Magnetic Reversals (Cool Geology Assignment)

Images and Diagrams

Figure 1:

Diagram of a Magnetic Reversal.

- Displays the flow of the magnetic field in it's current state, then displays the flow of the field durring a reversal. (Image Source: http://www.astrosciences.info/magflips.htm)

Figure 3:

Diagram of Magnetic Striping

Shows how the magnetic striping along the sea floor ir represented symetrically on each side of the ridge, also shows in a smaller pictire where the Mid-Oceanic Ridge can be found. (Image Source: http://www.calstatela.edu/faculty/acolvil/plates/ocean_magnetism.jpg)

Diargam of years and eras the earth was in reversed and mormal polarity

- Futher showing the flow of the Magnetic Field durring a Magnetic Reversal. (Image Source: http://www.windows.ucar.edu/glossary/images/mag_dynamo_progression.gif)

- Diagram above shows the eras in which normal and reversed polarity occured and for how many years it lasted. (Image Source: http://www.calstatela.edu/faculty/acolvil/plates/magnetic_reversals.jpg)

Figure 5:

Magnetite Rock

- Image of Magnetite rock with a magnet on it. This is the type of volcanic rock that records the flow of the Earth's Magentic Field. Commonly found along the ocean floor.

Isn't this sooo cool?
