Scientists found out about normal polarity and reverse polarity. Normal polarity is when the North Pole is south and the South Pole is north and reverse polarity is the opposite. The magnetic bands are different colors for normal and reverse polarity. This can cause sea-floor spreading.
What else can I help you with?
What kinds of magnetism did scientists finds while studying the ocean floor?
Scientists found evidence of magnetic stripes on the ocean floor, which indicated periodic reversals in Earth's magnetic field. This discovery helped support the theory of plate tectonics and seafloor spreading.
Why do scientists look to sedimentary rocks when studying the history of the Earth?
The vast majority of fossils are found in sedimentary rock.
What can scientists learn about from fossils found in sea floor sediment?
The climate at the time the fossile was preserved. :)
What evidence of sea floor spreading has come from?
Evidence of sea floor spreading has primarily come from the analysis of mid-ocean ridges, where new oceanic crust is formed by volcanic activity. Scientists have observed symmetrical patterns of magnetic striping on either side of these ridges, indicating that new rock is created and then moves outward as tectonic plates shift. Additionally, the age of ocean floor sediments increases with distance from the ridge, showing that the youngest material is found at the center of the ridge. These findings support the theory of plate tectonics and the dynamic nature of the Earth's surface.
How did scientists discover that rocks get older from the mid ocean ridge?
They discovered a pattern of reverse and normal polarity in the rock bodies of the ocean floor that indicated that oceanic crust was constantly being formed over time. Polarity shifts in the Earth had already been noted in continental crustal rock. With the advent of radiometric dating, core samples were taken and dated, confirming that the youngest rock is found at the ridge and rock age advances with distance from the ridge.

What did scientist discovere when they analyzed the magnetic bands on the ocean floor?
Scientists found Alternating bands of magnetism.
Are xenomorphs real?
Yes, military scientists have have found these creatures and been studying them for a while, as well a other aliens i.e. Greys and Martians.
What ended the monotony of the crew members who were studying the television screen?
Pictures, or scattered debris on the floor of the ocean appeared.
What on the ocean floor is evidence that earths magnetic field changes?
Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.
Was King Tutankhamuns tomb open when it was found?
no it wasnt ,but grave robbers stole from it opening it. scientists know this because they found gold braclets and a bag of gold items on the floor. d.b.d
What are the Three ideas scientist have found to support ocean floor spreading from the ridge?
The first one is the sonar used to map out sensed mountains,the second one is scientists found strange rocks shaped like pillows in the central valley of the mid-ocean ridge and the last one is scientists discovered that the rock that makes up the ocean floor lies in pattern of magnetizied "stripes"
What might historians and scientists learn by studying this burial site?
Historians and scientists may learn about the culture and practices of the people who were buried at the site, including their beliefs, social structure, and customs. By analyzing the remains, they can gather information about health, diet, and living conditions of the individuals. Studying the artifacts and grave goods found in the burials can provide insight into the material culture of the society.
What were found on the ocean floor?
blank are found on the ocean floor
What did scientists learn by studying the rocks astronauts brought back from the moon?
Scientists learned important information about the moon's formation, history, and composition by studying the rocks brought back by astronauts. They found that the moon is much older than previously thought, provided evidence of past volcanic activity, and discovered similarities between moon rocks and certain rocks on Earth.
