks can comprise of diminutive grains and some can have fairly large grains inside them. There are three different types of Igneous rock, Extrusive, Intrusive, and Plutonic. This Intrusive Igneous rock cooled over thousands of years to reach it’s final form. Igneous rock forms when it’s base is heated and then cooled over time.

  3. How Is A Sedimentary Rock Formed? Sedimentary rocks are formed by water and Sediments. The rocks usually form underwater because all of the sediment on the ocean crushes together because of all the water pressure and that’s what creates the sedimentary rocks. Sedimentary rocks are formed by water and sediments combined. A diagram of how Sedimentary rocks are formed. Water pressure forms Sedimentary rocks under the ocean crust.

  4. How Is A Metamorphic Rock Formed? Metamorphic rocks are formed when the weather is at least 150 ۫۫۫۫ Celsius to 200 ۫ Celsius. They form deep under the earth’s surface by pressure and minerals. Every rock is different, whether it’s the name, the texture, the shape, the name, they’re all different. Every Metamorphic rock is different in many ways from their name to their texture. The weather has to be at least 150° Celsius to 200° Celsius for a Metamorphic rock to form. Some Metamorphic rocks have a pattern, like this one here.

  5. Rock #1 Name of Rock: Scoria Classification: Igneous Description of Rock: A dark colored, vesicular Extrusive Igneous rock, vesicles in the rock are a result of gas being trapped in the melt during solidification period. Where found: In the deepening hills of my backyard. Description of location: In the far right hand corner of the flower patch half covered in snow along the fence post area. Date found: January 24, 2011

  6. Rock #2 Name of Rock: Iron Ore Classification: Metamorphic Description of Rock: A chemical rock that forms when iron and oxygen combine in solution, it also contains one of the most common mineral in a rock, Hematite. Where found: Right around the bend of my porch step. Description of location: Nearly at the end of my backyard but not quite. Date found: January , 2011

  7. Rock #3 Name of rock: Schist Classification: Metamorphic Description of Rock: A rock with developed foliation, and it also contains some kinds of Mica. Where found: In my one of my mother’s flower beds.. Description of location: Close to the street curb laying in a pile of mulch, grass, and snow. Date found: January 18, 2011

  8. Rock #4 Name of Rock: Marble Classification: Metamorphic Description of Rock: A non-foliated rock produced from the metamorphism of Limestone composed primarily of calcium carbonate. Where found: About a ¼ of an inch away from my fence. Description of location: My rock was located incredibly close to the fence post near the end of my lawn. Date found: January 18, 2011

  9. Rock #5 Name of Rock: Granite Classification: Igneous Description of Rock: A Corse grained Intrusive Igneous rock that contains pieces of Quartz, and Feldspar minerals. Where found: In a hole under one of the bushes in my backyard. Description of location: near to the bottom of the hole but a few other Granite rocks were sitting under it. Date found: January 18, 2011

  10. Rock #6 Name of Rock: Breccia Classification: Sedimentary Description of Rock: A clastic rock composed of angular fragments, often the spaces between the fragments are filled with small particles or mineral cement. Where found: In the middle of my front lawn, probably thrown into our lawn by a car or bicyclist. Description of location: In-between tall blades of icy, cold grass and covered in snow. Date found: January 26, 2011 Breccia rock contains angular fragments ranging in sizes of massive to diminutive. In-between the fragments often contain small particles or mineral cement. These intriguing Sedimentary rocks can be found in any color too.

  11. Rock #7 Name of Rock: Slate Classification: Metamorphic Description of Rock: A foliated rock formed from the metamorphism of Shale, a very low grade rock, you can find Shale often in many rocks. Where found: On my way home from a park in the summer. Description of location: Shining in the grass on a humid warm summer day glimmering in the sun with a perfect angle for seeing, as if it wanted me to pick it up and keep it. Date found: August 27, 2010 Often times Slate is a flattened rock and has a blackish brownish color to it. Slate can be used in many ways like this Slate house wall. Slate is a foliated Metamorphic rock that is formed by Shale.

  12. Rock 8 Name of Rock: Peridotite Classification: Igneous Description of Rock: Peridotite is a corse grained rock made almost entirely of Divine, this specific rock may also contain bits of Amphibole, Feldspar, Quartz, and Pyroxene. Where found: I was walking around a creek with my friend and found a unique, glimmering rock glaring at me as though begging me to pick it up. Description of location: Near my neighborhood is a creek and in the summer you can catch crawdads and locate shells and as I strolled through the water I stepped on the ferocious rock stabbing my foot in pain I snatched it up and screamed! Date found: June 12, 2010 This intriguing corse grained rock can be found in colors such as black and brown. Peridotite can contain Amphibole, Feldspar, Quartz, and Pyroxene. Peridotite specifically is made almost entirely out of Divine.

  13. Rock #9 Name of Rock: Phylite Classification: Metamorphic Description of Rock: A foliated rock made entirely out of fine grained Mica. Where found: I traveled to Disney World and they had a huge garden with many rocks and this specific one was one of a kind. Description of location: In my favorite flower bed in the whole Epcot park lay a brilliant rock called Phylite I had to keep it so I took it from the bed of magnificent flowers and put it in my pocket for a rainy day. Date found: October 14, 2010 Some colors you can find Phylite in are red, silver, and gray. An example of a red Phylite rock is this one above. Fine grained Mica is what this rock is made out of.

  14. Rock 10 Name of Rock: Sandstone Classification: Sedimentary Description of Rock: A clastic rock made up of sand-size, weathering debris- this rock can accumulate on beaches, deserts, flood plains, and deltas. Where found: Interesting story, I found this rock under my sister’s bed trying to find her slippers for her, I thought WOW this would be an awesome rock to put in my Rock Collection. Description of location: Even weirder I found her slippers with this rock in them so I never told her I found her special rock and kept it as my own and surprisingly she never found out, I wonder if she misses it? Date found: February 5, 2011 DID YOU KNOW? The Capitol of Colorado was going to be made entirely out of Sandstone but they decided not to because it wasn’t strong enough. These rocks can accumulate on Beaches, deserts, flood plains, and deltas. This rock is made out of sand-size, and weathering debris.

  15. Rock #11 Name of Rock: Tuff Classification: Igneous Description of Rock: Tuff is composed of materials ejected from volcanoes, the materials fell to the Earth and lithified into a rock, Tuff also contains volcano ash and particles such as Cinder. Where found: Dripping wet in the rain located in my backyard. Description of location: After a down pour in the summer I decided to go outside because there is always a rainbow, but instead I noticed this rock gleaming right in my face after all the water we received. Date found: June 19, 2007 Tuff also contains volcano ash, and particles such as Cinder. This rock was formed when certain materials fell to the Earth and lithified. Materials such as volcanic ash make up this significant rock.

  16. Rock #12 Name of Rock: Diorite Classification: Igneous Description of Rock: A corse grained Intrusive Igneous rock that contains a mixture of Feldspar, Pyroxene, Hornblade, and Quartz. Where found: In the Ohio River, with my five cousins. Description of location: My cousins (before they moved) lived in Cincinnati, Ohio and every time we visited them we would always do something really fun and two years ago in the summer we went to the Ohio River! Near the Ohio River is a play area with trees and lots and lots of rocks and because I was barefoot and stepped on one of the sharpest rocks there and when I picked up this rock I had to keep it so along with all my seashells I took a rock home to Colorado too. Date found: July 17, 2009 As you can see Diorite is much like Peridotite in color and the mixture that forms it. Diorite is a very corse grained rock with a mixture of many other rocks and minerals. This Plutonic Igneous rock cools over millions of years before it reaches its final shape and form.
