How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
The patterns of iron particles found in sea floor rocks result from what?
The earths magnetic polarity at the time of rock formation.
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
When new basalt forms along mid-ocean ridges it become magnetized?
accorsing to the earths magnetic field
Is Lanthanum magnetic?

Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
About how long ago was the last time earths magnetic field reversed?
About 41,000 years ago.
The patterns of iron particles found in sea floor rocks result from what?
The earths magnetic polarity at the time of rock formation.
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.
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
The alignment of iron-bearing minerals in rocks when they formed reflections the fact that earths has reversed itself several times in its past?
magnetic field .
When new basalt forms along mid-ocean ridges it become magnetized?
accorsing to the earths 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.
Do earths magnetic poles stay where they are?
No, they move slowly. The North Magnetic Pole, for example, is currently drifting a little west of north at about 40 km/year.
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).
