scientists can use rocks to learn about magnetic field by using what you called a solor wind to find out about the magnetic field and how it works :)
(?So imma take a Guess ? if its wrong please correct it ?)
When molten materials hardens into rocks of the ocean floor , the direction of Earth's magnetic field at the time is permanently recorded .
answered by a 6 grader ?Please correct me if i'm wrong I know i am

∙ 14y agoSediments that form sedimentary rock are laid down horizontally, most often at the bottom of bodies of water. This means that the youngest deposits are closest to the surface and the oldest are at the bottom (with some geologic exceptions). The further from the surface the layer is, the further back in the area's geologic history it is.
Sedimentary rock is nature's archive for the storage of information of ancient plant and animal life, and the recording of environmental conditions.
Much of the history of Earth is recorded in sedimentary rock, from organisms that were covered in sediments which lithified into rock. Particles in sediments can also point to the origins of materials that were eroded, the locations of continents in the past, the dates of island formation, the age of mountains, the climate at the time the sediments were deposited, the animal and plant life at the time of deposition, the timing and direction of glacial ice flows, sea level changes, and the causes of extinction events such as asteroid impacts and volcanism.
Sedimentary rock is truly the history book of Earth. The composition of, and fossil records found in, sedimentary rock, are a window to the organisms, climate, catastrophes and geography of the planet Earth of the past, and is key to aiding our understanding of the present and future.

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
Which direction will a magnet point to and why?
A magnet always has two faces or 'poles'. One is called north, because it will be attracted to the north pole of the earth if allowed to freely rotate. The other is called south because it will be attracted to the south pole of the earth. The earth itself acts like a magnet. The north pole of the earth actually has a south magnetic polarity and therefore attracts the north pole of a magnet. A compass needle is a magnet in which the arrow that points north has a north magnetic polarity.
How can you show appreciation for the work of scientist in the field of electricity?
I can think of a number of ways in which it would be possible to show appreciation for the work of a scientist in the field of electricity. First, learn about the work so that you fully understand it. See if you can build on it or follow lines of research to new and fruitful conclusions. See if you can get the US Post Office to issue a commemorative stamp for this scientist. See if you can get your local school board to name a school after him or her. Print commemorative T shirts. Do a beautiful oil painting of that scientist, with a symbolic background showing relevant electrical phenomena. Create a life sized bronze statue of the scientist. Name your first born child after him or her.
How do you explain gravity to kids?
because the earth is round & we don't fall off, something is holding us upon this earth, that my-dear-children, is GRAVITY! hehe. you'll learn about it more when you're older tell em.
What did you learn about earth science?
Personally, I've learned quite a lot about earth science in my life. What have you learned about earth science? "Never carry rocks away from the truck". The type of rock or truck is not important; in fact this rule applies in many situations not involving either rocks or trucks. It saves a lot of inconvenience and needless effort.
What did scientist learn about earth's beginning in the 1800?
about the spinning of the earth
Scientist learn about the earth's interior by studying what?
geology
What can we learn from studying a planet's magnetic field?
The size and fluidity of the core of the planet.

What natural accurence help scientist learn about the layers of earth?
hi
Earth scientist strive to help people learn to do what?
invest their money
What have scientists observed in order to learn about earth's interior?
The Earth's size and overall density The Earths Geological features The Earths magnetic field The variations in observed gravity and magnetic fields as compared to the a theoretical model of what these should be. The variations in speed of and type of seismic waves as they propagate through the earth after a man made explosion or earthquake. Meteoric material that has fallen to earth.
Scientist learn about the earth's interior by studying?
Scientist learn about the earth's interior by studying seismic waves. 'P' waves travel all the way through Earth's crust, mantle, outer and inner core and give scientists a glimpse of the interior.
Where do geologists get indirect evidence to learn about earth's interior?
From gravity and magnetic surveys and from seismic information.
Can astronomers learn the magnetic field of a star?
Light that comes from the sun is polarized by these magnetic fields. A meter can determine the different directions of the light and detect interference. This interference is known as a magnetic field.

The other is called south because it will be attracted to the south pole of the earth. The earth itself acts like a magnet.

What is the magnetic field of Mars like?
Mars no longer has a magnetic field. Look at earth for a moment. The earth's magnetic field is generally thought to be the product of dynamo action associated with motion (currents) in the molten fluid core of the earth. Other planets that have magnetic fields are, in general, thought to have this same or a similar source for their fields. Mars no longer has a molten core. Our studies have revealed that there are parts of the crust of Mars that have been magnetized. We see that these areas have a residual magnetic field that has been left as an "impression" of the original magnetic field of the red planet. And that field has changed polarity at different times over the period when Mars still actually had a natural magnetic field and it magnetized portions of the crust. A link to the Wikipedia article on Mars is provided.
