Magnetic . This has been charted and monitored since, I would imagine the times of such pioneer physicists as Newton and Halley. Exactly how and why these fluxions ( as Newton called- them, later applying the term to Calculus) occur is not precisely understood. Nature holds many arcane secrets.

∙ 13y agoThe Earth's magnetic field reverses from time to time, the last reversal occurring a little less than 800,000 years ago. Each reversal is preceded by a weakening of the field followed by a quick strengthening as the field takes up it's new orientation.

What happens to earth's magnetic field over time?
It weakens and eventually disappears
What are affects of earth magnetic field?
effects of earth's magnetic field:-The sun emits huge amount of solid charged particles every time(called solar wind). if these particles are allowed to enter our earth, then there would be no chance of existence of life as this horrible effect of the solar wind would scrape away the atmosphere of our earth. but this magnetic field of our earth repels all these solid particles from the sun. by K.

How long do epochs last?
Magnetic epochs last a long period of time, geologically. It is when the earth's magnetic field is the same polarity.

What does earths mass create?
Earth's mass creates a gravitational field, which is the effect of the warping of space time any massive body creates.
What is Earth's field that reverses from time to time?
The Earth's Magnetic field.
What earth field reverses from time to time?
magnetic field
What is earths field that reverses from time to time?
The Earth's Magnetic field.
The magnetic particles in seafloor ridges are aligned differently in a repeating pattern How does this provide evidence for tectonic movement Why does it provide evidence?
Earth's magnetic field reverses over time; the changes show that seafloor has taken place over time.
A long time ago people believed that the - blank - was the center of the universe?
Earth
Why does the earths magnetic field change over time?
The Earth's magnetic field changes over time because that is the way that God makes it.
The BLANK is the most reliable source of energy for life on earth?
Radiation from the Sun-it's been going for a long time!
How can the magnetic field of the Earth be sued to estimate the age of rocks found in the Earth?
By knowing the precise orientation of the rocks magnetic field, you can compare its magnetic field direction to the known direction of the magnetic field over time since the "north pole" wanders over time. The rock locked in its magnetic field when it cooled from magma.
What is the meaning of pole when describing earth?
Earth has two pairs of poles, the geographic north and south poles and the magnetic north and south poles. The geographic poles are the two places where Earth's rotational axis, the imaginary line that represents the center of Earth's rotation, intersects the surface of the earth. The magnetic poles are where Earth's magnetic field diverges/converges, just like the poles of a bar magnet, except that Earth's north magnetic pole is comparable to the south pole of a bar magnet, and Earth's south pole is comparable to the north pole of a bar magnet. The locations of the geographic poles never change, but the magnetic poles wander around from time to time. In fact when studying the floor of the Atlantic Ocean for the first time scientists found evidence that the polarity of Earth's magnetic field completely reverses every few hundred millennia (the north and south magnetic poles switch places).
What happens to earth's magnetic field over time?
It weakens and eventually disappears
Describe how the polarity of earth's magnetic field is recorded in the sea floor?
The position of Earth's magnetic field changes over geologic time, pole is located near Earth's North Pole, a condition called normal polarity.
What do lava samples tell scientists about what has happened to the earth magnetic field over geologic time?
The magnetic field periodically changes its orientation.
