How did the study of paleomagnetism help prove wegener's hypothesis?

∙ 15y ago
Before discovering that rocks are imprinted with the direction of magnetic orientation that exists at the time of their creation, no proof existed to confirm Wegener's hypothesis. When rocks were examined from both sides of the Mid-Ocean Ridge, the magnetic orientations were found to be mirror images of each other, indicating that the seafloor was spreading outward, and therefore pushing the continents apart.

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 techique is used to study ancient magnetic fields?
Paleomagnetism refers to the study of the record of the Earth's magnetic field preserved in various rocks and minerals through time.The study of paleomagnetism is possible because iron-bearing minerals such as magnetite may record past directions of the Earth's magnetic field when the rocks containing them were formed or last heated up.Paleomagnetic signatures in rocks can be recorded by three different mechanisms:-First, iron-titanium oxide minerals in basalt and other igneous rocks may preserve the direction of the Earth's magnetic field when the rocks cool through the "Curie temperature" for those minerals. (The Curie temperature of magnetite, is about 580°C).In a completely different process, magnetic grains in sediments may align with the magnetic field during or soon after deposition.In a third process, magnetic grains may be deposited from a circulating solution, or be formed during chemical reactions, and may record the direction of the magnetic field at the time of the mineral's formation.
What do ictheologists study?
what is about Ictheologists study
What is the study of rocks and minerals?
The study of minerals is called mineralogy. The study of rocks is called petrology.
The study of rocks?
The study of rocks is is called geology but a person who study's them is called a petrologist
What is the study of the magnetic record preserved in Earth's rocks called?
paleomagnetism
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 do scientists study when they study paleomagnetism?
They study magnets and all that stuff
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 is the study of the past magnetism in rocks known as?
This is known as paleomagnetism.
What is the study of the Earth's magnetic field is known as?
it's paleomagnetism
What does asking questions help scientistt do?
Asking questions helps the scientis to study more in order to prove his hypothesis true
What is paleomagnitism?
Paleomagnetism is the study of rock magnetism in order to determine the intensity and direction of Earth's magnetic field in the past.
Advantage of hypothesis testing?
1) Determine the focus & direction for a research effort. 2) Development of a hypothesis forces the researcher to clearly state the purpose of the research activity. 3) Determine what variables will not be considered in a study, as well as those that will be considered.
Can research be undertaken without developing a hypothesis?
Yes, Research can be undertaken without framing a hypothesis. The justification is in case of explanatory research, where the aim of your research is not to prove or disprove something, but to undertake an in depth study and go on exploring the investigation !!!!
Why is planning experiments important to study?
Only when experiments are planed, carried out and analyzed can we know if our hypothesis is true and our methods are reliable. Oncethis is achieved, repeating experiments prove validity.
