The inner core and outer core of the planet are composed primarily of iron and nickel. The outer core is liquid and the inner core is solid. It is thought that the convective motion of the liquid outer core is responsible for generating the main field. Recent studies indicate that the inner core of the Earth may rotate a bit faster than the outer core and it is possible that this rotation may be associated with field reversals.

What does the inner magma in the Earth do?
The inner magama rotates creating earths magnetic field which stops solar wind
Does the Prickly Pear Cactus help the environment?
Every plant on earth helps the environment its man who causes the problems.
What causes one year?
A year is the amount of time that the earth takes to do one complete orbit of the sun. The earth is locked in to an orbit which is dependant on its speed of motion, its mass and its distance from the sun.
Heat from the earth's interior causes convection currents in which layer of earth?
Convection currents in the magma drive plate tectonics.Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere.
What causes diamonds in Africa?
All diamonds are formed deep within the earth's mantle and are erupted to the surface by way of volcanic pipes. Diamonds are found on every continent except Europe and Antarctica. That there are diamonds in Africa is simply part of the earth's composition and geological evolution.
Is it true when magnitic minerals grains in a rock form they become magnetized in the direction parallel to earth existing magnetic field?
true
How is the energy transmitted to earth?
throught the magnitic feilds og earth and the atmoshere
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
What are the lines of force around a magnet?
the imaginary lines around the magnet is a magnitic field and strong
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
How is earth a magnetic field?
The earth's magnetic field is caused by the fact that the earth has a moltern iron core. When moltern iron spins it causes an electric field. This causes an electromagnetic field. Some planets are too large or too small for the iron in their core to be molten.
Where does the convection occur that causes the Earth's magnetic field?
This happens in the earth's core.
The convention that causes earths magnetic field happens in earths?
core
Does phobos have a magnitic feild?
yes
What causes Earth's magnetic field to have the shape it does?
As you might already know, a magnet is the most powerful at it's ends. So what the inner core of the Earth's magnetic field does is that it surround the Earth. Thank you.
Is aluminum magnitic?
No, iron and steel are though.
What causes arnie to be lighter on venus than on earth?
Venus has less mass than earth and therefore a weaker gravity field.
