Chapter 4 . ROCKS “The Mixture of Minerals”. Rock – a naturally occurring solid mixture of crystals of one or more minerals. Rock Cycle – the continual process by which new rock forms from old rock material. Rocks are always changing. The Rock Cycle.
ROCKS “The Mixture of Minerals”
Heat and pressure may cause a rock to chemical change into a metamorphic rock.
If the rock gets too hot it will melt which eventually cools to form igneous rocks.
The relationship of heat and pressure:
Gravitational Potential Energy – is the potential energy associated with gravitational forces, as work is required to elevate objects against Earth’s gravity.
You are going to need your notebook for this activity.
In the output section record 10 rolls of the dice. (Write down what the dice said.)
You may never move from a station but continue to roll the dice at that station and write down what the dice said.
Once you have finished return to your seat.
In order to identify rocks scientist break the rocks up into two categories:
Composition and Texture
Your assignment: Create a children’s story, comic strip, or some other creative story about Roger the Rock.
Roger is a rock that has been a part of the rock cycle for millions of years. Your job is to tell Roger’s story. You must describe how Roger was “born” and at least three transitions that occurred during Roger’s life. (For example, changing from igneous to sedimentary, sedimentary to metamorphic, and metamorphic to igneous.)
Your grade will be based on in-class work, the accuracy of your information, creativity, and neatness/effort. This should be a story appropriate for a children’s story (think back to 2nd grade here!), including pictures.
To earn an “A”, you need to include many details-the names of specific rock types, descriptions about what causes the changes to occur, etc.
This project will be due on the day of Chapter 4 Test. These projects will be presented by you and your partner.
Ridge Push – Gravitational force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
