Homework+Due+Tues+3rd+September

Use the Following sites to answer these questions

1) Explain how the alignment of magnetic fields of minerals in cooling igneous rocks provides an indication of the rocks’ position relative to the magnetic poles. 2) Explain how the palaeomagnetic time scale provides evidence for sea floor spreading. 3) Explain the significance of the discovery of magnetic field reversals on the development of a time scale
 * Beyond Discovery[|Magnetic Clues]
 * **[|Anomalies hint at magnetic pole flip]** - a short article from New Scientist, April 2002
 * **[|Magnetic stripes and isotopic clocks]** - from This Dynamic Earth, United States Geological Survey
 * **[|Plate tectonics and sea floor spreading]- Great tutorial that explains the theory its evidence and its relevance**

[|Developing the theory of continental drift] This is a good site that explains evidence for the theory of plate tectonics
 * Other good resources**
 * [|Plate Tectonics: The Evidence]** - tutorial from Geology Rocks, University of Edinburgh
