Types of Rocks - Page Text Content

BC: Assignment For this assignment the students will be required find 3 picture of 3 different types of rocks from the classification list (25 points) For each picture the student the student must compose a pose which will include a description of the rock, its classification, location of possible place of origin, and how it is formed (50 points) Finally, each student will be required to bring in 1 type of rock (igneous, sedimentary, or metamorphic) to class to present to the class (25 points)

FC: Classification of Rocks by Mr. Martino & Mr. Bousson's 8th Grade Science class

1: In this mixbook you will find different types of rocks. For each rock found, you will know its description, its specified classification, the location where each rock can be found, and how it forms over time. Enjoy!

2: What is a rock? A rock is a naturally occurring solid aggregate of one or more minerals How do we classify them? Rocks are geologically classified according to the fallowing characteristics: 1) Mineral and Chemical Composition 2) Texture of Particles 3) Permeability 4) Particle Size These physical properties are the end result of the rock formation process

3: How are rocks formed? Rocks are formed over a course of time, and can transform from one type into another (Described in Rock Cycle Diagram) The events that take place in the rock cycle produce 3 geological classes of rock: Igneous, Sedimentary, and Metamorphic

4: Igneous Rock Igneous Rock is the first thing produced in the rock cycle and there are over 700 different known types It is formed through the cooling and solidification of magma of lava from the planet Igneous Rocks are divided into 2 main categories -Plutonic or Intrusive Rocks results when magma cools and crystallizes slowly within the Earth's crust --> Ex: Granite -Volcanic or Extrusive Rocks results from magma reaching the surface as lava or fragmental ejecta --> Forms minerals such as Pumice and Basalt

5: Sedimentary Rock Sedimentary Rock is formed by the deposition (adding of sediments) of material at Earth's surface and in bodies of water Sedimentation is a name for the process that causes mineral or organic particles to settle and accumulate Particles that form sedimentary rock by accumulating are called sediments Before being deposited, sediment is formed by weathering and erosion in a source area --> it is then transported to the place of deposition by water, wind, ice, and mass movement of glaciers

6: Metamorphic Rock Metamorphic Rocks form from the transformation of existing rock types, in a process call metamorphism --> Metamorphism: the original rock is subjected to heat (greater than 150-200 degrees Celsius) and pressure (1500 bars) causing chemical and physical change Make up a large part if the Earth's crust and are classified by texture and both chemical and mineral assemblage Ex of Metamorphic Rock --> Sillimanite --> Kyanite --> Staurolite --> Some Garnet

8: This is a marble rock. It is made up of composed of coarse crystals from limestone. It is a metamorphic rock. Marble could be found in areas of uplift and folding at depth, or exposed areas of old mountains. It is formed by the metamorphism of limestone. by: Phil Robertson

9: To the left is a picture of a granite rock. This is part of the Igneous rock category. Granite is a very hard stone. It's hard because it formed as hot liquid stone, and so the molecules inside it are all jumbled up any which way, instead of lying in layers. It is formed when bits of quartz and feldspar are shot out of volcanoes. Granite can generally be found deep beneath the Earth's surface, but can also be found on the surface in places where extensive erosion has taken place. by: Steph Miller

10: Anthracite coal is a metamorphic rock that is a hard natural coal of high luster differing from bituminous coal in containing little volatile matter and in burning very cleanly —called also hard coal. | Anthracite coal is mostly found in northeastern Pennsylvania but can also be found in small amounts in Arkansas and China. It forms during mountain building when compaction and friction are extremely high. by: Steven Austin

11: Sandstone is a type of sedimentary rock. It is made up of sand grains that have been compacted for a long period of time. | Land that used to be covered in sand like in deserts or dry place and places that used to be beaches. It is found most everywhere, India, United States, Europe, England and other places as well. | by: Anthony Long
