Palaeomagnetism is a record of the Earth’s past magnetic field. When lava is erupted at the surface, magnetic minerals, such as iron, in the lava align parallel w...

Therefore, Paleomagnetism showed the changes in magnetic polarity that sea-floor spreading results in. Furthermore, there is evidence of sea-floor spreading through glacial deposits since deposits formed during the Permo-Carboniferous glaciation are found in Australia, Africa, Antarctica, India and South America.

Explain how Paleomagnetism can be used as evidence for Continental Drift? When hot magma rises towards the surface and cools, iron particles, inside the cooling rock, align themselves with the earth's polarity at the time of cooling.

Palaeomagnetism deals with the past magnetic states of the earth. In the 1900's geographers were interested in the mid Atlantic ridge, its on a constructive plate...

Seperate evidence found from paleomagnetism. This expands on Wegener's theory's by explaining how continents could move over a solid earth. 1948 survey of Atlantic ocean floor revealed Mid Atlantic Ridge (MAR). 1000 km wide, heights of up to 2.5 km. volcanic rocks. Similar range found in pacific later, extending over 5000 km.

Crystal size is used to distinguish between intrusive and extrusive igneous rocks. Intrusive rocks such as granite will have coarse crystals whereas extrusive roc...
