While studying the ocean floor, scientists found alternating bands of magnetism. Each band is magnetized with a polarity that is opposite the surrounding bands.

Studying the magnetic patterns of the rocks in the floor of the ocean helps scientists do what?
It helps them determine the frequency of shifts in the magnetic orientation of the Earth, and initially led to the confirmation of seafloor spreading at the mid-ocean ridges.
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 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 did scientist discovere when they analyzed the magnetic bands on the ocean floor?
Scientists found Alternating bands of magnetism.
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 is a sentence using the word fissure?
"In anatomy, a fissure is a deep groove in any of various parts of the body." "The scientists were studying a deep fissure in the ocean floor." "Steam was erupting from a new fissure in the area of the geysers."
Why do scientists look to the ocean floor to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.
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
What are the three technologies for studying the ocean floor?
Alvin, Sonar , and underwater vessels
How did scientists determine how the ocean floor is?
Radiometric Dating.. APEX!
