Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
What else can I help you with?
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
Why do scientists believethat the inner core is the source of earth's magnetic field?
The core is a dense chunck of metal that influence the earths magnetic field.
How do birds learn how to migrate?
Its an internal instinct, and some scientists say it has something to do with the Earths magnetic pull.
How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
What do scientists think produces earths magnetic field?
Scientists think that Earth's magnetic field is generated by the movement of molten iron and nickel in the outer core of the planet. This motion creates electric currents, which in turn generate the magnetic field that surrounds the Earth.
What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
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.
Why do scientists think the earths core contains iron?
Scientists think the Earth's core contains iron because of the planet's magnetic field. Iron is a magnetic material, and the Earth's magnetic field is generated by the movement of molten iron in the outer core. Additionally, seismic waves and the density of the Earth indicate a high concentration of iron in the core.
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
Why do you think scientists study earths interior?
Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.
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.
