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. =
What else can I help you with?
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 the Earths magnetic field at its strongest?
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.
Is a compass affected by the earths magnetic field?
Yes, a compass works by aligning itself with the Earth's magnetic field to determine direction. The needle in a compass is magnetized and will point towards the Earth's magnetic north pole.
Earths magnetic field does not affect what?
Earth's magnetic field does not affect light or sound. It primarily interacts with charged particles such as electrons and protons in Earth's atmosphere and in space.
What forms when earths magnetic field changes direction?
When Earth's magnetic field changes direction, it results in a phenomenon known as geomagnetic reversal or magnetic flip. This process involves the magnetic north and south poles switching positions. These reversals have occurred throughout Earth's history and have been recorded in the rock record.
What other theories try to explain the current position of earths continents?
Magnetic orientaion
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.
Is earths core a source of earths magnetic field?
Yes.
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.
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
What is the magnetic field called?
It is Earths' "Magnetosphere".
What happens in earths interior to produce earths magnetic?
The movements in the liquid inner core.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
What is theories of earths creation?
One of it is the Big Bang Theory.
What is it called when earths magnetic poles change poles?
This is known as magnetic reversal when earth's magnetic poles change places.
What happens in earths interior produce earths magnetic field?
The movements in the liquid inner core.
