How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
Where is Earths magnetic reversals recorded?
in plate tectonics
The patterns of iron particles found in sea floor rocks result from what?
The earths magnetic polarity at the time of rock formation.
How is the orientation of earths magnetism recorded in rocks on the?
Earth's magnetic orientation is locked into the rock when the rock cools
When new basalt forms along mid-ocean ridges it become magnetized?
accorsing to the earths magnetic field

Will the polarity of the earths magnetic field change in 2012?
There is no reason to believe that the Earth's magnetic field will change any time soon... or, for that matter, that anything extraordinary is going to happen in 2012.
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.

Explain how the reversal of earths magnetic poles can be produce a calendar for part of earths history?
In rock formed when the sea floor is being built, such as at the mid-Atlantic ridge, the minerals preserve the magnetic polarity. Since the flipping of the poles is fairly regular, the count of the bands can give a time.
Where is earths magnetic North Pole?
compasses point to it. its at the north pole in the arcticNo It's not, the Magnetic North Pole is at this moment just off Ellesmere Island heading towards Russia at a rate of 40 miles (60 km) per year.AnswerIt depends what you mean by 'magnetic north pole'. If you mean the location, called 'Magnetic North' (arctic), then its polarity is south. If, by 'magnetic north pole', you mean its magnetic polarity, then it's located at Magnetic South (antarctic).
What happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.
