What are magnetic anomalies?
Magnetic anomalies occur where vast deposits of iron ore have caused a local deviation in the Earth's magnetic field.Any place where the Earth's magnetic field is not smooth and uniform.Some are so minor that they can't be detected without a million dollars worth of fancy equipment, some you can detect with a pocket compass.
What do bands of rock on the seafloor showing alternating magnetic orientation indicate about the earths magnetic field?
They indicate that the Earth's magnetic field has undergone shifting of the positions of it's poles several times in the past.
First related the symmetrical magnetic patterns in seafloor basalts to seafloor spreading at a mid-ocean ridge?
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.
Why does the earth have its own magnetic field?
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
Where is magnetic variation greatest on Earth?
The magnetic variation is greatest on earth at greggs in pakistan.... no need to thank me for the answer
Why is the North Pole on the earth not the North Pole?
Because of magnetic anomalies in the earth's plates, the magnetic north pole moves slightly to different places.
Regions of the sea floor with negative magnetic anomalies were formed during times when Earth's magnetic field was or had?
reverse polierty

A device that uses the Earth's magnetic field to indicate which way North is?
That is called a magnetic compass.
Does planet Venus has marine magnetic anomalies?
yes
What do magnetic anomalies provide evidence of?
seafloor spreading
What do bands of rock on the seafloor showing alternating magnetic orientation indicate about the earths magnetic field?
They indicate that the Earth's magnetic field has undergone shifting of the positions of it's poles several times in the past.
Who found the evidence of the earth's magnetic field reversal?
The US Navy while performing a careful survey of magnetic compass anomalies in the early 1950s to improve navigation. The data and the survey was originally classified.
Bands of rock the seafloor showing alternating magnetic orientation indicate earth's magnetic field has?
reversed itself in the past. hth :)
What has the author Dwight Edward Eggers written?
Dwight Edward Eggers has written: 'Downward continuation and transformation of potential fields with application to marine magnetic anomalies' -- subject(s): Magnetic anomalies
What does the presence of a magnetic field on Earth compared with other terrestrial plants indicate?
Plants don't have a significant magnetic field. Perhaps you mean "planets"?
