The Rock Cycle ??



What is the difference between a rock & a mineral?

  • Minerals are solid, inorganic, naturally occurring, and have a fixed crystalline structure made of one or more elements.

  • A rock is a naturally occurring solid mixture of one or more minerals and organic matter.


The value of rocks
The Value of Rocks

  • Rock is an important natural resource.

  • Rocks can be made into:

    • Hammers

    • Arrowheads

    • Spear points

    • Knives

    • Scrapers

    • Buildings

    • Monuments

    • Roads


How do we classify rocks
How do we classify rocks??

You decide!!!

Create a Circle Map in your interactive notebook describing how you would classify these rocks!


How do we classify rocks1
How do we classify rocks??

Rocks are classified by how their Formation, Composition, and Texture.


3 types of rocks that s it
3 Types of Rocks… that’s it??

  • Igneous Rocks

  • Sedimentary Rocks

  • Metamorphic Rocks

    Raise your hand if you recycle: Paper, plastic, aluminum…

    The Earth recycles too!!! One thing it recycles is ROCK!

  • On your desk you should have:

  • Agenda (opened to PRIDE card)

  • Interactive Notebook

  • Pencil/Pen

  • How are weathering and erosion different?

    Weathering is the breakdown of rock into sediment due to the sun, wind, and rain whereas erosion is the movement of sediment from one place to another.

  • What is deposition?

    Deposition is the process in which sediment is laid down.

Igneous rocks
Igneous Rocks

  • Where do Igneous rocks come from??

  • ……VOLCANOES!

  • Temperatures deep within the Earth are hot enough (14000F to 23000F) to melt rock


Igneous rocks1
Igneous Rocks

  • Intrusive igneous rock- Forms when magma cools within the Earth

  • Extrusive igneous rock- Forms when lava cools on Earth’s surface


Textures of igneous rocks
Textures of Igneous Rocks

  • Texture = size of the rock’s mineral crystals

  • Large crystals- slow cooling time

    • Intrusive rocks commonly have large crystals

  • Small/No crystals- fast cooling time

    • Extrusive rocks commonly have small or no crystals


Textures of igneous rocks1
Textures of Igneous Rocks

  • Large Crystals

  • Small/No Crystals


Ship rock
Ship Rock

  • Formed 1km below Earth’s surface

  • It was once intrusive igneous rock

    • It is what’s left behind of magma that once fed a volcano

  • Through weathering and erosion, surface rock has been worn away…

  • …Ship Rock survives because igneous rock is usually harder than other types of rocks


Quick quiz
Quick Quiz

What causes igneous rocks to have different textures?

Bell Work 9/27/13

  • On your desk you should have:

  • Agenda (opened to PRIDE card)

  • Interactive Notebook

  • Pencil/Pen

1. How are igneous rocks with large crystals formed?

2. How are Igneous rocks with small or no crystals formed?


Sedimentary rocks
Sedimentary Rocks

  • Form from sedimentsthat undergo lithification (get compacted and cemented together into rock)

  • Sediments- Can be pieces of rocks, minerals, plants, or animals


Sedimentary rock formation
Sedimentary Rock Formation

  • Rainwater washes away rock particles…

  • Flow downhill to streams and rivers…

  • Eventually these sediments reach the ocean…

  • Settle on the bottom of the ocean…

  • Pressure eventually forces these sediments together…

  • Sedimentary rock is formed!


Organic sedimentary rocks
Organic Sedimentary Rocks

  • Coal-

    • Made up of remains of plants (dead wood, bark, leaves, etc.)

    • Started forming millions of years ago

  • Limestone-

    • Made up of remains of ocean organisms (shells, bones, etc.)

    • Pressure “squishes” these materials together into rock


Limestone towers mono lake
Limestone Towers (Mono Lake)

  • Minerals can dissolve in water …

  • …and then re-form as the water evaporates

  • Often they form underwater and become visible as the water level drops.


Metamorphic rock
Metamorphic Rock

  • Forms when heat or pressure cause older rocks to change into new types of rocks

  • Metamorphism-

    • The process in which existing rock is changed by heat or pressure


  • Metamorphic rock1
    Metamorphic Rock

    • During metamorphism rocks undergo many changes

    • Heat and pressure can break the bonds that join the atoms in minerals… the atoms then join together differently

      • Recrystallization

    • Rocks do not melt during this process!!!


    Textures
    Textures

    • Foliation- An arrangement of minerals in flat or wavy parallel bands

    Foliated Rocks

    • Develop under pressure

    • Minerals flatten out or line up in bands

    Nonfoiated Rocks

    • Develop if rock is made up of only one type of mineral

    • May not be under enough pressure

    Foliated or Nonfoliated??
