The orientation of a rock’s magnetic field can tell you its?
The orientation of a rock's magnetic field can tell you the direction in which the rock was formed, as the magnetic minerals in the rock align themselves with the Earth's magnetic field at the time of formation. It can provide insights into the geological history of the rock, including its age and past movements.
How can you tell from the pictures where the magnetic fields are the strongest?
You can tell where the magnetic fields are strongest in a picture by looking for areas where the magnetic field lines are closest together, indicating a higher field strength. The density of the field lines represents the strength of the magnetic field.
How do magnetic stripes show the history of Earth's magnetic field?
as you move away from an ocean ridge the rocks get older
How can scientists tell when changes occur in earths magnetic field?
Scientists follow the magnetic field lines of the earth and measure them regularly. They will compare the earlier measurements and note the changes in position of the magnetic axis and decide if it is changing or not! Also if there are sudden changes observed in magnetic field lines bec of solar flares from sun. Magnetism is an interesting chapter! learn more by watching and subscribing to this space @PhysicsFusion-sm3tr Hope this helps
How can scientist tell that earth's magnetic field sometimes reverses direction?
You don't have to be a scientist to observe that fact. All you have to do is take any magnet and hang it up on a thread, so it's free to rotate and point wherever it wants to point. When you do that, you find that every magnet that's free to turn always turns to point at the same place ... a spot in far northern Canada. When you do this experiment with thousands of magnets in thousands of places all over the earth, and keep records of the direction that magnets point in various places, it all goes together to give a beautiful diagram of the earth's magnetic field. People who do a lot of traveling over long distances have used this fact for thousands of years to build a device that helps them find their way around the surface of the earth. The device is called the 'magnetic compass'.

How can the magnetic orientation of rocks be used to trace a continent that has drifted?
When rocks are formed, usually from lava flows, the magnetic orientation of them is set as they solidify. As these rocks are affected by continental drift and other factors such as earthquakes, the original magnetic orientation remains. Using the known strengths of the earth's magnetic field over time, it is possible to then tell where these rocks originally emerged.
What do lava samples tell scientists about what has happened to the earth magnetic field over geologic time?
The magnetic field periodically changes its orientation.
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.
Why do magnetic strips appear on seafloor?
Magnetic strips appear on the seafloor because it spreads apart, forming new rocks that have a magnetic properties.

How can scientists tell if the earths magnetic field has changed?
Sediment cores taken from deep ocean floors tell scientists about magnetic polarity shifts which provides a direct link between magnetic field activity and the fossil record . The Earth's magnetic field determines the magnetization of lava as it is laid down on the ocean floor on either side of the Mid-Atlantic Rift where the North American and European continental plates are spreading apart . When the lava solidifies it then creates a record of the orientation of past magnetic fields much like a tape recorder records sound .

What does the relative density of lines of a magnetic field tell us about the strength of the field?
The relative density of lines in a magnetic field diagram indicates the strength of the magnetic field in that region. A higher density of lines represents a stronger magnetic field, while a lower density indicates a weaker field. The spacing between the lines also gives an idea of the field's intensity, with closer lines indicating stronger magnetic force.
How do magnetic stripes form on the ocean floor and how are they significant?
They form by the cooling of ferrous rock at the time it transitions from a molten state to a solid state. The ferrous particles are trapped in the orientation of the earths current magnetic field. The earths magnetic field alternates every certain number of years (a huge number like 500,000 years.) Since rock will cool at different times alternating layers of rock can have a completely opposite magnetic orientation. They are useful because you can tell the relative age of the different layers of rock based on this evidence. Hope this helps. Very brief and crude explanation.
