The patterns of iron particles found in sea floor rocks result from what?
The earths magnetic polarity at the time of rock formation.
What is the significance of the patterns of offsets along mid-ocean ridges?
the matching patterns on either side of the mid-ocean ridge could be explained by new ocean crust forming at the ridge and spreading away from it as ocean crust forms it obtains the polarity of the earth's magnetic field at that time over time the strength of the earths magnetic field changes when new ocean crust forms at the center of the spreading it obtains a new kind of magnetic polarity over time a series of magnetic ''stripes'' are formed
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 happens to metamorphic rock?
It is changes over time
How has the amount of earths radioactive isotopes changed over time and why has it changed?
They have been slowly declining over time because they decay, eventually becoming stable isotopes of other elements.
What happens when earths plate collide?
Over time, they form a mountain range

What happens to the air over the sea during night time?
hagu falls to earths surface and every one dies because of its smell. then the imam coms and eats it with ponir
Will the polarity of the earths magnetic field change in 2012?
There is no reason to believe that the Earth's magnetic field will change any time soon... or, for that matter, that anything extraordinary is going to happen in 2012.
How do foothills change over time?
When earths plates collide together
What is the significance of the patterns of offsets along mid-ocean ridges?
the matching patterns on either side of the mid-ocean ridge could be explained by new ocean crust forming at the ridge and spreading away from it as ocean crust forms it obtains the polarity of the earth's magnetic field at that time over time the strength of the earths magnetic field changes when new ocean crust forms at the center of the spreading it obtains a new kind of magnetic polarity over time a series of magnetic ''stripes'' are formed
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.
Explain how the reversal of earths magnetic poles can be produce a calendar for part of earths history?
In rock formed when the sea floor is being built, such as at the mid-Atlantic ridge, the minerals preserve the magnetic polarity. Since the flipping of the poles is fairly regular, the count of the bands can give a time.
What is the geomagnetic reversal time scale?
The geomagnetic reversal time scale has patterns of polarity. It is the pattern of alternating and reserved polarity in rocks.
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 is the process that causes the changes in the location of earths continent over time?
The process that causes changes of the Earth's continents over time is called "Plate Tectonics."
