What else can I help you with?
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.
What magnetic qualities does earth process?
Electric currents circulate in the interior of the Earth, and these create an magnetic field, with a north pole and a south pole. But not necessarily aligned with the geographic (spin) poles. If a rock which contains ferric particles is cooling, then those ferric domains will assume the direction of the Earth's magnetic field at the time the parent rock passed through that minerals Curie point. It will contain some 'fossil' magnetism.
Of True North and Magnetic North and Compass North which way is really up?
True North is the real North, following along the lines of longitude which converge at the North Pole, the farthest geographically North point on the planet, and the rotational axis of the planet. Magnetic North and Compass North are both the same thing, with the compass pointing along Magnetic North. Magnetic North however, is not the real North. If you were to follow your compass as far North as it could point, you would end up on the Prince of Wales Island in the Northwest Territories of Canada, over 1,500 miles away from the North Pole. Magnetic North can be adjusted to True North on your compass by knowing the local magnetic variation of your area and adding/subtracting accordingly. A third North is Grid North, which follows the Grid Lines on a standard map. At the South Pole, every direction is True North, so Grid North is used instead and can be found by following the Prime Meridian northwards. Hope that helps.
How did georgia O'keeffe's style change over time?
Georgia changed.....
Is the earth's magnetic field always the same?
The earth's magnetic field is present because of the molten iron in its core. Always a little change keeps on occurring in the earth's magnetic field. Although the change is very little with respect to time,but it is considered one of the major factors for the end of this world.
Reasons for Earth magnetic north poles being mapped and why they need to be kept up to date is?
There are no "magnetic north poles", only one. (There is also a magnetic south pole.)The reason is that the magnetic poles change over time.
What is it called when rocks are different because Earths magnetic poles change places?
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
True or false the magnetic poles are not located exactly at the geographic poles?
True. The magnetic poles move constantly.
Are earths magnetic poles located on its axis?
No, Earth's magnetic poles are not located exactly on its geographical poles. The magnetic poles are located slightly off-axis and can shift over time due to changes in the Earth's magnetic field.
How are positions in geographic compared to magnetic poles?
Geographic poles refer to the Earth's axis points where it meets the surface (North and South Poles), while magnetic poles refer to points where the Earth's magnetic field is the strongest. These poles do not align exactly; the geographic poles are fixed, while the magnetic poles can shift position over time due to changes in the Earth's magnetic field.
WILL The exact location where a compass points will ever change?
No, the exact location where a compass points (magnetic north) does not change. However, the magnetic poles themselves can shift over time due to changes in the Earth's magnetic field.
How have switches in the location of earths magnetic poles been determined?
Magnetism leaves particles in molten metals lined up with north and south poles (magnetic poles, not the Earth's poles). Over time different layers of rock show that the N-S and S-N poles have switched, with S pointing in one direction and S pointing in a different direction depending on the age of the rock.
Why do the magnetic poles move around?
The Earth's magnetic poles are not fixed and can move due to changes in the planet's core. This movement is known as geomagnetic secular variation, which is the continuous change in the Earth's magnetic field over time. It is believed to be caused by the fluid motion of molten iron in the outer core of the Earth.
Is it true earth magnetic poles are located on its axis?
No, Earth's magnetic poles are not located on its geographical axis. The magnetic poles are actually offset from the geographic poles, with the magnetic north pole currently located in the Arctic region of Canada and drifting over time.
Is true about magnetic poleWhich of the following is true about magnetic poleWhich of the following is true about magnetic poleWhich of the following is true about magnetic poleWhich of the follow?
Magnetic poles refer to the regions on a magnet where the magnetic force is strongest, typically designated as the north and south poles. Opposite poles attract each other, while like poles repel. Earth's magnetic field also has a magnetic north and south pole, which are not aligned perfectly with the geographic poles. Additionally, the magnetic poles can shift over time due to changes in the Earth's molten outer core.
Which location is the magnetic field the strongest?
A magnetic field is generally strongest (most concentrated) at a pole. Note that, while familiar magnets have two poles, it is also possible for a magnet to have more than two. Whether a magnet could have only pole is controversial. The Earth's magnetic field is strongest at the north and south magnetic poles, which are near the north and south geographic poles. The magnetic poles move over time and are generally not located precisely at the geographic poles.
What has caused the zebra pattern in the rocks of the ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.
