How can scientist use rocks to learn about earth magnetic field?

Answer 1

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 .

Answer 2

Sediments 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.

Answer 3

Scientists can study the magnetic minerals in rocks to determine the direction and intensity of the Earth's magnetic field at the time the rocks formed. This information helps in understanding the geological history of the Earth's magnetic field and how it has evolved over time. By analyzing the magnetic properties of rocks, scientists can also track the movement of tectonic plates and study past changes in the Earth's magnetic field.

Answer 4

Beacuse of it's design

Answer 5

Some rocks can be magnetic because they have special minerals like nickel, steel, ect.
