Studying the magnetic patterns of the rocks in the floor of the ocean helps scientists do what?
Studying the magnetic patterns of ocean floor rocks helps scientists understand the movement of Earth's tectonic plates and past changes in the Earth's magnetic field. This information is crucial for reconstructing the history of plate tectonics and understanding the processes that shape the Earth's surface.
What do strips of low intensity magnetism represent on the ocean floor?
it represents the fact that the magnetic poles of the Earth must "flip" from time to time - the iron in the magma that cools to become the ocean floor aligns with the poles so stripping would show that the poles have changed direction over time. Some scientists suggest the times when the poles "flip" match up with cataclysmic events in the Earths geologic history.
What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
Describe how magnetism is used to support the theory of seafloor spreading?
New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.

What did scientist discovere when they analyzed the magnetic bands on the ocean floor?
Scientists found Alternating bands of magnetism.
Why do Earth's magnetic pole reversals provide evidence for plate tectonics?
Earth's magnetic pole reversals are recorded in rocks as they cool and solidify. When rocks form, they preserve the orientation of Earth's magnetic field at that time. By studying the magnetic alignment of rocks on the ocean floor, scientists have discovered patterns that support the theory of plate tectonics, such as the symmetrical magnetic striping on either side of mid-ocean ridges.
Why didn't scientists know a lot about the ocean floor prior to the 1950s?
Scientists didn't know much about the ocean floor before the 1950s because technology at the time limited their ability to explore deep underwater. The development of sonar technology and submarines during the 1950s allowed scientists to collect more data and map the ocean floor more accurately. Additionally, prior to this time, most research efforts were focused on studying the land, so the ocean floor remained largely unexplored.
Why is the cat sleeping on the floor?
The cat is sleeping on the floor because it finds it comfortable and relaxing.

Which method of studying the ocean floor allows oceanographers to be closest to the ocean floor?
minisubmarines
What pattern can be seen when the studying the magnetism of the ocean floor?
The appended article goes into some detail on this topic. Basically there are lines of strong and weak magnetic forces running north and south parallelling the mid ocean rift in the Atlantic. These are mirrored on each side of the rift.
What are challenges in studying the ocean floor?
the darkness and the weather condition
How do scientists make maps of the ocean floor?
Sonar

Is it true that the magnetism of the rocks along the ocean floor is consistent in that there is no reversal of polarity?
The rocks of the ocean floor are not consistent and do show past reversal of polarity. The statement in the question is false.
What are the scientist who work on the ocean floor called?
Scientists who work on the ocean floor are called marine biologist
