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.
How would you use the Earth's magnetic field to tell you where on Earth you are?
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
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.
How will magnetic minerals align in a rock if earth has no magnetic field?
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
Earth's magnetic field is believed to be generated from what region?
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
How does magnetic field benefit the people on earth?
The biggest benefit is that it generates the magnetosphere, which helps deflect charged particles from the Sun away from the Earth's surface.
What is the importance of the each magnetic field?
The single biggest benefit to the Earth's magnetic field is that it shields the Earth's surface from harmful radiation.
What is one benefit of using a bar magnet as a model of earth's magnetic field?
HHSHHS
What do magnetic anomalies indicate about the Earth?
Magnetic anomalies indicate variations in the Earth's magnetic field strength or direction. These anomalies can provide information about the geological structure of the Earth's crust and are used in studies of plate tectonics and geophysical exploration.
What is magnetic orientation of rock?
Magnetic orientation of rock refers to the alignment of magnetic minerals within the rock with the Earth's magnetic field at the time of formation. This alignment can provide information about the past magnetic field of the Earth and help in determining the rock's age and geological history.
What are earths alternating magnetic bands called?
Earth's alternating magnetic bands are called magnetic reversals or geomagnetic reversals. These reversals are periods in Earth's history where the magnetic field flips, with the north and south magnetic poles reversing positions. They can be detected in the rock record and provide valuable information about Earth's geological history.
Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
What is the function of the earth induction compass?
It is a device for determining aircraft direction using the magnetic field of the earth. See link to Earth inductor compass
Why do earth magnetic pole reversals provide for plate tectonics?
Rocks lock in their magnetism when they cool.
Does Jupiter's magnetic shield provide more solar radiation protection to us than the Earth's one?
No. Jupiter's magnetic field provides a lot of protection to Jupiter but has absolutely no effect on Earth.
What does the magnetic dip preserved in a rock indicate?
The magnetic dip preserved in a rock indicates the orientation of the Earth's magnetic field at the time the rock was formed. This information can be used to determine the past position of the rock relative to the magnetic poles and can provide insights into the Earth's changing magnetic field over time.
What evidence shows that earth's magnetic field changes?
One piece of evidence is the study of ancient rocks that show reversals in magnetic orientation. Another evidence comes from observations of the movement of the magnetic poles over time. Additionally, observations of magnetic anomalies in the Earth's crust provide further evidence of changes in the magnetic field.
