Magnetic particles suspended in liquid magma align themselves with the Earth's field, and when the magma solidifies they retain that alignment even after the direction of the Earth's field changes. So, for instance, as magma spreads outward from the Mid Atlantic ridge, you get a series of magnetic strips of varying alignment as you move outward, and the strips on the west side correspond with those on the east side.

What is the evidence of plate tectonics?
There are two main evidences of plate tectonics: Paleomagnetism- We find that ancient rocks have preserved the magnetism of Earth that was present at that time. Studying the paleomagnetism records, we have found out the polar wandering path, i.e. the path through which the poles moved on the surface of the Earth. The polar wandering path shows clearly that the continents were in a different position than they are now. Even Earth's field reversals are recorded in the rocks. Earthquake patterns- The earthquake patterns clearly mark the boundaries of the crustal plates which further boosts the credibility of the plate tectonics model.
What is a map hearing?
A "Mapp" hearing is a pre-trial hearing on whether or not to suppress a piece of evidence that is going to be introduced at trial. The evidence could be tangible evidence, such as an illegal substance, or intangible evidence, such as a confession.
If evidence has been moved prior to photography what should you do?
If any evidence was moved by the first responders prior to your arrival, photograph it's present location and condition. Never have the officer place the item of evidence back where it was originally located.

Is there any evidence of art for this hominid group?
Is there any evidence of art for thi hominid group?
Paleomagnetism is proven by evidence of changes in?
Evidence of paleomagnetism can be found in basalt that has cooled from lava. Other evidence is that any rock with magnetic minerals are presents, and sedimentary rocks where minerals form from ion bearing ground water.
What is the study of the magnetic record preserved in Earth's rocks called?
paleomagnetism
Who invented the paleomagnetism theory?
No one person invented or developed the theory of paleomagnetism. Several different scientists contributed to the development of the theory of paleomagnetism.
How does paleomagnetism affect humans?
Paleomagnetism refers to the magnetism found in rocks that was induced by the earth's magnetic field. A deeper understanding of the concepts behind paleomagnetism could positively impact the lives of humans.
Is paleomagnetism the study of ancient magnetism?
Paleomagnetism is the study of the magnetism of ancient rocks. In principle, it was the study of ancient magnetism
What are two pieces of evidence for continental drift?
1. Fossils that can be found in many continents and cannot be explained for their presence in the present day we live in. (Such as the glossepteris species.) 2. Paleomagnetism
What three pieces of evidence did Harry Hess gather to prove that seafloor spreading was taking place?
Three evidence that supports Harry Hess theory of Seafloor Spreading is; 1. Paleomagnetism. 2. Plate Tectonics. 3. Polar Wondering and Polar Reversal.
What did scientist Henry Hess invent?
Paleomagnetism
What has the author Allan Verne Cox written?
Allan Verne Cox has written: 'Review of paleomagnetism' -- subject(s): Magnetism, Terrestrial, Paleomagnetism, Terrestrial Magnetism
What is paleomagnetisim?
Paleomagnetism is the study of the record of the Earth's_magnetic_fieldpreserved in various MagneticMineralthrough time. The study of paleomagnetism has demonstrated that the Earth's Magnetic_fieldvaries substantially in both orientation and intensity through time.
What are three types of paleomagnetism?
dia, para, ferro magnetism
What is the study of the past magnetism in rocks known as?
This is known as paleomagnetism.
