the two theories that attempt to explain earths magnetic field are
Dynamo theory--the theory that is believed by the majority of geologists. it says the rotation of the earth causes the liquid core to move in one overall direction, causing the movement of electrical charges, creating the current making the magnetic field. Rapid-decay theory---is believed by the minority of geologists. it makes assumptions about how the earth was formed to calculate how much electrical current would be generated and how much it would have slowed down. =

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 bats use the earths magnetic fields?
no
Earths magnetic field does not affect what?
Other planets
What gives rise to the Earths magnetic field?
Current flows inside he Earth.
What do scientists think produces earths magnetic field?
Its molten iron core.
What other theories try to explain the current position of earths continents?
Magnetic orientaion
Discuss briefly the 4 theories on the origin of the moon?
I think the unanimus answer is that when the earth collided with another planet(putting it on a tilt) a chunk broke off and got caught in the earths magnetic pull. There are no other theories i know of.
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Is Lanthanum magnetic?
which of the list of rare earths are magnetic
How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Is earths core a source of earths magnetic field?
Yes.
How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
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.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
Switch in direction of earths magnetic north and south poles?
Magnetic Reversal
